But the lives of a family in Indiana who've contracted to buy property, taken out a loan, hired movers, whatever, don't stop because a woman they don't know is missing in Colorado. Assuming a contract for sale had been signed by both SM and BM (and that's certainly what it sounds like), the sellers are contractually bound to transfer title to the property. They also owe a real estate commission to one or more realtors. I suspect BM has no choice in this matter. The buyers likely could sue for specific performance if he didn't arrange to sign for SM, in her absence.
