My father in law has passed away, but my mother in law is still alive. My father in law has passed on the property to my husband. My question is, is this possible while the mother in law is still alive?
If the property is acquired by your Father in Law from his own self earned income, then he is free to transfer the same to your husband and there is no bar for him to do such thing and the factum of the mother in law being alive would make no difference.
