New York Consolidated Laws, Surrogate's Court Procedure Act - SCP § 204. Presumption of jurisdiction

Where the jurisdiction of the court to make a decree or other determination is drawn in question collaterally, the jurisdiction is presumptively and in the absence of fraud or collusion, conclusively established by an allegation of the jurisdictional facts contained in a verified pleading. Jurisdiction of the parties is presumptively proved by a recital to that effect in the decree.
