(B) In any county that maintains sectional indexes pursuant to section 317.20 of the Revised Code, each assignment, release, or cancellation of an interest in real property that is made by a separate instrument shall contain a description of the real property that is subject to the interest sufficient to enable the county recorder to index the assignment, release, or cancellation correctly, and the description shall include all of the following:

(C) If division (B) of this section requires a description of the subject real property to be contained in an assignment, release, or cancellation of an interest in real property that is made by a separate instrument, the omission in the assignment, release, or cancellation of any part of the description does not invalidate that instrument.
