Interest Rate Information | Tenant/Landlord Education

The Department of Banking investigates rental security deposit complaints, issues cease and desist orders and refers matters to the Attorney General's Office for legal action.  If you have a complaint regarding a rental security deposit issue, please download and complete our customer assistance form below.  All complaints will be handled in the order in which they are received.  In most instances, responses will be issued to consumer complaints within 60 days.

Going to Court (Small Claims) to Resolve Disputes

As a simple, quick alternative, landlords or tenants with disputes about rental security deposits may bring small claims suits in a Housing Session, or in the local Geographical Area Court if there is no Housing Session, provided that the dollar amount claimed falls within the jurisdiction of the small claims court.

Refer to your local telephone book blue pages under State of Connecticut Judicial Department for local court addresses or visit the Judicial Department website.
