Family Member Made Major Mistake - Advice Needed

[Joe Conklin]

I have a family member in New Jersey who took in a family which consist of husband, wife and a couple young kids.  No logic, strictly emotional decision because family member felt bad for them because they were being evicted and wanted to give the kids a place to stay.  Both parents are drug addicts who don't work and there is a restraining order on one of the parents because they are purposefully destroying the property.  Also DYFS has been involved due to harmful environment for kids.  Now family member wants them to leave and they won't.  There is an eviction court hearing later this week.

My question is, what is the most effective way to get them out of the property ASAP legal or otherwise?
