Security deposit demand letter
By Justin Winter · Updated August 18, 2026
The short answer
A deposit demand works when the deadline in it has a date behind it. Send it Certified with electronic Return Receipt, $14.99 all-in: USPS records when it was mailed and when it was signed for. Preview the exact pages free. Deposit rules vary by state; this template is not legal advice.
The math
The math on one certified letter.
| Option | Cost | Your time |
|---|---|---|
| paperplane, Certified + Return Receipt | $14.99, all in | About two minutes |
| At the counter | USPS fees, plus printing, an envelope and the trip | About ten minutes at the counter, plus the drive and the line |
USPS charges the same fees whoever hands the letter over. The difference is the trip, the form and the slip you keep for a year.
The math
What the letter costs against what it asks for.
If your deposit is $1,200, the demand costs $14.99: about 1% of what you are asking for. Use your own amount.
Use our template to state the essentials: the rental address, your move-out date, the deposit amount, the date you moved out, and the statutory deadline. Keep it factual and unemotional — a demand letter works because it documents the facts, not because it escalates.
What certified mail adds

- A private tracking link you can keep for your records and share with your lawyer.
How it works
- Open the template, edit the bracketed fields, and confirm the recipient address.
- Pay $14.99 (Certified with Return Receipt) or $12.99 (Certified).
- The letter is printed and handed to USPS the next business day.
- Your document file is permanently deleted 30 days after delivery.

Questions before you send
Why not go to the post office myself?
You can, and if your time is free it costs less. USPS charges the same fees whoever hands the letter over; paperplane does not replace the post office, it replaces the trip. The mailing record comes from USPS, not from us. $12.99 covers the printing, the envelope, PS Form 3800, a USPS address check before you pay and a handoff the next business day. For a letter you already know how to send, the counter is a fine choice.
What if they refuse the letter?
USPS tracking records what happened to it, including refused or unclaimed. You still have the mailing record. Rules on what that means vary, so check with your court or an attorney if a deadline depends on it.
If something goes wrong, do I pay?
If we cannot mail the letter, the hold on your card is released and you are not charged. If a letter fails after your card is charged, you are refunded automatically and in full.
Should I send a deposit demand by certified mail?
Yes. Certified Mail with electronic Return Receipt gives you a signed USPS record that the landlord received your demand, which matters if you later sue for the deposit under state law.
What should the letter include?
The rental address, your move-out date, the deposit amount, the statutory deadline, and a clear date by which you want the refund. Our template pre-fills all of that for you to edit.
How much does certified mail cost?
Certified Mail with electronic Return Receipt is $14.99 all-in, including printing, the envelope, and USPS postage and tracking.
Is this legal advice?
No — it is a tool and a template, not legal advice. State laws on deposit return timelines vary; you may want to confirm the deadline for your state.
