Ultimately, a co-tenant of jointly owned property can force a sale by bringing a partition action. A judicial sale is to be avoided if at all possible, because the court costs of a sale can quickly dissipate the equity in the property. The best solution is for you to buy out the ownership interest of your sister-in-law and her husband before he passes away. If that's impossible, the burden will be on them to sue you to partition the property. At the moment, you don't have to do anything.
