Quit claim deed with two owners. One is out of state.

[Joel Mayer]

I am trying to purchase a lot adjacent to the property that I currently own. The seller wants only $1000 and for me to take responsibility for the taxes and HOA fees that he hasn't paid. I think I want to do a quit claim deed to keep it easy but the owner and his son own the property jointly. I know his son now lives across the country. How can I do a quit claim if I cannot have both owners present?
