The word is QUIT, not QUICK.  But Mr Smith was probably a do-it-yourselfer who didn't know that either, and it doesn't matter.  

I did a search and found something that says "An intrafamily transfer & dissolution is a deed that transfers ownership from one family member to another. Dissolution occurs usually in the case of a divorce, where ownership is transferred from the couple to just one person."

So were your client and Mr Smith related?  Were they ever married?  Not that it matters.  We're just curious here.  

Ignore this chatter about estate taxes and gift taxes, those are just for rich people.  Had the property been sold during Smith's lifetime, intent would matter.  It was JTWROS, he died, the basis is FMV at date of death. 

Are you sure Smith was Mr?  Was there an autopsy?  Not that it matters.  We're just curious here.
