How to Write a Security Deposit Demand Letter

A good letter is short, factual, and easy to verify. It asks for the deposit or a clear explanation without turning the dispute into a fight.

TL;DR

State the rental, the deposit, the move-out facts, what you want, and how the landlord can respond. Keep the tone calm. Attach only useful proof. Send it in a way you can document. Then use your state page for the response window and next step.

Seven steps for the letter

Identify the rental. Name the property, landlord or manager, tenant, and lease dates.
State the deposit facts. Say what you paid and point to the record that proves it.
Describe the move-out record. Use the date, keys, forwarding address, photos, and messages you can support.
Ask for a specific result. Request the return of the deposit or a written itemized statement.
Use your state rule carefully. Refer to your state's statute only after checking the state page.
Keep the tone businesslike. Write as if a court clerk or mediator may read it later.
Choose trackable delivery. Certified mail can help create a record, and you can also keep email or portal proof.

What NOT to write

Do not threaten harm, harassment, public shaming, or illegal action.
Do not invent repair prices, dates, or conversations you cannot support.
Do not mix unrelated disputes into the same demand unless they explain the deposit record.
Do not cite a statute from another state or a sample letter you did not verify.

What happens after sending

Save the final letter, attachments, delivery record, and any reply. If the landlord responds, compare the reply to your documents. If there is no response, check your state page before choosing a follow-up letter, small claims, or legal help.

If the letter does not resolve the dispute, compare your escalation options. Review the glossary definition of a demand letter before drafting.

Pick your state

Use the state page for the response window, statute language, and local next steps that belong to your rental.
