Acknowledgement of debt: what and when?

What is an acknowledgement of debt?

An acknowledgement of debt (gældsanerkendelse) is a legal document in which a person or company, the debtor, confirms in writing that they owe another party (the creditor) a specific amount. The document works as a formal acknowledgement of an already existing debt and is primarily a piece of evidence rather than an agreement.

Unlike a debt instrument (gældsbrev), an acknowledgement of debt is typically drawn up after the debt has arisen, not as part of setting up a new loan. It is a document that establishes a factual situation rather than creating new rights and obligations.

Typical situations where an acknowledgement of debt is relevant:

• You have lent money to a friend or family member without a formal agreement and now want written documentation
• A business partner owes you money for goods or services supplied, and you want a formal basis
• There is disagreement about who owes what, and a signed declaration can clarify the matter
• You want to interrupt a limitation period and keep the right to demand payment of the debt

Acknowledgement of debt vs. debt instrument: the key differences

Many confuse the two types of document. Here is an overview of the central differences:

	Acknowledgement of debt	Debt instrument
When	After the debt has arisen	On setting up a new loan
Purpose	Confirms an existing debt	Documents a new loan relationship
Content	Acknowledgement of the amount and who owes whom	Loan terms, interest, repayment plan
Level of detail	Simple and brief	Detailed and exhaustive

A debt instrument is therefore more detailed and is a central part of the loan construction itself. An acknowledgement of debt is shorter and more direct and simply states that the debt exists and who owes whom.

What should an acknowledgement of debt contain?

For the document to be legally usable, it should as a minimum contain:

1. The parties' details

Full names and addresses of the debtor and creditor. If one of the parties is a company, state the CVR number and company form.

2. Acknowledgement of the debt

A clear and unambiguous statement that the debtor acknowledges owing the creditor a specific amount. The amount is stated precisely in kroner, as ambiguity harms the document's evidential value.

3. The origin of the debt

A short description of where the debt comes from, for example "loan provided on [date]", "unpaid invoice no. [X] for [service]" or "outlay in connection with [description]". This matters so that the debt can be identified precisely.

4. Interest

Does the debt bear interest? If so, state the interest rate and the basis of calculation. If nothing is stated, the debt is typically regarded as interest-free.

5. Repayment terms (optional)

An acknowledgement of debt can include information about when and how the debt is paid. This is not a requirement. If you want a detailed repayment plan, a debt instrument is more suitable.

6. Signatures and dating

Both parties should sign the document, stating the date. Witnesses are not required by law but can strengthen the document's credibility in a dispute.

Is an acknowledgement of debt legally binding?

Yes. A correctly drawn-up and signed acknowledgement of debt is a legally binding document that can be used as evidence in a civil case. The debtor's signature is a formal acknowledgement that can afterwards be difficult to get out of.

There are, however, important reservations to be aware of:

Limitation: debt in Denmark as a rule becomes time-barred after 3 years (section 3 of the Limitation Act). The period runs from the earliest time the creditor could demand payment. When the debtor acknowledges the debt, for example by signing an acknowledgement of debt, the limitation is interrupted, and a new period begins to run. This is one of the most practical reasons to draw up the document.

Invalid declarations: an acknowledgement of debt can be set aside if the debtor can prove that it came about through duress, deceit or exploitation. The invalidity rules of the Contracts Act cover, among other things, duress (sections 28 and 29), deceit (section 30) and exploitation of a person's difficult situation or dependence (section 31), and an unreasonable agreement can also be set aside under the general clause in section 36.

Use in business

In business, acknowledgements of debt are frequently used to document and establish outstanding payments:

• Supplier relationships: a supplier wants written confirmation that an invoice is acknowledged, even though payment has not yet been made
• Internal balances in groups: internal loans or outlays are formally documented before the year-end
• Restructuring and creditor matters: in the case of payment difficulties, debt to creditors is documented as part of a process
• Due diligence: on the sale of a business, outstanding debt can be required to be acknowledged in writing as part of the terms of the deal

An acknowledgement of debt in business is not a payment agreement in itself, but it is an important basis for a subsequent negotiation on repayment terms.

Practical advice

Document from the start. Many debts arise informally, for example a loan to a friend or an outlay on a colleague's behalf. The sooner you document the agreement in writing, the easier it is to remember the details and prove the debt if a dispute arises months or years later.

Use precise language. Avoid vague wording. "I owe you something" is not legally usable. The amount, origin and parties must appear precisely.

Keep a signed copy. Both parties should have a signed copy. Digital signatures are legally valid in Denmark, and it is an advantage to use a platform that provides a receipt for the signature.

Check the limitation period. If you have an old informal debt, you should draw up an acknowledgement of debt before the period expires. If the debt is already time-barred, you cannot force the debtor to sign.

Separate the acknowledgement from the payment agreement. Document the debt in the acknowledgement, and if necessary draw up a separate agreement on the repayment terms. That keeps the two questions apart and gives both parties clarity.

How to make a good acknowledgement of debt

A legally usable acknowledgement of debt does not require a lawyer, but it must contain all the relevant elements: the parties' details, a clear acknowledgement of the amount, the origin of the debt and both parties' dated signature. The document can be signed digitally by both parties and is ready for use as soon as the signatures have been obtained.
