There are three main options that are available in Connecticut to the tenant if this happens.
1. Negotiating with the landlord. You can speak to your landlord and try to dispute the charges or get them to compromise and refund some more of your deposit.
2. Negotiating with the landlord with a mediator. This is a more formal approach to negotiating with the landlord. The mediator can help with communication and may make it easier for you and your landlord to come to an agreement.
3. Take the landlord to a small claims court. Many states have a special claims court where you can sue your landlord for security deposit disputes without the help of an attorney or entity providing services that would be an extra cost. You can explore this option if the landlord refuses to come to an agreement with you through the earlier negotiations.
