N.Y. Domestic Relations Law § 77-b: Duty to enforce

§ 77-b. Duty to enforce. 1. A court of this state shall recognize and

enforce a child custody determination of a court of another state if the

latter court exercised jurisdiction in substantial conformity with this

article or the determination was made under factual circumstances

meeting the jurisdictional standards of this article and the

determination has not been modified in accordance with this article;

provided, however, that recognition and enforcement of the determination

would not violate subdivision one-c of section two hundred forty of this

chapter or section one thousand eighty-five of the family court act.

2. A court of this state may utilize any remedy available under other

law of this state to enforce a child custody determination made by a

court of another state. The remedies provided in this title are

cumulative and do not affect the availability of other remedies to

enforce a child custody determination.
