At some point, the PR can only do what everyone will cooperate with. If they refuse all communication, refuse to let the house sell and refuse to pay any bills, the PR cannot continue propping up the estate with no hope of a settlement. Yes, its a waste, but the burden is not the PR's alone. At some point, the heirs have to cooperate or the house will never sell.
Good point, it would be helpful for the heirs to agree. It is certain that none of the estate's beneficiaries would want to lessen the amount that they can recieve by the estate being wasted. You should contact a probate attorney for advice on how to deal with the PR.Please note that THESE COMMENTS ARE NOT INTENDED AS LEGAL ADVICE and are for informational purposes only.
