New Jersey § 2a:34-70

§ 2a:34-70.

a. Except as otherwise provided in section 16 of this act, 1 a court of this State may not exercise its jurisdiction under this article if at

the time of the commencement of the proceeding a proceeding concerning the custody

of the child had been commenced in a court of another state having jurisdiction substantially

in conformity with this act, unless the proceeding has been terminated or is stayed

by the court of the other state because a court of this State is a more convenient

forum under section 19 of this act. 2 b. Except as otherwise provided in section 16 of this act, a court of this State,

before hearing a child custody proceeding, shall examine the court documents and other

information supplied by the parties pursuant to section 21 of this act. 3 If the court determines that a child custody proceeding was previously commenced

in a court in another state having jurisdiction substantially in accordance with this

act, the court of this State shall stay its proceeding and communicate with the court

of the other state. If the court of the state having jurisdiction substantially in accordance with this

act does not determine that the court of this State is a more appropriate forum, the

court of this State shall dismiss the proceeding. c. In a proceeding to modify a child custody determination, a court of this State

shall determine whether a proceeding to enforce the determination has been commenced

in another state. If a proceeding to enforce a child custody determination has been commenced in another

state, the court may: (1) stay the proceeding for modification pending the entry of an order of a court

of the other state enforcing, staying, denying or dismissing the proceeding for enforcement; (2) enjoin the parties from continuing with the proceeding for enforcement; or (3) proceed with the modification under conditions it considers appropriate. 1
