Demand Letter for a Personal Loan Repayment

Money lent to a friend or family member sits in an uncomfortable gap: too real to forget, too personal to sue over without dread. A demand letter is how you take the ambiguity out. It restates the loan as a loan, names the amount and the history, and sets a deadline, while remaining civil enough to preserve what is left of the relationship.

Even purely verbal loans are enforceable in most situations; texts, transfers, and partial repayments all prove the deal existed. Your letter should assemble that evidence into one place.

[Your Full Name] [Your Street Address] [City, State ZIP] [Date] [Recipient's Full Name] [Recipient's Street Address] [City, State ZIP] RE: Formal Demand for Loan Repayment Dear [Recipient's Full Name]: This letter is a formal demand for payment of $[amount, e.g. 3,000.00], which you owe me for repayment of the personal loan I made to you on [date]. The relevant facts are straightforward. On [date], I lent you $[amount] by [method, e.g. bank transfer], which you agreed to repay by [date or schedule]. You have repaid $[amount repaid] to date. Your messages of [date] acknowledge the outstanding balance. The remaining balance of $[amount] is now past due. Demand is hereby made for payment in full of $[amount, e.g. 3,000.00] within 14 days of your receipt of this letter. Payment may be made as follows: [how to pay, e.g. bank transfer or check]. If payment is not received by that deadline, I intend to pursue the remedies available to me, which may include filing a claim in court and seeking recovery of costs where permitted. A judgment can affect your credit and can be enforced against wages and bank accounts. None of that is necessary if you simply resolve this now. This letter is written without waiver of any rights or remedies, all of which are expressly reserved. Sincerely, [Your Full Name]

Common questions

We never wrote anything down. Can I still demand repayment?

Yes. Verbal agreements to repay money are generally enforceable, and your bank transfer, their texts about paying you back, and any partial payments are all evidence. The letter itself often produces a written acknowledgment when they reply.

They say it was a gift. Now what?

Point to the repayment evidence: the schedule you discussed, the partial payments, the messages promising to pay. People do not make payments on gifts.

Is suing family worth it?

That is a personal call. The letter frequently resolves it without a filing, precisely because it shows you are willing to file. Many people find the relationship was already damaged by the unpaid debt, not by the letter.
