Can a gag order be placed on a sibling who is discussing my mother's property on social media? Back story:
Mom went to assisted living, sibling starts claiming mom's expensive items. I tell them no, attorney tells them no. Sibling rants all over facebook and I start getting texts, calls and screenshots. The home is unoccupied and full of stuff. It's a sitting duck now! There is no court case just indecision on how to move forward with mom's property. I was told to request a gag order but I don't know if this situation applies.
Alert the local police and ask if they can do periodic drive-bys. Some may have the time; others may not.
I don't know whether you yourself have access to the house, given the situation with the sibling, but if you do:
Find a good security service and get a system installed as quickly as you can. Also, alert the neighbors to be on the look out. This won't help when they're asleep at night though.
Get those little window alarms and put them on the inside of the windows. Put chairs and other furniture in pathways to block anyone's easy ability to walk through the house.
There are probably other good methods, but the issue turns basically on the irresponsible actions of the sibling. You may end up needing to request something more powerful than a cease and desist, something like a restraining order, although I don't know whether or not a court would be sympathetic, especially given the apparently discord in the family.
You can also block windows and doors with furniture.
All of this is moot thought if your sibling is denying access to the house. In that case, you'll have to rely on legal action, which you should discuss with your attorney. I would consider a PPO first though, if your attorney thinks you can get one that prevents the sibling from sharing data. I don't see why a "gag order" doesn't apply though.
