My friends, separated wife uses the excuse to see the kids and then ends up staying in the house. The kids don't know what to do but they allow her in the house when their dad is at work. He called the cops but said she is allowed to stay since they are not legally divorce. She was never on the tenant agreement and never paid rent. She has no where to go and no job but says shes there for her kids. How is that possible if two people are separated and she never financially or physically helps these kids but only when she can benefit from it? He works an early AM shift so she agreed to take the kids, he car is broke and keeps the kids from going to school. What advice can I give my friend from preventing her from continuing to live in his house? what steps would he need to do?
