Security Deposit Not Returned in Boston: What Can I Do?
Massachusetts has strict rules about security deposits. Your landlord has 30 days after your tenancy ends to return it. If they break certain rules, a court can order 3 times the deposit plus your lawyer fees. For example, 3 times a $1,000 deposit is $3,000. You get this money only if you win your case and your landlord pays. This page lists your rights and what you can do. For help with your case, contact a legal aid office.
