Thank you for your question. I look forward to working with you to provide you the information you are seeking.
As an heir
and prospective administrator of the estate, you can file a motion in the probate court asking for approval of the estate sale based on preserving the estate. At this point this is all you can do, since you do not have the waiver back and this is an emergency issue to preserve the assets of the estate as much as you can. There is nothing more you can do without being administrator, as I am sure you already knew based on your question.
Legally this is one of those tough situations, but any heir or beneficiary of the estate can file a motion with the probate court to preserve assets of the estate for the heirs.
