Conn. Gen. Stat. § 42-422: Reporting early termination to consumer reporting agency.

If a consumer lease is terminated before its scheduled expiration by mutual agreement of the holder and lessee, the holder may not report the early termination to a consumer reporting agency as a default by the lessee or guarantor. This section does not preclude the holder from reporting to a consumer reporting agency a previous default by the lessee or guarantor under the lease or a later default under the early termination agreement.
