Security for business financing - mortgage, registered pledge, assignment, promissory note, guarantee and Article 777

A company may receive two financing offers with a similar amount and cost but very different consequences. One may be secured by a mortgage over property. The other may require an assignment of contract receivables, a registered pledge over machinery, a shareholder's guarantee, a promissory note or a declaration made in a notarial deed.

These solutions are not interchangeable names for the same document. They relate to different assets, people and rights. They also affect the company's operations, its ability to sell assets, arrangements with customers and the way a claim may be enforced if the financing is not repaid.

There is no single form of security that is best for every company. The structure should match the amount, purpose, term, repayment source and assets available in the particular transaction. Before signing an agreement, a business should therefore understand not only the name of the security, but also its scope, establishment costs, activation conditions and release procedure after repayment.

Important: this material is educational and does not constitute financial or legal advice. It describes general rules and examples of security used in business financing. The scope of liability, documents, costs and obligations depends on the agreement, parties to the transaction, type of claim, subject of the security and current Polish law. Before signing, the documents should be reviewed with the financing provider and a qualified legal adviser.

Short answer: how do the main forms of security for business financing differ?

A mortgage links security to real estate, while a registered pledge most often relates to movable property or a transferable property right. An assignment transfers a particular receivable or the associated rights to the financing provider. Suretyship introduces an additional person responsible for performing the obligation. A promissory note creates a formal obligation governed by Polish promissory note law. A declaration under Article 777 of the Polish Code of Civil Procedure may shorten the route to enforcement if the conditions stated in the notarial deed are met.

One financing agreement may use several forms at the same time. This does not mean that more security is always better. Each element should serve a defined purpose and remain proportionate to the amount, term and risk of the transaction.

Form of security	What is it linked to?	What is required?	Main function	What should the company check carefully?
Mortgage	Real estate or certain rights connected with real estate	Relevant documents and an entry in the land and mortgage register	Allows the creditor to seek satisfaction from the encumbered right under the applicable statutory rules	Ownership, Section IV of the register, priority, mortgage amount and release conditions
Registered pledge	Movable property or a transferable property right	A written pledge agreement and an entry in the Register of Pledges	Links the claim to a defined asset that may remain in use by the business	Ownership, identification, value, existing encumbrances and rules for using the asset
Assignment of receivables	The right to receive payment from a customer	An assignment agreement and a review of the underlying agreement and any assignment restrictions	Transfers a defined receivable to the financing provider	Whether the receivable exists, is undisputed, transferable and properly documented
Promissory note	The promissory note obligation of the issuer and any other person signing the note	A document meeting the requirements of Polish promissory note law and, for a blank note, an agreement governing completion	Creates a separate formal payment obligation	Completion rules, maximum amount, due date, notice and return after repayment
Suretyship or guarantee	The liability of an additional person or entity	A written declaration by the surety and a precise definition of the secured obligation	Allows the creditor to seek performance from the surety as well	Scope, amount, duration, joint and several liability and the impact on the surety's assets
Article 777	A declaration of voluntary submission to enforcement	A notarial deed containing the required elements	May make it possible to obtain an enforceable title without a standard action for payment	Amount, triggering event, deadline for applying for an enforcement clause and scope of the declaration

Security is not a source of repayment

Valuable property, machinery or a signed promissory note may reduce part of the financing provider's risk, but they do not automatically generate the cash required to pay instalments. The primary repayment source should be operating cash flow, payment from a contract, sale of the financed inventory, rental income or another clearly identified inflow.

Security answers a different question: what protects the creditor if the repayment plan is not carried out? An assessment therefore usually covers two levels:

whether the business is expected to generate enough cash to repay the financing on time
what position the financing provider will have if that scenario fails

This distinction also matters to the business. If repayment depends entirely on selling the property or machinery offered as security, the company should carefully consider whether the financing is supporting growth or merely postponing an underlying problem.

Before applying, the company may use our business loan readiness checklist. It helps separate the value of the security from the ability to service the obligation.

How should a company compare security before signing an agreement?

The comparison should begin with five questions.

1. What will repay the financing?

If repayment is expected from a specific invoice or contract payment, an assignment may be directly linked to that inflow. If the financing supports a larger investment and will be repaid over several years from the business as a whole, longer-term security over real estate or another asset may be more relevant.

2. Which assets or rights can the company legally use as security?

Using machinery, property or a vehicle is not the same as owning it. The company must confirm ownership, third-party rights, existing encumbrances and whether another security interest can be established. With an assignment, it must also verify that the receivable exists and that the underlying contract does not restrict its transfer.

3. How will the security affect daily operations?

The company should know whether it may continue using the asset, sell it, replace it, move it to another location or establish another right over it. With an assignment, customer communication and payment instructions matter. With suretyship, the consequences also extend to a third party.

4. How much time and documentation will establishment require?

An entry in the land and mortgage register, an entry in the Register of Pledges, a notarial deed and confirmation of an assignment are separate procedures. The company should establish which steps are conditions of the decision, agreement and payout, and which may be completed later.

5. How will the security be released after repayment?

The agreement should state who will issue the documents required to remove a mortgage or pledge, return the promissory note, end the assignment or release the surety, and by what deadline. Repayment does not always remove an entry from a register automatically.

Mortgage - security linked to real estate

A mortgage may secure a defined claim over real estate or certain rights listed in Polish law. Under Article 65 of the Polish Act on Land and Mortgage Registers and Mortgages, the creditor may seek satisfaction from the encumbered property regardless of who becomes its owner, with priority determined under the applicable rules. A mortgage is created when it is entered in the land and mortgage register.

This form of security may fit a larger amount and a longer financing term, especially when the company or a third party owns property with a verifiable legal status and value. It does not mean that an asking price is equal to the available financing amount. The type and location of the property, existing encumbrances, marketability, valuation and expected LTV all matter.

Before establishing a mortgage, the company should review:

who owns the property and who may establish the security
what is disclosed in Sections III and IV of the land and mortgage register
the mortgage amount to be entered
which claims the security covers
whether the property is already encumbered and how priority will work
who pays valuation, notarial, court registration and insurance costs
when the creditor will issue consent to remove the mortgage after repayment

The mechanism, use cases and limitations are explained in Secured loan against real estate for businesses - when does it make sense and how does it work?. When estimating the possible amount, see our guide to LTV in a business loan. The document checklist is available in Which documents should you prepare for a property-secured business loan?.

Registered pledge - security over machinery, vehicles or rights

A registered pledge may cover movable property and transferable property rights. In practice, it may be considered for machinery, equipment, vehicles, production lines, specified collections of assets or other property that can be properly identified and valued.

Under Articles 2 and 3 of the Polish Act on Registered Pledges and the Register of Pledges, establishing the security requires a written pledge agreement and an entry in the Register of Pledges. The asset may remain in the company's possession and continue to be used in the business unless the agreement provides otherwise.

The key issues are:

evidence of ownership
an unambiguous description of the asset
technical condition and insurability
market value and an actual secondary market
earlier pledges, leasing arrangements, title transfers or third-party rights
rules concerning inspection, servicing, relocation, sale and replacement
documents required to remove the pledge after repayment

The original purchase price of a machine does not determine the quality of the security. The amount that could realistically be recovered through a sale, the time needed to find a buyer and the costs of dismantling, transporting and preparing the asset also matter.

The full process is explained in Registered pledge in business financing - how does security over machinery and equipment work?.

Assignment of receivables - security linked to a customer's payment

An assignment of receivables transfers the right to receive payment to another party. Article 509 of the Polish Civil Code provides that, as a rule, a creditor may transfer a receivable without the debtor's consent unless this is prohibited by law, a contractual restriction or the nature of the obligation. Rights associated with the receivable are transferred with it.

In business financing, the assignment may cover one invoice, a group of receivables or amounts arising under a contract. Its advantage is the direct connection between the security and the planned cash inflow. Its limitations may include an assignment ban, a dispute about performance, set-off rights, payment dependent on acceptance or insufficient documentation.

Before signing, the company should check:

the agreement from which the receivable arises
whether it already exists or is future or conditional
whether the agreement contains an assignment ban or restriction
whether customer consent, confirmation or notification is required
whether the customer may raise set-offs, complaints or other defences
the account to which payment must be made
what happens to the assignment after the financing is fully settled

The communication process is described in How to get your customer's consent for the assignment of receivables. If the need arises from a specific project, it is also useful to compare contract, invoice and purchase order financing.

Promissory note - a formal obligation that must be read together with the completion agreement

Business financing in Poland may involve a promissory note, including a document that is incomplete when issued, commonly called a blank promissory note or weksel in blanco. Polish Promissory Note Law sets out the required elements of a promissory note. Article 10 deals with a note that was incomplete when issued and was later completed contrary to the agreement between the parties.

A blank promissory note is usually accompanied by a declaration or completion agreement. This document should explain when and how the financing provider may complete the note. Signing a blank document without understanding the completion rules creates a risk that should not be treated as a routine administrative formality.

Before issuing the note, the company should check:

which obligation it secures
the maximum amount for which it may be completed
which claims may be included in the promissory note amount
which event allows the holder to complete it
whether and how the issuer will be notified in advance
the due date and place of payment that may be entered
who else signs the document and in what capacity
when the note will be returned or destroyed after repayment

A promissory note is not the same as civil-law suretyship or voluntary submission to enforcement under Article 777. It should not be treated as automatic enforcement without any court involvement. Its effects depend on the wording, the completion process, the parties and the applicable procedural rules.

Suretyship - liability of an additional person or entity

Under a suretyship agreement, the surety undertakes towards the creditor to perform the obligation if the debtor fails to do so. Article 876 of the Polish Civil Code requires the surety's declaration to be made in writing to be valid. Unless the parties agree otherwise, Article 881 provides that the surety is liable in the same way as a jointly and severally liable co-debtor.

The surety may be a shareholder, a group company or another person or entity accepted in the particular transaction. For the financing provider, this creates an additional party from which performance may be sought. For the surety, it is a real financial exposure, not merely a recommendation or confirmation of confidence in the project.

Before giving the guarantee, the surety should establish:

which obligation is covered and the maximum amount of liability
whether the guarantee covers interest, fees, costs and future amendments
how long it remains in force
when the creditor may demand payment from the surety
whether liability is joint and several
how the guarantee affects the surety's assets and existing obligations
when and how the guarantee expires

A shareholder's or director's guarantee for a company does not automatically turn every company debt into that person's private debt in every respect. The signed document and applicable law determine the extent of liability. The scope should therefore be clear, and the person signing should receive the complete documentation relating to the secured obligation.

Article 777 - an enforcement mechanism rather than an asset

Article 777 is often described as security, but its function differs from a mortgage, pledge or assignment. It concerns a declaration made in a notarial deed under which the debtor voluntarily submits to enforcement within a defined scope.

Article 777 of the Polish Code of Civil Procedure lists certain notarial deeds that meet the statutory requirements as enforcement titles. Before enforcement can begin, the creditor must still obtain an enforcement clause. A properly drafted deed may, however, make it unnecessary to bring a standard action for payment concerning the obligation covered by the declaration.

The document should be reviewed for:

the obligation covered by the submission to enforcement
the amount or method used to determine its maximum level
the event on which performance becomes due
the deadline by which the creditor may apply for an enforcement clause
the people or entities making the declaration
the relationship between the notarial deed and the financing agreement

Article 777 does not establish a mortgage, pledge or additional pool of assets from which the creditor will necessarily recover the claim. Its main function is to facilitate the transition to enforcement once the stated conditions have been met. The complete process and a checklist for the notary appointment are available in Article 777 KPC - what does voluntary submission to enforcement mean?.

Which form of security fits a particular business situation?

The table below shows the direction of the assessment, not a ready-made financing decision. The final structure depends on the documents, transaction value, financing provider's policy and arrangements between the parties.

Business situation	What may be considered?	Why?	What may limit the solution?
A larger investment, longer term and available property	A mortgage, sometimes combined with Article 777	The security can be linked to a durable asset with a documented legal status	Low value, existing encumbrances, lack of owner consent or limited marketability
The company owns valuable machinery or a fleet but does not have suitable property	A registered pledge	The asset may secure the claim and continue working in the business	Leasing, lack of ownership, a weak secondary market, difficult identification or other encumbrances
Repayment is expected from a specific invoice or contract	An assignment of receivables	The security is directly linked to the expected inflow	An assignment ban, conditional acceptance, dispute, set-off or poor documentation
The financing provider requires an additional formal payment obligation	A promissory note, often a blank note with a completion agreement	It creates a formal promissory note obligation under agreed rules	Unclear completion rules, excessive scope or no return procedure
A shareholder or another entity is also expected to be responsible for repayment	Suretyship or a guarantee	The creditor gains an additional party responsible for performing the obligation	The surety's insufficient financial position, unclear scope or lack of informed consent
The parties want to define the route to enforcement precisely	A declaration under Article 777	The notarial deed may shorten the route to an enforceable title	Defective wording, unmet conditions, expiry of the deadline or a lack of assets against which enforcement can be effective

Can one agreement use several forms of security?

Yes. A financing provider may combine several forms when each addresses a different element of risk. An assignment directs an expected contract payment, a pledge links the claim to machinery, suretyship adds another liable party and Article 777 defines a route to enforcement.

For example, a company is delivering a contract worth PLN 1,200,000 and needs PLN 600,000 for materials, payroll and subcontractors. Repayment is expected from the customer's payment following acceptance. The structure being assessed may include:

assignment of the contract receivable to link the financing to the expected payment
a registered pledge over equipment owned by the business as additional asset-based security
a declaration under Article 777 defining the scope of voluntary submission to enforcement

This is not a universal package and does not mean that three forms are always required. If the receivable is strong, the contract is properly documented and the amount and risk are lower, the structure may be different. A more complex transaction may require additional conditions.

The company should assess the complete package. An assignment, promissory note and guarantee that each look reasonable on their own may together create a much broader scope of liability than a superficial reading of each document suggests.

The secured amount does not have to equal the amount paid to the company

The mortgage amount, maximum secured amount under a pledge, amount that may be entered on a promissory note or limit stated in a notarial deed may exceed the principal advanced to the company. The security may also cover interest, fees, enforcement costs and other claims defined in the documents.

This does not mean that the company owes the full maximum amount from the date of signing. The maximum secured amount and current outstanding balance are different figures. Before signing, the business should understand:

which claims fit within the limit
how the current balance is calculated
whether the security covers one agreement or also other current or future obligations
when the limit may be used
how the company will receive a final settlement after repayment

This is particularly important when several forms of security cover the same claim. Their maximum amounts should not simply be added together and treated as the current debt, but the company must understand which rights the financing provider may exercise and in what order.

Which documents should the company prepare?

The required documents depend on the form of security. Some relate to the company and repayment source, while others are needed to assess a specific property, machine, receivable or surety.

Form of security	Initial documents	What should they confirm?
Mortgage	Land and mortgage register number, acquisition document, valuation report or valuation data, information on existing debt	Ownership, legal status, value, encumbrances and priority
Registered pledge	Purchase invoice or agreement, fixed asset register, serial numbers, technical documents and valuation	Ownership, identification, condition, value and the ability to establish the pledge effectively
Assignment	Contract, purchase order, invoice, acceptance report, correspondence and payment history	Existence, amount, due date, transferability and undisputed nature of the receivable
Promissory note	Draft note, completion agreement, main financing agreement and representation documents	Who signs, what the note secures and the rules under which it may be completed
Suretyship	Draft guarantee, surety's details, representation documents and information required to assess the surety's position	Identity, authority, scope of liability and the actual value of the guarantee
Article 777	Draft notarial deed, financing agreement, repayment schedule and documents describing the conditions for the claim becoming due	The obligation, maximum amount, triggering event, deadline and parties covered by the declaration

Documents should be organised before the final structure is agreed, not only immediately before signing. This makes it possible to identify a lack of ownership, an assignment ban, an existing entry, an outdated valuation or a representation issue earlier. We explain the broader assessment in How does business financing work step by step?.

Ten points to check in security documents

1. The secured claim

The document should make it possible to identify the agreement and claims it covers. The company should check whether the security applies only to one financing arrangement or also to other current or future obligations towards the same provider.

2. Maximum scope of liability

Review the mortgage amount, maximum amount secured by a pledge, maximum guarantee, rules for completing the promissory note and the limit stated in the notarial deed.

3. Events activating the creditor's rights

Failure to pay an instalment may not be the only triggering event. The agreement may also refer to a breach of information duties, deterioration of the security, lack of insurance, sale of an asset without consent or other events.

4. Obligations during the agreement

The security may require the company to maintain insurance, service equipment, provide documents, report disputes with a customer or obtain consent before taking specified actions.

5. Establishment and maintenance costs

Financing costs may be accompanied by notarial and court fees, valuation, insurance, registration and later removal costs. The company should determine who pays them and when.

6. Ability to sell or replace the asset

With a mortgage or pledge, the company should know whether the asset may be sold, replaced, relocated or exchanged for different security. With an assignment, a similar question concerns amendments to the contract and payment instructions.

7. Priority and existing encumbrances

The same asset may already be encumbered. A register entry does not always show the current outstanding debt, so an additional creditor statement may be required.

8. Valuation and reassessment rules

The company should establish whether the financing provider may require a new valuation, who pays for it and what happens if the value of the security falls materially.

9. Release conditions after repayment

The documents should define the deadline for issuing consent to remove a mortgage or pledge, returning the promissory note, ending the assignment and releasing the surety.

10. Combined effect of the complete package

Every security document should be read together with the main financing agreement and the remaining documents. Only then can the company see the full scope of liability, costs, ongoing duties and possible consequences of a breach.

When should the company pause and request clarification?

Further clarification is particularly important when:

the document does not clearly identify the obligation being secured
the maximum amount or method used to calculate it is unclear
a blank promissory note is to be signed without completion rules
the surety has not received the agreement they are expected to guarantee
the company does not know when an assignment will end
the pledged asset is not described unambiguously
the mortgage amount is confused with the current outstanding balance
the triggering conditions under Article 777 are inconsistent with the financing agreement
the security covers future obligations without clearly defined limits
there is no procedure for releasing the security after full repayment

Requesting clarification does not automatically mean that the document is defective. It allows both parties to confirm that they understand the mechanism and scope of liability in the same way. For a larger transaction, the cost of legal review may be small compared with the risk created by unclear security.

Summary

A mortgage, registered pledge, assignment, promissory note, suretyship and Article 777 serve different functions. The first two link the claim to a specific asset or right. An assignment directs a receivable from a customer to the financing provider. Suretyship extends liability to an additional person. A promissory note creates a formal obligation governed by promissory note law. A notarial deed under Article 777 may facilitate the transition to enforcement.

A sound security structure begins with the repayment source and the actual risk of the transaction. It should clearly define the subject, maximum scope, obligations during the agreement, costs and release process after repayment. Only this complete comparison shows whether the security fits the company's situation rather than merely matching the name of a financing product.

FAQ - security for business financing

What are the most common forms of security for business financing?

Business financing may involve a mortgage, registered pledge, assignment of receivables, promissory note, suretyship or a declaration of voluntary submission to enforcement under Article 777 of the Polish Code of Civil Procedure. One transaction may use several forms, depending on the amount, risk, repayment source and available assets.

Does providing security guarantee that financing will be granted?

No. Security is one part of the assessment. The financing provider usually also reviews the purpose, amount, company's position, documents, existing obligations and realistic repayment source. Valuable property or machinery does not replace the ability to service the financing.

Can one business loan have several forms of security?

Yes. For example, an assignment may be combined with a registered pledge, suretyship or Article 777 declaration. Each form should serve a defined function, and the complete package should be assessed for scope, cost and proportionality.

What is the difference between a mortgage and a registered pledge?

A mortgage concerns real estate or certain rights and is created by an entry in the land and mortgage register. A registered pledge may cover movable property and transferable property rights. Establishing it requires a written pledge agreement and an entry in the Register of Pledges.

Does an assignment of receivables require the customer's consent?

As a rule, a receivable may be transferred without the debtor's consent unless this is prohibited by law, a contractual restriction or the nature of the obligation. The company must therefore review the contract, any assignment ban and the requirements for consent, confirmation or customer notification.

Can a blank promissory note be signed without a completion declaration?

Polish law recognises a document that is incomplete when issued, but in practice it should not be signed without written completion rules. A declaration or agreement should define the secured obligation, triggering event, amount and notification procedure. A lack of clear rules materially increases the issuer's risk.

Is the surety liable in the same way as the company?

The scope depends on the document and applicable law. Unless the parties agree otherwise, the Polish Civil Code provides that the surety is liable in the same way as a jointly and severally liable co-debtor. The maximum amount, duration, covered claims and expiry conditions should be checked before signing.

Does Article 777 allow enforcement to begin immediately?

No, not automatically. A properly drafted notarial deed may be an enforcement title, but the creditor must obtain an enforcement clause and demonstrate that the conditions stated in the document have been met before the matter can proceed to enforcement.

Is the mortgage amount or Article 777 limit equal to the current debt?

Not necessarily. The document may state a maximum amount covering principal and other claims defined in the agreement. The current balance depends on the amount advanced, repayments, interest, fees and other settlements. The company should request a clear explanation of both figures.

What happens to the security after the financing is repaid?

Once the financing has been fully settled, the actions required by the agreement and applicable law should be completed. These may include issuing consent to remove a mortgage or pledge, returning the promissory note, ending the assignment or releasing the surety. The documents, deadlines and costs should be agreed in advance.
