My husband and I have currently been seperated for 6 months. We have 2 children and want to stay in our house. Can he force me to sell?

your husband can't force you out of a house, or force a sale of a house, unless and until he gets a court order saying you have to do these things.  getting that order takes a lot of work, and usually means a divorce been filed.   most divorce cases end in a negotatied settlement, without the court issuing orders to force a sale or force someone to leave.  if you and your husband are going to stay separated, eventually you WILL have to decide what to do with the house.  but unless he gets a court to agree with him, he can't FORCE you to do anything.  good luck!
