The economic context continues to put pressure on household budgets in 2026. As banks and financial institutions become increasingly cautious with financing, more and more people are turning to personal loans between individuals to meet their needs.
Whether it is between friends or family, these “private loans” are often concluded informally, without any written contract, which makes it very difficult for the lender to prove the existence of the loan in case of disagreement. Here are the key legal tools that allow you to protect yourself while preserving your relationships.
Formalizing a Loan Between Individuals: Why It Is Essential
A loan between individuals may seem simple and based on trust, but in the event of non‑payment, a breakup, a divorce, or an inheritance, the absence of a written contract can have serious consequences. The judge will require proof of the loan and its terms. Without a proper document, you risk losing large sums or being unable to recover the money loaned.
To avoid this, the law offers several solutions: the authentic deed before a notary, the private agreement signed by both parties, or the debt acknowledgment drafted by the borrower. These tools give the loan legal value and clarify everyone’s obligations: amount, repayment schedule, interest rate, and purpose of the loan.
Whether you are lending €1,000 or €20,000, the logic remains the same: the more precise and complete the document, the easier it will be to enforce your rights if the relationship with the borrower deteriorates. Properly documenting a personal loan is not a sign of mistrust but a way to protect both parties.
Authentic Deed or Private Agreement: Which Legal Form to Choose?
The authentic deed is a written document executed before a notary. It has strong probative value and is difficult to challenge in court. It also allows, in certain cases, for direct enforcement (for example, wage garnishment) without having to initiate lengthy proceedings. This option is particularly recommended for large amounts or complex family situations.
The private agreement is a written contract signed directly between the lender and the borrower, without a notary. Although simpler and less expensive, it is nonetheless legally valid if it is properly drafted. The agreement must clearly identify the parties and detail all essential aspects of the loan.
In both cases, the following information should appear:
- Full identities of the parties (surname, first name, address, and, ideally, date of birth)
- Place and date of conclusion of the contract
- Exact amount loaned and means of transfer (bank transfer, cheque, etc.)
- Repayment terms (installments, due dates, possible grace periods)
- Applicable interest rate, if any, and the total cost of the loan
- Duration of the loan and, if relevant, its purpose (purchase, renovation, consolidation, etc.)
- A clear clause in which the borrower expressly declares having received the full loan amount
All parties must sign the contract, preceding their signatures with the phrase “Read and approved.” The document must be drafted in as many original copies as there are parties involved so that each person holds an original.
Concrete Example of a Loan Between Individuals
Imagine that you decide to lend €20,000 to your cousin, who is married under a community property regime. Legally, both spouses are concerned by the loan.
Three signatures will be required:
- Your signature as lender
- Your cousin’s signature as borrower
- The spouse’s signature, also bound by the commitment
You must then prepare three original copies of the contract so that each party can keep their own signed document. This precaution will make it easier to enforce the agreement in case of dispute.
Debt Acknowledgment: A Simple and Powerful Tool
Another way to formalize a personal loan between individuals is through a debt acknowledgment. This is a unilateral written document by which the borrower acknowledges owing a specific sum of money to the lender. Unlike an authentic deed, a debt acknowledgment does not necessarily require the intervention of a notary.
In principle, the acknowledgment should be written entirely by the borrower’s hand and kept by the lender until the loan has been fully repaid. This handwritten feature strengthens its probative value, as it clearly establishes the borrower’s intention and commitment.
If the acknowledgment is not fully handwritten (for example, typed and then printed), the borrower must personally add, in their own handwriting, a statement such as “good” or “approved,” followed by the amount in full words. This makes it more difficult for the borrower to dispute the amount or claim they did not understand the commitment.
Mandatory Mentions in a Debt Acknowledgment
To be effective, a debt acknowledgment must contain certain key elements. Even though the cause of the debt does not have to be specified, some mentions are indispensable for legal security.
- Date and place of drafting the acknowledgment
- Full identities and contact details of the lender and borrower
- Exact amount owed, preferably indicated in figures and in words
- Borrower’s handwritten phrase (“good for” or “approved for”) followed by the amount in words if the document is typed
- Borrower’s signature and, if applicable, the signature of any co‑borrower or spouse involved
The parties are free to add further clauses such as interest rate, repayment schedule, possible early repayment, or penalties in case of late payment. The more explicit the acknowledgment, the easier it will be to enforce.
Key Advantages of a Well-Structured Loan Between Individuals
Properly formalizing a personal loan between individuals does not only protect the lender; it also reassures the borrower thanks to clear, predictable terms. Below are the main strengths of adopting a professional approach to your private loan.
Stronger Legal Protection
Authentic deeds, private agreements, and debt acknowledgments provide solid proof of the loan. In case of conflict, you can rely on a clear, dated, and signed document rather than oral promises or informal messages, greatly increasing your chances of recovering the sums loaned.
Preserved Relationships
A clear written framework helps avoid misunderstandings between friends or family. Everyone knows the amount, repayments, and deadlines in advance, which limits frustration and tensions. Transparency protects both your finances and your personal relationships over time.
Flexibility and Clarity
Unlike standard bank products, loans between individuals can be tailored to your situation: customized duration, interest rate, or repayment rhythm. A solid contract turns this flexibility into a secure framework rather than a source of legal uncertainty in 2026.
Recommendations and Risks: What You Should Never Neglect
Legal formalities surrounding the drafting of an authentic deed, private agreement, or debt acknowledgment are not optional. If the required rules are not respected, the document may be reclassified by a judge or even declared null and void. In such a scenario, you will have great difficulty proving the existence and exact terms of the loan.
In practice, the judge might then base their decision only on partial evidence such as bank transfers, payment receipts, or email and message exchanges in which the borrower acknowledges the existence of a loan. These elements can help, but they rarely provide a complete and indisputable picture of the agreement.
To secure a personal loan between individuals in 2026, you should therefore:
- Always draft a written document, even for loans between close relatives
- Specify the amount, duration, and repayment terms with maximum precision
- Ensure that all relevant parties sign (borrower, spouse if applicable, co‑borrower)
- Keep original copies and proof of transfer of funds (bank statements, receipts)
- Seek professional advice for significant amounts or complex family situations
Formalizing your loan does not prevent you from being supportive; it simply ensures that your generosity is not turned against you. A clear contract is your best ally for making personal lending safe and sustainable.
