Painter sues dealer

Painter Dean Levin has sued Upper East Side dealer Robert Blumenthal for nearly $200,000, claiming non-payment after a sold-out show in May 2014. The suit pits a 26-year-old artist represented by New York dealer Marianne Boesky and collected by Leonardo Di Caprio against a real estate investor and dealer whose gallery has been open for just a year.

Details here. 

The question is: "Did Levin have a contract stipulating when Blumenthal was supposed to pay him?" Is it 30 days after the sale of the work? or is it 30 days (or whatever) after Blumenthal gets paid?"

The moral of the story: Have a contract!
