No, you cannot, while married, remove your spouse from a deed or vehicle title, even if you are making the payments on them. If you divorce, your marital assets will be divided between the two of you, and her marital infidelity will be one factor--though only one factor--in determining the economic arrangements of the divorce. Other factors in your favor will include use of the home (who is living there) and who is paying the costs of the home. So if you divorce, you may end up with the house, but that, or any other distribution of assets, would only happen in a divorce. It would be a good idea for you to discuss the situaiton in detail with a family law attorney, to undertand the likely outcome of a divorce, economially and in terms of child custody.
