You can tell I am not a lawyer, but in general contracts are worthless:

• If you work with someone honest you don't need a contract
• If you work with someone dishonest, they will use weasel words in the fine print that excuses them from responsibility down the line, so the contract is worthless

The bottom line is to work with honest people and go light on the paperwork.

When is the last time you made a deal with a handshake? How did it turn out?
