Why a written agreement matters
Loans between friends, relatives or business acquaintances often start with a handshake. Memories fade, circumstances change and heirs may not know the arrangement existed. A signed document turns an informal understanding into evidence that a court, tax authority or executor can recognise.
For the borrower, the agreement fixes the terms so the lender cannot demand early repayment without cause or change the interest later. For the lender, it proves the money was a loan rather than a gift, which affects both recovery rights and tax reporting.
Promissory note versus loan agreement
A promissory note is a short promise to pay, signed by the borrower. A loan agreement is fuller and signed by both parties, covering obligations, default and dispute resolution. Simple, small loans can rely on a note; larger or secured loans deserve a complete agreement.
Who should use a template
Templates suit straightforward unsecured loans between individuals who understand the terms. Secured loans on property, cross-border loans, loans to businesses or arrangements involving large sums or vulnerable people justify review by a lawyer, because local formalities may determine whether the document is enforceable.
Capacity and consent checks
Both parties must be adults with legal capacity, entering the agreement freely. Where an elderly or vulnerable person lends, independent advice protects everyone against later claims of undue influence. Recording that each party had the opportunity to seek advice strengthens the document.
Interest, tax and legal limits
Private lenders may charge interest, but usury laws in many jurisdictions cap rates even for personal loans. Charging nothing is often allowed, though tax rules may impute interest. In the United States, the IRS publishes Applicable Federal Rates monthly as reference minimums for loans between related parties.
US tax points to note in the agreement
Section 7872 of the Internal Revenue Code generally ignores gift loans of 10 000 dollars or less unless used to buy income-producing assets. Above that, forgone interest may count as a gift and imputed income. Documented unpaid loans may support a bad debt deduction.

Clauses for death or incapacity
The agreement can state whether the debt is forgiven on the lender's death or remains payable to the estate, and what happens if the borrower dies. Clarifying this avoids disputes among heirs and should align with the lender's will and estate plan.
Drafting and signing step by step
Following an orderly process produces a document both parties understand and can rely on. The aim is a contract that leaves no ambiguity about amount, timing or consequences, and that satisfies any formal requirements of the governing jurisdiction.
- Agree the amount, interest, schedule and purpose in conversation, then write them down.
- Fill in each template clause, adapting wording to local law and currency.
- Attach an amortisation schedule showing every payment and remaining balance.
- Have each party review the draft, ideally with independent advice for larger sums.
- Sign in the presence of a witness or notary if required or desired.
- Transfer the money by bank, referencing the agreement, and keep copies for both sides.
- Register any security, such as a mortgage or vehicle lien, with the relevant authority.
Records to keep for the life of the loan
Each party should retain the signed agreement, the schedule, bank records of the advance and every repayment, any amendments signed by both sides, and correspondence about missed payments. These records support tax filings and demonstrate good faith if the loan must be enforced.
Common gaps and red flags
- Omitting a final repayment date, which makes the loan look like a gift or an open-ended favour.
- Paying in cash without receipts, leaving no evidence of either advance or repayment.
- Setting an interest rate above the legal maximum, which can void interest or the whole contract.
- Using a downloaded template supplied by an online lender who then requests a stamp duty, notary or registration fee before transferring the loan; genuine private agreements do not require paying the lender anything up front.
- Changing terms verbally without a signed amendment.
Fake agreements used by scammers
Advance-fee fraudsters often send professional-looking loan contracts with seals and signatures to appear legitimate. The document then mentions a mandatory fee before disbursement. A real lender's contract never makes release of funds conditional on the borrower first paying the lender or its agent.
Private loan agreement questions
These answers respond to common questions from people formalising loans between individuals. Contract formalities and tax treatment depend on the governing law, so a local lawyer or tax adviser should confirm requirements for sizeable or secured arrangements.
Does a private loan agreement need to be notarised?
Usually not for validity, though some countries require notarisation for enforcement or for loans secured on property. Notarisation or independent witnessing still adds useful evidence that the signatures are genuine and that both parties signed willingly and knowingly.
Can the lender charge any interest rate?
No. Usury limits and consumer protection rules in many jurisdictions apply to private lenders too. Excessive interest may be unenforceable or even unlawful. The agreed rate should be checked against the cap where the borrower lives.
What if the borrower stops paying?
The lender should send a written reminder, then a formal demand under the default clause. If unresolved, small claims or civil court procedures allow recovery. A clear agreement and payment records make that process faster and cheaper.
Can an existing informal loan be documented later?
Yes. Parties can sign an agreement acknowledging the outstanding balance and setting future terms. Including the original transfer date and amount, plus any repayments already made, creates a coherent and verifiable record from that point forward.
