That depends on two things:
1) how much they owe you
2) do you feel like pulling in all that time and effort.

For me if they own my $500 or less I would go to a collection agency.
if its more then $500 then I would go to court. But my contract has me covered, The family pays my costs.

You and your family are the only ones who can truly decides if going to court is worth it.
