NJ follows the same rules: once the filing for D has been made, each person is responsible for their own debts accrued after filing process kicks off, and the "Discovery Phase" (the first round of documents due to the court/lawyers after the D filing) backs that up by only requiring financial positions as of the D filing date. My xH bought a brand new car, took a $34,000 loan three weeks after leaving, and the court awarded him with sole responsibility for payment of the full loan amount. Oops, too bad!
