Does Divorcee Have Rights to Property, Even if Her Name is Not on Title?

“My sister lives in Cary, IL. Her husband moved out 3 years ago after receiving a large amount of money from his fathers estate and paying cash for a new house. He and my sister are on the title to the house my sister still lives in with their two kids but she is not on the title to his new home. ┬áHe just ran out of money and is going to sell the house, what does she have rights to at this point?

In this particular case, your sister will have to look to what the court ordered was to be done with the house following the divorce, as the court almost certainly would have addressed this in their divorce order.
