Conn. Gen. Stat. § 47a-14e

The right of the owner of such property to collect such rent moneys from any tenant on or after the date of entry of a judgment as provided in section 47a-14d shall be void and unenforceable to the extent that the tenant has deposited such moneys with a receiver in accordance with the terms of the judgment rendered under said section, regardless of whether such right of the owner arises from a lease, deed, contract, agreement or understanding or otherwise. It shall be a valid defense in any action or proceeding against such tenant to recover possession of real property for nonpayment of rent or for use or occupation to prove that the rent alleged to be unpaid was deposited with a receiver in accordance with the terms of a judgment entered under section 47a-14d .
