Write a complaint letter with AI
Pick the situation and describe what happened. The AI drafts a formal complaint letter, the step before court: to whom, from whom, the facts, the demands and the deadline. Checking the document before sending is up to you and a lawyer.
TryChat is not a lawyer. We help you draft the document and do not give legal advice. Have it checked by a professional.
Prompt sent to the chat: «Draft a formal complaint letter, the kind sent before going to court, from a buyer to a shop, asking for a refund for a faulty product.

Formal complaint
On 2 October 2026 I bought a vacuum cleaner [model] in your shop for 18,990 roubles, receipt No. [number]. Ten days later it stopped switching on.
- Refund the 18,990 roubles paid for the product.
- If needed, carry out a quality check in my presence.
Deadline: please reply in writing within the period set by law. Otherwise I reserve the right to take the matter to court.
Enclosures: a copy of the receipt, photos and a description of the fault. Date, signature.
TryChat is not a lawyer: the AI prepares a draft. Have the document checked by a professional, especially if a large sum or a court case is involved.
How to write a complaint letter: eight required points
The AI puts these points in order itself. Your job is to give the facts and check that everything is there.
To whom
The company’s full name or the sole trader’s name and address – from the receipt, the contract or the seller’s page.
From whom
Your name, address and phone: the reply will come to them.
What happened
The facts by date: what you bought or ordered, when, for how much, what went wrong.
Documents
The contract, receipt, order or request number. Without them a complaint is easier to ignore.
Demand
One or two specific ones: a refund, a replacement, fixing the defects, a payment.
Amount
An exact figure; if you claim a penalty, attach the calculation separately.
Deadline and consequences
The legal deadline for a reply and what you will do next: an inspectorate, court.
Enclosures, date, signature
A list of the copies you attach. Keep the originals.
Deadlines by situation, in general terms
Each situation has its own law and its own deadlines. Here is where to start.
- A product from a shop or a marketplace
- What people usually demand: A refund, a replacement, a repair
- About the deadlines: The seller’s deadlines for a reply are set by consumer protection law and depend on the demand and on whether a quality check is needed.
- A service or repair work
- What people usually demand: Fixing the defects, a lower price, a refund
- About the deadlines: Deadlines depend on the demand and on what the contract says. Read the contract first.
- A property developer
- What people usually demand: A penalty for delay, the handover of the flat
- About the deadlines: The reply deadline is often written into the purchase agreement itself; the penalty is calculated by law.
- Building management
- What people usually demand: Carrying out the work, a recalculation
- About the deadlines: Deadlines for replying to residents are set by housing regulations; log every request with its number.
- An employer
- What people usually demand: Paying the settlement and compensation
- About the deadlines: Deadlines for the final settlement are set by labour law; late payment entitles you to compensation.
We do not give exact deadlines in days here: they depend on the demand, the contract and the version of the law. Ask the AI to name the provision it relies on, and check it against the current text of the law or with a lawyer.
How to send a complaint so they cannot say they never got it
A complaint only works if you can prove it was received. Keep a copy for yourself.
- 1
In person
Two copies: hand one over and ask for an acknowledgement on the other – date, signature, the recipient’s position. If they refuse to sign, send it by post.
- 2
By registered post
With an itemised list of the enclosures and a signed delivery confirmation, so you have proof of exactly what was sent and when. Keep the receipt and the list.
- 3
Electronically
Through the seller’s account on the marketplace or to the email address in the contract – if the contract or the marketplace rules allow it. Take screenshots.
Replying to a complaint, reviewing a contract, a statement of claim
Reply to a complaint
Received a complaint from a client? The AI writes a polite, formal reply: what you accept, what you offer, which documents are needed. General rules of business correspondence are on the business letter page.
Review a contract
Paste the contract text, and the AI finds the clauses on penalties, deadlines and termination and explains in plain words what to watch out for. Whether to sign is up to you and a lawyer.
Statement of claim
If the complaint goes unanswered, the next step is court. The AI suggests the structure and enclosures, but a statement of claim is best prepared with a lawyer.
When to go straight to a lawyer
The AI will not replace a lawyer if:
- The amount in dispute is large and the other side has lawyers.
- You have received a complaint or a lawsuit and the clock on your reply is already running.
- It is a dispute with a developer over a penalty or defects in the flat.
- You were dismissed and believe it was unlawful.
- You need to defend yourself as well as make demands: counterclaims, contractual penalties.
- You are not sure which law applies to your situation.
The AI draft is still useful: it is easier for a lawyer to check a finished text with facts and dates than to piece the story together from scratch.

FAQ
Is writing a complaint letter with AI free?
Yes. Complaints, replies to complaints and contract reviews are text requests, included in the Starter plan with 30 units of energy.
Does a complaint written by AI have legal force?
A complaint’s force comes not from who wrote it but from its content and proof of delivery: the right recipient, the facts, the demands, your signature and proof it was sent. TryChat is not a lawyer – have the document checked by a professional.
How do I write a complaint asking for a refund for a product?
Pick “Faulty product” or “Marketplace”, enter what you bought, when and for how much, and what broke. The AI states the refund demand and lists the documents to attach.
Does the AI know the exact deadlines and legal provisions?
It names the provisions usually cited, but it can be wrong or rely on an outdated version. Check the provisions and deadlines against the current text of the law.
Can I send a complaint by email?
Yes, if the contract or the marketplace rules allow it. The most reliable ways are in person with an acknowledgement or by registered post with a list of the enclosures.
I have received a complaint. Can you help me reply?
Yes: click “Reply to a complaint” and paste its text. If the complaint demands a large sum or threatens court, show the reply to a lawyer before sending it.
Can AI review a contract?
Yes: paste the text, and the AI highlights the risky clauses and explains them in plain words. It does not replace a legal review, but it helps you know what to ask a lawyer.
