N.Y. Real Property Actions & Proceedings Law § 301: Conveyance and record as evidence

§ 301. Conveyance and record as evidence. 1. The certificate of the

acknowledgment or of the proof of a conveyance, or the record, or the

transcript of the record, of such a conveyance, is not conclusive, and

it may be rebutted, and the effect thereof may be contested, by a party

affected thereby.

2. If it appears that the acknowledgment or proof was taken upon the

oath of an interested or incompetent witness, the conveyance, or the

record or transcript of the record thereof, shall not be received in

evidence until its execution is established by other competent proof,

except in a case where the title to the land conveyed or affected by

such conveyance or instrument has passed to a subsequent purchaser for a

valuable consideration.
