Sorry for your loss of your mother, This forum is about appraisal of real property and we are not lawyers, Here is what you should do and it is complicated.:
You’re dealing with a situation that falls under estate and probate law, so the first step is to speak with a qualified attorney. Before you can buy your late mother’s condo, the estate has to be properly opened, an executor or administrator must be legally appointed, and the property must be transferred or sold according to state probate rules. A lawyer can make sure the title is handled correctly, all heirs’ rights are protected, and the sale is done in a way that’s legally valid and avoids future problems.
I wish you well and again sorry for your loss
