Send a security deposit demand letter

If your security deposit hasn't come back, a clear written request sent with proof of delivery is usually the next step. Your agent can draft it in a minute; we mail it by Certified Mail with a return receipt.

Common questions

How long does a landlord have to return a deposit?

It depends on your state, and many states set a specific deadline. Check your state's rules or a tenant resource before you send.

Why use a return receipt?

It comes back with the recipient's signature, which is strong proof that your landlord received the request.

Do you give legal advice?

No. We print and mail what you or your agent writes. For advice about your situation, contact a tenant organization or an attorney.

Sendpaper prints and mails what you or your agent writes. We're not a law firm or tax preparer and don't give legal or tax advice; for deadlines and the right address, check the notice itself, the agency, or a professional.
