Check out Williams v. North Carolina 325 U.S. 226 (1945) which indicates that a sister state can refuse to recognize divorce decree of another state and discussion of full faith and credit versus comity (first in time to file) and discussion of domicil versus residence.
NJ case law says domicil is different than residence which is that domicile indicates intent to establish bona fide residence for indefinite period or permanently with an intent to remain or return. (Gosschalk v. Gosschalk 48 NJ. Super 566 (App Div. 1955). The Court will look at indicia of domicil. This is where you need to establish a list of facts that supports NJ domicil (driver's license, voter's registration, insurance, bills, time spent, capital improvements on NJ residence to name a few).
Good luck.
