Can my landlord keep my security deposit after I moved out?

Under Texas Property Code §92.103, a landlord must return your security deposit within 30 days of you vacating — provided you gave a forwarding address in writing. If he fails to do so without a written itemization of deductions, he forfeits the right to keep any portion. You can sue in small claims court (Justice of the Peace Court) for up to three times the deposit amount plus $100 and attorney's fees under §92.109. Send a certified-mail demand letter first, then file if he doesn't respond within 10 days.
