Security Deposit Demand Letter: Free Template and How to Send It
A free security deposit demand letter template with instructions: what to include, how to send it by certified mail, and what to do if it's ignored.
In this guide
When your state’s deadline to return a security deposit has passed and your landlord has gone quiet, the next move is a written demand letter. It is short, it is free, and it works more often than you might expect — because it converts a silent standoff into a documented legal dispute the landlord can lose.
This guide gives you a complete template, tells you how to fill in each part, and explains how to send it so it counts as evidence.
Before you send it: confirm your state’s deadline has actually passed using our state-by-state deadline table, and re-read your lease for any notice terms. A demand letter sent too early is easy for a landlord to brush off.
What a demand letter does
A security deposit demand letter puts three facts in writing: you are owed money, the legal deadline to return it has passed, and you will use small claims court if it is not paid by a specific date. Judges expect tenants to have made a written demand before filing, and the letter itself — plus the certified-mail receipt — becomes some of your strongest evidence.
The template
Copy the letter below and replace every bracketed item with your own details. Keep it factual and unemotional — the letter’s power comes from dates and facts, not anger.

RE: Return of security deposit for [rental address, unit number]
Dear [Landlord's name],
I was the tenant at [rental address] under a lease that ended on
[lease end date]. I moved out and returned the keys on [move-out date],
and I provided my forwarding address on [date you gave it].
I paid a security deposit of $[amount] on [date paid]. As of the date
of this letter, [number] days have passed since my tenancy ended, and I
have not received my deposit or an itemized statement of deductions.
[State name] law requires a landlord to return a tenant's security
deposit or provide an itemized statement of deductions within the
statutory deadline, which has now passed.
Please send the full deposit of $[amount] to my address above no later
than [date 10–14 days out]. If I do not receive it by that date, I am
prepared to file a claim in small claims court seeking the deposit plus
any additional damages, interest, and costs the law allows.
I have kept a copy of this letter, my lease, my payment records, and
dated photographs of the unit at move-out.
Sincerely,
[Signature]
[Your printed name]How to fill it in
- Dates are the spine of the letter. Lease end, move-out, forwarding address, deposit payment — a judge can reconstruct the whole timeline from these four dates, so get them right and keep proof of each.
- Name the amount precisely. Use the exact deposit figure from your lease or receipt. If the landlord returned part of it, demand the remaining balance and say so.
- Don’t cite a statute number unless you’re sure. The template’s “statutory deadline” language works in every state. If you want to cite your state’s statute, copy it from the official source linked in our deadline table — never from memory.
- Keep the threat conditional and calm. “I am prepared to file” is enough. Threats beyond small claims court — or anything that reads as harassment — only weaken your position.
How to send it
- Print two copies — one to send, one to keep.
- Send by certified mail, return receipt requested, to the address your lease or state law designates for notices. The green-card receipt (or electronic equivalent) proves delivery.
- Optionally email a copy the same day with the subject “Security deposit demand — [rental address]” so there is a timestamped digital trail too.
- Calendar the response date. The day after your stated deadline passes, you are free to file in small claims court.
If the letter is ignored
Small claims court is the designed next step — low filing fees, simplified procedure, and in most states no lawyer needed (some states don’t even allow them in small claims). Bring your lease, payment proof, move-out photos, the demand letter, and the certified-mail receipt. Our security deposit basics guide covers what to expect, and in many states a judge can award two or three times the deposit when a landlord withheld it in bad faith.
When to get help
If the amount is large, the landlord has counter-claimed damage you dispute, or you simply want someone to review your case first, free help exists: legal aid offices handle landlord-tenant disputes routinely, and many courts have self-help centers that assist with small claims filings.

Frequently asked questions
Does a demand letter actually work?
Often, yes. A written demand shows the landlord you know the deadline passed, creates a paper trail a judge can see, and signals you are prepared to file in small claims court. Many landlords return deposits after receiving one because defending a small claims case costs more than the deposit — especially in states that allow multiple damages for bad-faith withholding.
Should I send the letter by certified mail?
Yes, certified mail with return receipt requested is the standard method, because it proves the landlord received your demand and when. Keep the receipt and a copy of the letter. Email can supplement the mailed copy but should not replace it unless your lease specifically makes email an accepted notice method.
How long should I give the landlord to respond?
Ten to fourteen days is a common, reasonable window. The law in your state may not require you to give extra time at all once the statutory deadline has passed, but a firm, dated response window makes your letter stronger evidence and shows a judge you acted reasonably.
What if my landlord ignores the demand letter?
The usual next step is small claims court, which is designed for people without lawyers and has low filing fees. Bring your lease, move-out evidence, the demand letter, and the certified mail receipt. In many states a judge can award extra damages if the landlord withheld the deposit in bad faith.
