Family is trying to keep grandma from visiting me. Any advice?

My mom and I have been living and caring for my grandparents for the past 18 years. Grandpa has recently passed away. And now 4 out of the 8 children have gone to court for guardianship and saying that we stole money. Well Mom had enough and decided to move out. And we want to have grandma spend the weekend with us, and now my aunts are trying to keep her saying she can’t spend the weekend.
