father in law passed away

My father in law passed away dose his wife own all the land? the land was in both of there names all but one lot that was in his name only dose she own that also?

From what I could tell, it goes to the remaining spouse. There would have to be a new will,or something, made up.
You need to ask your husband to talk to his mom about it. The will needs to be changed also. My dad passed away in 96 and my mom had to get everything changed. May take a while but it needs to be done as soon as possible. You mother-in-law can also talk to her attorney.

There was no will,and the one lot that was in my father in law name only is the lot we bought and its payed, for but cant get the deed because they say its not hers to sell because it was in his name only,they say she gets 1/3 and all the kids get 1/10 of the lot that was only in his name WHAT TO DO?

Talk to an attorney is the best advice that I,or anyone, can give you.
