Security deposit demand letter
By Justin Winter · Updated August 18, 2026
You can send a security deposit demand letter online in about two minutes: we typeset your letter, print it, and mail it USPS Certified with electronic Return Receipt (court-ready proof of delivery) for $14.99 all-in.
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
- USPS tracking at every scan along the route.
- Electronic Return Receipt — a court-admissible signature record proving the landlord received it.
- 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 prints the next business day.
- Your document file is permanently deleted 30 days after delivery.
We screen content for fraud and threats only — a lawful demand for a deposit refund is fine. This template is a tool, not legal advice; deposit laws vary by state, so confirm your state's deadline and remedies.

Common questions
Should I send a deposit demand by certified mail?
Yes. Certified Mail with electronic Return Receipt gives you court-admissible proof 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.
