Sorry, I didn't mean to imply that you were making this my headache and certainly didn't mean to offend.  You're probably my favorite person here whose contact info I don't already have.  (I like to travel and have met at least a half-dozen folks from here in my travels.)

To clarify, this is the client's headache (of their own making), not yours!  It also likely creates a conflict of interest for you if you are considering representing both parties to a financial transaction.  The son's best interests and the father's could very well be at odds, both in this one transaction and in the activities of the joint property going forward.  No problem telling them that you're not comfortable representing them in this situation.
