With the exception of "big time" performers, most folks play on the basis of a "gentleman's agreement and a handshake", otherwise known as an oral contract. My experience has been that such arrangements are usually satisfactory, but sometimes, one or the other party renegs. Success probabilities for litigation are variable and dependent on many factors. I would greatly appreciate hearing from any 'Catters who have had to wrestle with this problem before, from either side of the equation, and am especially interested in any creative solutions you might have come up with. No point reinventing the wheel unnecessarily.
