Executor does not want to sign
Zac and Bern's sister died, her name is Mary. Mary leaves the house to Bern as heir to the house as stated in her will. Bern wants to sell the house. Zac is the executor of the will and he doesn't want to sign (he hides and does not to talk to anyone to do his job as executor). The house is foreclosure in two weeks.
Bern want to sell the house, what are his options?
Bern probably needs to get a lawyer
Generally speaking, Bern should hire an attorney to file an emergency motion in the probate case to remove and replace Zac as Executor. Foreclosing lender / attorney / trustee should be advised of the death of the mortgagor and litigation regarding the Executor.
While those things are happening, Bern should be finding a buyer who can close quickly.
