How to prepare and send a demand letter
A demand letter can be an early formal step when someone owes you money or broke an agreement. This guide covers what to write, how to send it, and what to do after the response date passes. Petty can help you organize the letter and handle sending if you'd prefer not to do it yourself.
Petty is a self-help tool, not a law firm. For complex disputes, consult an attorney.
What is a demand letter?
A demand letter is a written notice you send before filing a lawsuit. It tells the other party what happened, what you believe they owe you, and what you want them to do by a specific date. It's not a court document and it doesn't require a lawyer to write.
The main purpose is to give the other party a chance to resolve things without court. A formal written notice can make your request and proposed next steps clear, but it does not have legal force on its own or guarantee a response.
Some courts ask whether you gave the other party an opportunity to respond before filing. A documented delivery record can help show you made that attempt. Whether and how your specific court weighs this depends on its own rules, so verify what's expected in your jurisdiction.
What to include in a demand letter
Who you are and who you're writing to
Full names and addresses for both parties. If you're writing to a business, use the legal entity name. Look it up on your state's business registry if you're not sure.
What happened and when
A factual account: the dates, the agreement, the breach. Stick to what's relevant to the money or obligation you're claiming. The key facts are enough; a full narrative usually isn't necessary.
What you're owed
The specific dollar amount, or the specific action you're requesting (return an item, complete the work). Vague demands are easier to ignore. Be precise.
A response date
Set a specific calendar date, not just a vague timeframe. What's reasonable depends on your contract, any applicable statute, urgency, delivery time, and the rules of the court you might use. Check those before picking a date.
The basis for your claim
Reference the contract clause that was breached, or the relevant law if you know it. For security deposits and wages, state-level statutes often apply. Verify citations against your state's current code before sending.
What you'll do next
State the consequence of non-response, such as consulting an attorney or filing in small claims court. Don't threaten things you can't or won't do. An idle threat signals that you're bluffing.
How to choose a delivery method
Certified mail with return receipt
USPS certified mail gives you a tracking number and a card signed by the recipient (or their household) confirming delivery. That delivery record is difficult to dispute. It's worth the extra few dollars for any dispute that might escalate, though you should also confirm whether the court you might use has specific notice requirements.
Fast and low cost. But email delivery is easier to contest (spam folders, changed addresses, "I never saw it"). If you use email, request a read receipt and save a screenshot of the sent message with its timestamp. Courts vary in how they treat email notice, so check the rules of the court you might file in. If there's any doubt, send a physical copy as well.
Hand delivery or process server
Hand delivery works if you have a witness or get a signature. A process server creates a formal record. These can be useful when you expect the other party to contest receipt of a mailed letter. Both are more logistically involved than certified mail, and costs vary.
What evidence to keep
From the moment you send the letter, treat this like a case file. Keep everything.
- A copy of the demand letter you sent
- The USPS tracking number and the signed return receipt card (if sent by certified mail)
- A screenshot of any email you sent, with timestamp
- The date you sent the letter and the response deadline you set
- Any response you receive (written, text, or email)
- The original documents supporting your claim: contracts, invoices, receipts, texts, photos
- Any bank records showing payment or non-payment
If the dispute proceeds to court, this becomes your documentation file. What you can use and how depends on the rules of the specific court. Organize it now so you're not scrambling later.
Choosing a response date
There's no single deadline that applies to all demand letters. What's reasonable depends on several things: any deadline set by your contract, whether a statute requires a specific notice period, how urgent the situation is, how long delivery will take, and the rules of the court you might use.
A range of 14 to 30 days is a common planning example for straightforward disputes, but treat it only as a starting point. For some dispute types (security deposits, wage claims, and others), your state may have statutory notice requirements that should control your deadline rather than any general rule of thumb.
Set a specific calendar date in the letter rather than a vague window like "within 30 days." A specific date is clearer and leaves less room for misinterpretation. Before you settle on one, check whether any statute or contract term dictates a different period for your situation.
Common mistakes
Writing emotionally instead of factually
A letter full of frustration is easier to dismiss. A calm, factual tone is harder to argue with. State what happened; don't editorialize.
Being vague about what you want
"Compensate me fairly" is not a demand. State the exact dollar amount or the specific action you're requesting. Vague demands are easier to ignore.
Not setting a deadline
Without a response date, the letter has no urgency. The other party has no reason to act, and you have no clear trigger for next steps.
Threatening things you won't do
Don't threaten criminal charges for a civil matter, or claim you'll involve parties you have no standing to involve. Empty threats signal that you're bluffing.
Sending it in a way you can't document
If you can't show a record of delivery later, the letter's value as documentation is limited. Certified mail or another verifiable method solves this.
Not keeping a copy
Keep a copy of every version of every document you send. If the dispute proceeds, you'll need to show what you actually sent.
What to do after the response date
When the deadline passes, you have three realistic options.
Send a follow-up notice. Sometimes people miss the first letter or need a second prompt. A follow-up that references the first letter and sets a shorter new deadline occasionally prompts a response.
File in small claims court. If the amount is under your state's filing limit, small claims is often the most accessible path. Your documented delivery record can be relevant to your case, depending on the court's rules. Filing fees and claim limits vary by state, so check your specific court's requirements.
Consult an attorney. For larger amounts or more complex situations, a lawyer can assess whether you have a viable claim and what your options are. Your prior documentation of the dispute can be useful in that conversation.
One thing that matters regardless of which path you take: every state has a statute of limitations for filing legal claims. The length varies by state and dispute type. Missing it can extinguish your right to sue. Verify the deadline that applies to your specific claim before you run out of time.
Step-by-step: preparing and sending a demand letter
Five steps from deciding to write to knowing what comes next.
Gather your facts and documents
Collect any contracts, invoices, receipts, texts, or emails that support your claim. Know the amount you're owed and the dates that matter. You can't write a credible demand letter without this foundation.
Write the letter
State who you are, who you're writing to, what happened, what you're owed, and what you want the other party to do. Set a specific response date. Keep the tone firm and factual, and avoid threats or emotional language.
Choose a delivery method
Certified mail with return receipt creates a postal record. Email works but is easier to dispute. Hand delivery requires a witness. The right method depends on what you may need to prove later and the rules of the relevant court.
Send and document everything
Keep a copy of the letter, the tracking number, and the signed receipt. If you emailed, save the sent message. This documentation matters if the dispute goes further.
Wait for the response date, then decide next steps
If the deadline passes with no response or a refusal, you have a documented record of your attempt to resolve it. At that point, small claims court or an attorney consultation may be appropriate next steps depending on your situation.

Dispute types Petty supports
Petty covers common self-help dispute categories. If your situation is unusual or involves large sums, consider consulting an attorney as well.
Unpaid debts
Personal loans, unpaid invoices, money lent and not returned. The letter lays out what's owed and sets a clear deadline.
Late or missing paychecks
Wages not paid on time, withheld commissions, final checks that never arrived. A written demand creates a paper trail before you escalate.
Security deposits
Landlords have legal deadlines to return deposits in many states. A demand letter states what you're owed and references the timeline your state sets. Verify the specific rules in your jurisdiction.
Contractor disputes
Incomplete work, shoddy repairs, or a contractor who took your deposit and disappeared. The letter documents what went wrong and what you're asking for.
Breach of contract
Any agreement that wasn't honored: business deals, service contracts, written or verbal. The letter identifies the specific failure and the remedy you're seeking.
Damaged property
Compensation for property damaged by a neighbor, business, or during a service. Include your repair estimate or replacement cost.
Subscription refunds
Unauthorized renewals, charges for services not delivered, hidden fees. Consumer protection laws may apply depending on your state; check what applies to your situation.

Frequently asked questions
What is a demand letter?
A demand letter is a written notice you send to someone who owes you money or has wronged you in a way that causes financial loss. It states what happened, what you're owed, and what you want the other party to do by a specific date. It's not a court filing. It's a formal request that creates a documented record of your attempt to resolve the dispute before pursuing legal options. Whether a court finds that record meaningful depends on the specific court and jurisdiction, so check the rules that apply to your situation.
What should a demand letter include?
A solid demand letter covers six things: (1) who you are and who you're writing to; (2) a factual description of what happened and when; (3) the specific amount you're claiming or the action you're requesting; (4) a reasonable response date (14 to 30 days is a common planning range, but what's appropriate depends on your contract, any applicable statute, urgency, delivery time, and local court rules); (5) any relevant contract terms, statutory rights, or legal basis for your claim; and (6) what you plan to do if there's no response, such as consulting an attorney or filing in small claims court. Keep the tone firm and factual. Emotional language tends to undermine credibility.
How do I choose a delivery method for my demand letter?
The right delivery method depends on what you may need to prove later and the rules of the court you might use. Certified mail with USPS Return Receipt gives you a postal record (a signed card confirming delivery) that is hard to dispute. Email is convenient but the other party can claim they never received it or that it went to spam. Hand delivery works if you have a witness or get a signature. Whatever method you choose, keep copies of everything and check whether the court you might file in has specific delivery requirements.
Is certified mail better than email for a demand letter?
Certified mail creates a verifiable delivery record through USPS, which is generally harder to dispute than email. Email is faster and cheaper, but delivery is easier to contest, and courts vary in how they treat it. Some courts have specific notice requirements that may favor one method over another. Before choosing, check the rules of the court you might file in, and consider sending both if you're unsure.
What evidence should I keep after sending a demand letter?
Keep everything: a copy of the demand letter you sent, the USPS tracking number and signed return receipt card if applicable, a screenshot of any email you sent with its timestamp, the date you sent the letter and the response deadline you set, any response you receive (written, text, or email), and the original documents supporting your claim (contracts, invoices, receipts, texts, photos, bank records). If the dispute proceeds further, this becomes your documentation file. What you can actually use in court depends on the rules of that court.
How do I choose a reasonable response date?
There's no single deadline that applies to all demand letters. What's reasonable depends on several factors: any deadline set by your contract, whether a statute requires a specific notice period, how urgent the situation is, how long delivery will take, and the rules of the court you might use. A range of 14 to 30 days is a common planning example for straightforward disputes, but you should treat that only as a starting point. For some dispute types (security deposits, wage claims, and others), your state may have statutory notice requirements that should control your deadline. Check what applies to your specific situation before settling on a date.
What are the most common mistakes people make with demand letters?
A few come up repeatedly. Writing emotionally instead of factually: a letter full of frustration is easier to dismiss. Being vague about the amount or the remedy you're seeking. Not setting a specific deadline. Threatening things you can't actually do (such as threatening criminal charges for a civil matter). Sending it in a way you can't document later. Not keeping copies. Another common one: including too much, with long backstories and every grievance. Focus on the facts that matter to this specific claim.
What should I do after the response date passes?
If the deadline passes with no response or a refusal, you have a few options. You can send a follow-up notice, referencing the first and stating a shorter new deadline. You can consult an attorney to assess your options, especially for larger or more complex claims. Or you can file in small claims court if your amount falls under your state's limit, using your documentation as part of your case. One thing that matters regardless of which path you take: every state has a deadline (statute of limitations) for filing legal claims, and it varies by dispute type and state. Missing it can extinguish your right to sue. Verify the deadline that applies to your claim.
What does Petty do, exactly?
Petty is a self-help preparation tool. You answer questions about your dispute, and the tool organizes your information into a structured demand letter with relevant state context included. It also offers an optional certified mail sending service so you don't have to go to the post office yourself. Petty is not a law firm and does not provide legal advice or attorney representation.

Does Petty work in all 50 states?
Yes, Petty generates demand letters for disputes in all 50 states and includes state context based on your location and dispute type. Laws change and vary in ways that automated tools don't always capture in real time, so if your letter cites specific statutes, verify them against your state's current code before sending, especially for anything high-stakes.
What happens if the other party ignores my demand letter?
If the deadline passes with no response, your documented record of having sent the letter can be relevant to next steps, depending on the court and jurisdiction. At that point, you might file in small claims court (if your amount falls under your state's filing limit), consult an attorney, or send a follow-up notice. Petty can also help you organize information for court forms if you decide to file. The letter won't guarantee a settlement, but it gives you a documented starting point. Whether and how a court treats it depends on that court's rules.
