Forwarding address matters to the clock
Connecticut does not use a simple 21-day rule in every case. The statute uses the later of 21 days after termination or 15 days after the landlord receives the tenant’s written forwarding address.
Forwarding-address timing matters. Connecticut’s ordinary 21-day rule must be read together with the written forwarding-address provision. Educational information only.
