Legal Question in Family Law in California

First California is a community property state, that means that your income from work is 1/2 hers. Therefore you did not buy the house. Both you and the wife purchased the house with community property money. The exception would be if you had separate property funds to pay for the house, such as income from a trust fund set up by your parents, etc. The community property interests in the house is there regardless of how title in held. The court does not care that she is cheating on you. The only interest the court has in the property is whether it is community or separate and how it is divided. As for the children the court is interested their best interests. You need to consult with an attorney to protect your interests in the property and to provide the best home for the children.
