Debt Acknowledgment Between Individuals: Guide, Template & Legal Rules
Everything you need to know to formalize a private money loan: mandatory clauses, legal validity, common mistakes, and tracking repayments.
What is an IOU / debt acknowledgment?
A debt acknowledgment (reconnaissance de dette) is a written agreement by which a person (the borrower) recognizes owing a sum of money to another (the lender) and undertakes to repay it under agreed terms.
Private agreement
Drafted directly between private parties without requiring a notary, it has full evidentiary weight when respecting legal requirements.
Interest-free loan
Between loved ones, loans are almost always agreed interest-free (0% APR). Formalizing protects the capital without altering generous intent.
Undeniable proof of debt
During tax audits or disputes, a dated and signed written agreement prevents reclassification as a taxable gift and proves the loan.
6 mandatory clauses for a valid debt agreement
Under Article 1376 of the French Civil Code, a solid debt acknowledgment must include:
1. Full identity of both parties
Full names, birth dates and places, and full postal addresses of both lender and borrower.
2. Amount in figures AND in full words
Crucial rule: the amount must appear in numbers and letters. In case of discrepancy, the written words prevail.
3. Creation date and repayment due date
Clear agreement date and deadline (or agreed installment payment schedule).
4. Initial disbursement method
Details on how money was delivered (bank wire is strongly recommended for bank audit trail).
5. Signatures of the parties
Signatures from borrower and lender, ideally backed by signatures from trusted witnesses.
6. Explicit 0% interest mention
Clear statement that the loan is interest-free to avoid any future ambiguity.
The Word template trap: Zero post-signature tracking
95% of conflicts over personal loans occur after the document is signed. Downloading a basic Word or PDF template leaves a crucial question unresolved: how do you prove that part of the sum was paid back 6 months later?
Untracked partial repayments
The borrower pays back in installments without receipts. A year later, no one agrees on the remaining balance.
The living ledger solution
On Dethique, every declared repayment is validated by the lender and the remaining balance is updated in real time on the server.
Taxation: What must be declared to authorities
Tax authorities regulate personal loans with clear guidelines:
The €5,000 threshold (Form No. 2062)
Any loan exceeding €5,000 must be declared to French tax authorities using Form 2062 (Cerfa 10142) during income tax filing.
Risk of reclassification as a gift
Without a dated written agreement and repayment proofs, tax authorities can treat the transfer as a disguised gift and apply gift taxes and penalties.
Frequently asked questions about debt acknowledgments
Is a notary mandatory?
No. For loans between individuals, a signed private agreement (with witnesses) is fully valid and sufficient in almost all cases.
What is the legal validity duration?
In French civil law (Article 2224 of the Civil Code), the limitation period for personal debts is 5 years from the agreed due date.
Why involve witnesses in an IOU?
Having 2 independent trusted witnesses proves mutual and free consent, giving superior legal and moral strength to the agreement.
