My mother in law's elderly father is being cared for by her estranged sister. The sister will not allow her to visit her father, ignores phone calls regarding his health, and rarely allows her to speak with him on the phone. She has threatened to have the police stop the rest of the family from going into her home to see him, citing that the stress would cause him harm in his current condition. This is incredibly frightening for us and we have called social services to do a well-check, but by law they cannot report back to us on their findings. I am wondering if we, the family, have any legal recourse in seeing our father/grandfather/great-grandfather since the sister refuses to let us in. Any information would be greatly appreciated. Thank you!
