Among their powers notaries public administer oaths and receive and certify acknowledgments or proof of deeds and other instruments in writing (Executive Law §135). An acknowledgement provides proof of the identity of the purported signatory of a document. It reads (Real Property Law §309-a):
On the ____ day of ____ in the year ____ before me, the undersigned, personally appeared ____, personally known to me or proved to me on the basis of satisfactory evidence to be the individual(s) whose name(s) is (are) subscribed to the within instrument and acknowledged to me that he/she/they executed the same in his/her/their capacity(ies), and that by his/her/their signature(s) on the instrument, the individual(s), or the person upon behalf of which the individual(s) acted, executed the instrument.
Domestic Relations Law §236(B)(3) provides that an agreement made before or during the marriage, shall be valid and enforceable in a matrimonial action if such agreement is in writing, subscribed by the parties, and acknowledged . . . .”
Parties often will resolve their divorce actions through with Separation Agreements or Stipulations of Settlements, the terms of which are incorporated in their Judgment of Divorce. Those agreements and stipulations often survive the entry of the Judgment of Divorce as independently enforceable contracts.
In his June 10, 2015 decision in Defilippi v. Defillipi, Westchester County Supreme Court Justice Paul I. Marx, held that agreements that are entered within pending divorce actions and conclude those actions need not be acknowledged. They must only meet the requirements of C.P.L.R. 2104 and, if not entered in open court, be written, signed and filed with the county clerk.
