To use a contract for a contractor or not to use a contract?

[Bennett Schwartz]

Hi BP,

I'm in contract on my first flip !!!! 

I'm working on a smaller size flip of a triplex and my attorney says I should write up a contract for my contractor. Some people that I know who do similar jobs don't because the amount of money they would spend on lawyer fees would cost more than the lost. 

Anyone have any advice?

Thanks,

Bennett
