Please provide some additional information. Is this a mobile home, or is this a home that you had built to specifications?
(ordered) MD is an equitable distribution state, and if you didn't actually purchase the home until after you were married, he can ask for a share. Additionally, your income after the marriage is considered to be marital income, so if you have been paying for it while you were married, then it sounds like the house would be marital property and that he would be entitled to a share. You could probably keep the house, but you would have to buy him out.
THIS site had some great info.
