Hi foxy,
basically the answer is no, you can't force your husband to put your house up for sale. The reason I say that is that on your divorce you will be entitled to half the value of your home, if your husband can afford to give you that money without selling your home then he is entitled to do so without the need to sell the home. If he cannot afford to give you your entitlement then he will have the option of either buying you out your half of the house by increasing his mortgage if he wants to remain there or as a last resort selling the house and you both split the proceeds
