my brother passed away and my mother wants to file grandparent visitation forms. can we get the forms and bring them home?

She can try to file Grandparent visitation rights, but its very difficult to get in New Jersey.  you have to prove you have had a prior long term relationship with the child and thta its in the child's best interest. The parents have the right to raise their children the way they want, and that includes contact with either set of grandparents or no contact at all.  Good luck !
