Give your landlord your forwarding address in writing. In Connecticut it affects the deadline or the penalty.

What to do to get your deposit back

Photograph every room when you move out (walls, floors, appliances, inside cabinets). Keep your move-in photos too.
Send your forwarding address in writing, with the date.
Mark the deadline: 21 days after you move out.
If it's late or the deductions look wrong, send a written demand letter that cites Conn. Gen. Stat. 47a-21.
Still nothing? Small claims court is built for this, and you usually don't need a lawyer.
