Just a quick correction for your reference - it's not a marshall, it's a sheriff.
As to your situation, you can petition the Court for a hardship stay Monday morning. You MUST do it Monday morning, first thing. The court opens at 8:30 AM. Be there at 8:30 AM to file the application for the stay. Advise the sheriff who comes to do the lockout that morning that you've applied for the stay and request he not perform the lockout pending the court's decision. One of you should remain in the home at all times to protect your tenancy. The other should go file with the court. Whichever one of you stays at home should be respectful to the sheriff's officer who's just there to do his or her job.
I cannot stress this enough: you MUST file the stay before the sheriff arrives. You cannot ask the sheriff to wait around while you file the motion to stay. Go to the Hudson County courthouse, ask for the special civil part. Tell the clerk there you need to file an application for a stay of execution on the warrant of removal. Tell him or her it is an emergency application.
