Divorce in New York is heard only by the Supreme Court, and the County Clerk of the county where the action was brought keeps the matrimonial file. Domestic Relations Law 235(1) closes it: the clerk may not permit a copy, examination or perusal of the pleadings, affidavits, findings of fact, conclusions of law, judgment of dissolution, written agreement of separation or testimony by anyone other than a party or the party's attorney, except by order of the court. Section 235(5) lifts the confidentiality 100 years after filing. The Statement of Net Worth required by DRL 236(B)(4), the settlement agreement and the judgment are all inside that closed file.
A non-party can obtain a certificate of disposition from the County Clerk under section 235(3), confirming that a judgment was entered, and nothing more without a court order. The court system's eCourts applications index Supreme Court cases, and the general sealing rule for other civil records, 22 NYCRR 216.1, requires a written finding of good cause.
