What is the legal right, according to Sharia, of a divorced woman and her nine children to the property of her husband, who divorced her 20 years ago and did not provide for them, knowing that she contributed to the construction of the house where his current wife resides?

It was previously stated that assisting the husband in building a house and whether she establishes a right to it is a matter of dispute that requires evidence, and it is best for the Sharia court or Islamic centers to look into it. The maintenance of young children is obligatory upon their capable father; otherwise, he is sinful. If the wife or anyone else spends on the children with the intention of claiming it back from the husband, that is permissible.
