My son is splitting up with unmarried mother of his children, ages 3 and 1.5, they have a home together, only moraged for one year, they are still in the home trying to share caring for the children, he is there nights and four day a week she 3 days and no nights-he pays for moorage, she moorage. We put all the money in to the house- i.e. down and 401K money- she put nothing into it. What can we do- where do we start and how do we protect moorage?--Can we ask her to leave -it seems she is trying to get the house. My son is thinking of getting an apt. but his name is on the morage and I am concerned that, that would be a disadvantage to him in resolving this with the least amount of damage.
