Suing a landlord in small claims court for a security deposit

Updated October 29, 2026

The short answer

If a demand letter doesn't get your deposit back, you can sue the landlord in small claims court, usually in the county where the rental is located. Small claims is designed for people without lawyers, filing fees are modest, and you can ask for the deposit plus any penalty your state allows for bad-faith withholding. Bring the lease, proof of payment, photos, the letters you sent and the certified mail receipts.

Before you file

Send a demand letter and, if needed, a final notice. Judges look favourably on renters who tried to resolve the dispute first, and some courts expect a written demand.

Where to file

File in the small claims court for the county where the rental property is, unless your court's rules say otherwise. Most courts have a small claims self-help page with the forms, filing fee and dollar limit. Check your local court's website.

What to bring

  • The lease and proof of the deposit paid
  • Move-in and move-out photos or video with dates
  • Any itemized list the landlord sent, with the envelope
  • Your demand letter, final notice and certified mail receipts
  • Proof you gave a forwarding address
  • Texts or emails about the deposit
  • Copies of everything for the judge and the landlord

What to ask for

Ask for the amount wrongfully withheld, any statutory penalty your state allows, and court costs. The state pages show the penalty for each covered state, with a link to the statute you can show the judge.
