I don't know the legal side of things, however, last year I encountered this issue! We were four days from closing and the seller died. He had a will and had assigned his daughter as executer. So, the forms were all changed to read:"Janey Doe, Personal Representative of the Estate of John Doe." The family actually continued with the sale, as planned, but had to hustle to get all of the paperwork filed with the Register of Wills prior to the sale.
FYI: We were warned by our agent that we would have lost our goodfaith deposit if we decided to back out of the sale. The seller had already complied with all of our repair requests.
Hope this story helps!
