(a) Relinquishment of possession occurs when the landlord receives a statement signed by each adult tenant of a rented or leased premises stating that the tenant has relinquished possession of the rented or leased premises and has no intent to return.
(b) Abandonment of possession means all tenants have physically vacated the premises without the intent to return. There shall be a rebuttable presumption that the tenants have abandoned the premises if:
(1) The landlord provided all tenants with a written property abandonment notice, by leaving the notice at the rented or leased premises and by sending the notice by certified mail to the last known address of at least one adult tenant. The property abandonment notice shall also comply with subparagraph (d); and
(2) At least 2 of the following conditions were present:
(A) All adult tenants of the rented or leased premises have notified the landlord in writing of their intent to vacate the premises by a certain date and that date has passed, provided that the written notice of one adult tenant who has lawful possession to the premises pursuant to an order under RSA 173-B shall suffice.
(B) All keys to the rented or leased premises have been returned to the landlord, which shall include leaving all keys in the rented or leased premises.
(C) The tenant or tenants have removed from the rented or leased premises all or the majority of their personal property, and the only items remaining in the premises are inconsistent with the continued use of the premises.
