When someone owes you money and stops returning your calls, a written demand letter is the next step. It creates a formal paper trail, signals you are serious about collecting, and is the evidence a small claims court expects to see before awarding a judgment. This page provides real sample letters for two of the most common scenarios, with notes explaining what each section accomplishes.
For a custom letter built around your specific situation, use the free debt collection letter generator — it takes about five minutes and no account is required.
Sample 1: Personal loan — friend or family member
This situation is common and uncomfortable. You lent money to someone you trusted and they have stopped repaying. The letter below balances firmness with professionalism.

RE: DEMAND FOR REPAYMENT — Personal Loan of $3,500
Dear Daniel,
[State the loan plainly — date, amount, terms]
On November 8, 2025, I loaned you $3,500 to help cover your moving expenses. We agreed, over text message on November 7, 2025, that you would repay the full amount in monthly installments of $350 beginning January 1, 2026, with all payments completed by October 1, 2026.
[Document what has been repaid]
To date, you have made two payments of $350 each, on January 3 and February 11, 2026, for a total of $700. No payment has been received since February.
[State the current balance and what you are demanding]
The outstanding balance on this loan is $2,800. I have reached out by text message on April 2, April 19, May 7, and June 1, 2026, without receiving a response or a payment.
I am formally demanding repayment of $2,800 in full no later than June 24, 2026. Payment may be made by Venmo (@robert-chen-pdx) or by cashier’s check mailed to the address above. If you cannot pay the full amount by that date, please contact me before June 24 to discuss a written repayment plan.
[Consequence — specific and credible]
If I do not receive payment or hear from you by June 24, 2026, I will file a claim against you in Multnomah County Small Claims Court to recover the $2,800 balance plus court costs and any interest allowed under Oregon law.
I would prefer to settle this without involving the court. Please respond by June 24.
Sincerely,
Robert Chen
Sample 2: Business-to-business unpaid balance
A customer or client owes a balance not tied to a specific invoice — for example, work billed on a running account with outstanding charges.

RE: DEMAND FOR PAYMENT — Outstanding Balance of $4,150
Dear Mr. Marsh,
[Reference the business relationship and services rendered]
Clean Slate Bookkeeping LLC has provided monthly bookkeeping services to Evergreen Landscape Co. under our agreement dated January 15, 2025. Services have been rendered continuously from February through May 2026.
[State the balance and aging clearly]
Invoices for February ($950), March ($950), April ($1,150, reflecting the payroll processing added per your request), and May ($1,100) remain unpaid, for a total outstanding balance of $4,150. Copies of these invoices are enclosed. The oldest balance (February) is now 119 days past due.
[Prior collection attempts]
We have sent three payment reminders — on April 10, May 1, and May 28, 2026 — and have left two voicemails for your accounts-payable contact on May 15 and June 2. We have not received payment or a response.
[The demand]
We are formally demanding payment of $4,150 in full no later than June 24, 2026. Payment may be made by ACH transfer (instructions on our invoices), business check, or credit card by calling our billing line.
[Consequence — name the next steps]
If payment is not received by June 24, 2026, we will pursue all available remedies, including suspending all services, referring the account to a collection agency, and filing a claim in small claims court for the full balance plus court costs and late fees as provided in our agreement.
We value our working relationship and hope to resolve this promptly.
Sincerely,
Lisa Nguyen

What makes these letters work
Specific amounts with a paper trail. Both letters name exact dollar figures and reference prior communications with dates. Specific beats vague in every court.
Prior collection attempts documented. The letters note how many times the sender reached out and when. This matters — courts look for evidence you tried to resolve things informally.
A firm but reasonable deadline. Both use a 14-day window, which is standard. Short enough to maintain pressure; long enough to be credible.
Realistic next steps named. Small claims court, collection agency, and service suspension are all things the sender can and would do. Naming them makes the consequence tangible.

What evidence do you need to collect a debt?
The stronger your documentation, the higher your chance of success:
- Written loan agreement or promissory note — strongest
- Bank transfer, Venmo, PayPal, or Zelle records showing money changed hands
- Text messages or emails acknowledging the debt or promising repayment
- Signed invoices, contracts, or estimates for business debts
- Payment records showing partial repayments (which confirm the debt’s existence)
No written contract? You can still often collect. Courts evaluate whether a debt existed based on all evidence, including communication records and payment history.
Frequently asked questions
Does the Fair Debt Collection Practices Act (FDCPA) apply to me?
The FDCPA generally applies to third-party debt collectors — agencies hired to collect someone else’s debt. If you are collecting a debt owed directly to you, the FDCPA typically does not restrict your letters. That said, avoid harassment, false statements, and threats of criminal action regardless.
Can I add interest to the amount owed?
You can include interest if (a) your agreement specified an interest rate, or (b) your state’s law provides a statutory interest rate for unpaid debts. Do not invent a rate. If you are unsure, demand the principal and note that you will seek any interest the law allows.
What is the statute of limitations on debt?
It varies by state and by whether the debt is based on a written or oral agreement — typically three to six years from the date the debt became due. Once the statute of limitations expires, you lose the right to sue. Check your state’s rules and act well before the deadline.
Should I offer a payment plan?
If the debtor cannot realistically pay in full by your deadline, offering a written payment plan in the letter is reasonable. Get any plan signed. A missed payment on a written plan gives you cleaner grounds to proceed directly to court.
