A dad died 9 years ago, mom was executor and beneficiary. Mom never closed out the estate. She passed away 2 years ago and there are 4 siblings now in her will with brother as POA and executor that was badly mismanaged and there are extensive liens on the property. Dad's part of the estate was now taken over by the courts as was mom's apparently. The court appointed lawyer has not answered inquiries made by the 3 sisters, one of whom lives in the house and 2 that lives out of state.There has been no information for 5 months and What are the right for these sisters? The brother has signed notorized paper saying he is excluded from any inheritance. How does this proceed?
