I posted this in the Oklahoma Forum but thought I would try here, also. This question was asked in that forum on 06/25/2010: Does Oklahoma state law require us to send a copy of a paid note to the customer?
A response was never given. In lieu of the original note papers (stamped "paid" with the date of payoff), our bank would like to begin sending a one page notification that the note has been paid -- less private information being mailed, more cost effective, etc. Of course, if a lien release is involved it would be included. Also, let the customer know we will retain the original for a certain time in the event it is wanted. Four years later, can any Okie banker or someone familiar with Oklahoma rules and regulations assist?

Different forum, but this prior post may help.
