My grandfather and grandmother have been married for 45 years and had no children together. This means we have grandfathers side of the family and grandmothers side of the family (from previous marriages). I'm on the grandmother's side of the family.
My grandfathers side of the family has taken him and won't let us speak to him. They say they have power of attorney (as if that gives them legal right to forcibly remove him from the house). We spoke to my grandfather the day before he left and he adamantly said that he did not want to leave. His side of the family told us that they were just taking him for a few days but now won't let us nor his wife have any contact with him nor do we know where they took him.
Is this legal? What should we do?
Can I now ask, what would be stopping you from taking action right now, not waiting...?
The court, usually in a criminal case, issues the writ.
Prior to the current situation, they were living together?
If APS does not help, see an attorney who will issue a writ of habeas corpus-which means to produce the body (yes, also a live body). Those holding the family member must produce the body before the court who will determine GF's welfare and any requirements for custody. imo. Family law, elder law...get help...
There is always more to the story, called the back story.
Don't get mired in details, or stopped in your tracks by "he said, she said" family issues. Your grandparents are vulnerable and married, each should have the right to know the welfare of the other. At their age, don't wait to find out or help your grandmother make contact.
There are also very urgent financial issues, don't you think?
Have your grandmother make the police report.
This happens and all the other family members are left wondering, "What happened"?
The families get divided.
Each spouse is vulnerable to elder abuse when spirited away by the step-families.
