My neighbor, who is an American, has been living with a Dominicana for the past eleven years. He is married to her sister because he was told that marriage would expedite his residency. Now he wants to terminate the relationship because of physical abuse by his novia. She wants a half from the sale of their house and half of all that they have together. She told him that her sister is also entitled to part of what ever he owns because he is her husband. The novia came into the relationship with nothing but worked hard to help him in his business. What do you think are his options? Thanks
