how quick can I sell the home that my stbxw and I own if the divorce is:

a) uncontested b) contested

Can my stbxw drag it out for years until our home can be sold? For example: If a buyer comes around with a good offer can that sale be prevented if my wife keeps on saying no to the offer? Since I'm the breadwinner I can just stop paying the mortgage to force her hand. I know it's stupid but she needs the money more than I do. Worst case: I stop all payments (mortgage, utils etc)
