ORS § 726.340
If a pawn ticket or memorandum is lost, destroyed or stolen, the pledgor shall notify the pawnbroker of the loss, destruction or theft in writing. The pawnbroker shall treat receipt of the notice as a stop against the pledge loan, and thereafter the provisions of ORS 726.310 and 726.320 do not apply to the pledge loan. Before delivering the pledge or issuing a new pawn ticket, the pawnbroker may require the pledgor to make an affidavit of the alleged loss, destruction or theft and may charge a fee of not more than $3 for the lost, destroyed or stolen ticket. Not more than five days after receiving notice of the loss, destruction or theft of the ticket, the pawnbroker shall permit the pledgor either to redeem the pledge or to receive a new ticket upon paying accrued interest. The pawnbroker shall incur no liability for permitting the pledgor to redeem the pledge or receive a new ticket unless the pawnbroker has previously received written notice of an adverse claim. This section does not limit or affect the pawnbroker's legal liability in cases where goods are stolen or other legal defects exist in the pledgor's title with respect to the pledge.
