I can only speak in general terms; each state may have its own laws and terms.
If a property is owned by two or more people, the only way one can sell is with the agreement of all other interested parties. Having said that, I also say that if one or more of the parties want to sell, that owner can force the sale through the courts. ( I have forgotten the term for this, possibly "partition sale.") When this is done, the property is usually auctioned off. This does not mean that one or more of the other owners cannot bid on it. Naturally, an owner(s) would have an advantage over any non-owners at such an auction, since they wouldn't have to come up with as much money. (A bank will take in account ppartial ownership when financing such a loan. They love those, since their outlay, or risk, is less for the same secured property.)
The mortgage is secured to the property, but not to anyone whose name is not on the document. (Example: If both parties walk away from the property, the bank holding the mortgage forecloses, sells the home (usually for less than its value), and any balance leftover after the sale is still owed by the person whose name is on teh mortgage. The other person, even an owner, not having signed a mortgage, cannot be held accountable for that balance.
What Shel said is correct. Lawyers always want signatures from everyone involved to protect their client from possible litigation. Having those signatures does not stop a law suit, but it does make it hard to claim lack of knowledge about a sale.
And, yes, it is nice to se you again, NC. Of course, it's always nice to see Shel.
