How to get your deposit back in Massachusetts

1. Send a written demand. Put the deadline your landlord missed and the statute (Mass. Gen. Laws ch. 186, § 15B) in writing, by certified mail with return receipt, so you have proof of the date they received it.
2. Keep your records. Move-out photos, the walkthrough checklist, your lease, and proof you gave a forwarding address are your evidence if the landlord disputes the claim.
3. If they don’t pay, file in small claims. You can ask a Massachusetts small claims court to order the deposit returned, and — under Mass. Gen. Laws ch. 186, § 15B — to seek up to three times the deposit if the landlord failed to meet the statute's requirements, plus interest and costs plus attorney's fees, which the court may award if you prove your case. The small-claims dollar limit varies by court within the state, so check your county’s limit before filing.
