How to write a demand letter for a security deposit

What the letter should contain

• The deposit amount, the rental address, and the date you moved out.
• The state statute and the deadline it sets for returning the deposit.
• A clear request: return the deposit, or provide an itemized statement with receipts.
• A reply deadline, and what you will consider doing if it passes.
• Your name, and a mailing address or email for the response.

How to send it

Send it by a method that produces proof — certified mail with a return receipt is the common choice, and keeping a copy plus the receipt is what makes the letter worth writing. A letter you cannot prove was sent is much weaker than one you can.

A helpful discipline is to keep the tone flat and factual. The letter is evidence, not persuasion; anything that reads as a threat can hurt rather than help.

Blank beats filled-in

The paid guide ships a blank template with bracketed fields rather than a pre-filled letter, and that is deliberate: completing the specifics yourself keeps the letter your own statement of your own facts. We supply the structure and the statutory references; you supply the facts.

Common questions

Can I just text or email the demand instead?

A message can help, but written correspondence with proof of sending and delivery is stronger evidence. Where your state requires a written forwarding address or a certified notice, only the proper form will do.

Should I mention small claims court in the letter?

Stating factually that you will consider filing if the deadline passes is normal. Keep it factual and avoid anything that reads as intimidation — the letter may be read later by someone other than the landlord.
