ChatGPT Prompt for a Demand Letter

Write a pre-legal demand letter that's firm without being threatening — specific dollar amount, dates, contract reference, response deadline. For contractors, vendors, deposits, owed wages.

Updated May 2026.

The best ChatGPT prompt for a demand letter writes a firm-but-professional pre-legal letter to recover money owed — with a specific dollar amount, dates, contract or agreement reference, and a response deadline. It avoids threatening language while signaling you're serious about next steps.

The Prompt
You are a consumer protection attorney drafting a pre-legal demand letter for a non-attorney client. Your goal: firm enough to be taken seriously, not so aggressive that it kills any chance of voluntary payment.

WHO I'M WRITING TO (name + role + company): [PASTE]
WHAT I'M OWED (one sentence — what they did or failed to do): [PASTE]
SPECIFIC DOLLAR AMOUNT OWED: $[PASTE]
KEY DATES (when service rendered, when due, when promised, when ignored): [PASTE]
WRITTEN AGREEMENT OR REFERENCE (contract clause, invoice number, email date): [PASTE]
EVIDENCE I HAVE (attachments to mention): [PASTE]
WHAT I WANT (payment / refund / service completion / other): [PASTE]
RESPONSE DEADLINE I'M GIVING THEM (recommend 14–21 days): [PASTE]

HARD RULES:
1. Tone is professional and firm — NOT threatening. No “I will see you in court.”
2. State the demand in the first paragraph. The narrative goes after.
3. Reference specific dates, amounts, and contract terms. Vague demand letters are ignored.
4. End with a clear deadline AND a specific next step if the deadline passes (small claims, formal complaint, attorney involvement) — but stated as a fact, not a threat.
5. Banned phrases: I demand, I insist, I will not tolerate, this is unacceptable, ASAP, time is of the essence.
6. ADD A DISCLAIMER at the bottom: “This letter is not legal advice. For matters above small-claims-court limits or involving contract disputes, consult an attorney before sending.”

OUTPUT IN ORDER:
A. The full demand letter, formatted for mail or email.
B. A “certified mail + return receipt” recommendation if the amount is over $500 (yes/no plus why).
C. A list of the strongest pieces of evidence to attach.

How to Use This Prompt

  1. Copy the prompt and fill in the bracketed sections with your real details.
  2. Be specific. Vague input produces vague output — that's the whole point of the gates.
  3. Paste into ChatGPT, Claude, or Gemini and read the output before using it.
  4. Edit the draft in your own voice before sending or submitting. AI output is the scaffolding, not the final.

Example Output

Excerpt:

Re: Demand for payment — Invoice #2034, dated March 12, 2026

Dear Mr. Hartley,

I am writing to demand payment of $2,840 owed for landscaping services performed at 1422 Pine Street on March 12, 2026 and invoiced the same day under Invoice #2034. Under the terms of the signed estimate (attached, dated Feb 28, 2026), payment was due net 15. As of today, payment is 47 days overdue and three follow-up reminders (March 28, April 12, May 1) have gone unanswered.

I am requesting payment in full of $2,840 by June 8, 2026 (21 days from the date of this letter)...

This letter is not legal advice. For amounts above small-claims-court limits, consult an attorney before sending.

Tips to Get Better Results

  • Send it certified mail with return receipt for anything over $500. The receipt becomes evidence.
  • Keep a copy of everything you send and receive. Demand-letter cases often turn on the paper trail.
  • Be specific about dollar amounts and dates. “Approximately $1,000” weakens the whole letter.
  • For amounts above your state's small claims limit or for any contract dispute over a few thousand dollars, see an attorney before sending — this prompt drafts the letter, it doesn't replace legal counsel.
