There seems to be little doubt that the acceptance of rent after a forfeiture waives that forfeiture and creates or accepts a new tenancy. Hartford WheelClub v. Travelers Ins. Co., 78 Conn. 355, 359; Camp
v. Scott, 47 Conn. 366, 370; Hudson v. Kuszynski,12 Conn. Sup. 264, 266. It is totally inconsistent for a landlord to accept a rent check, whether absolute or conditional payment, under a nonexisting tenancy. The court is required to decide whether or not the plaintiff did accept the rental checks in issue as payment. "A long, unexplained retention of a check tends to show its acceptance for the purpose for which it was given." Borst v. Ruff, 137 Conn. 359,362.
