This may not be the appropriate place to ask this question but if not, maybe someone can point me in the right direction.
My former wife of over 25 years suffered a brain aneurysm and required two surgeries to correct the condition. During the second surgery she suffered a stroke in the area of the brain affecting memory and motor skills. After weeks of therapy she is about 80% functional (physically) but still has some memory loss especially in the recent several years. She is cognizant, can speak and carry on conversations, etc. She is being cared for by her new husband of 2 years. All is generally ok.
The support and answer I am seeking is this. Her spouse caregiver has denied access to all former friends and family, including her children and grandchildren. Phone calls are rare and tightly monitored. The stoke victim herself is moderately wealthy with two properties. There is concern among family members that her new spouse does not have her (or family) best interests in mind. What recourse, if any, does a family (son/daughter) have if their mother is being denied access to them and her wealth and properties may be at risk. Note that there is no evidence of any physical abuse or neglect.
