Legal Question in Construction Law in California

1. You haven't asked a question. 2. You provide no information about why the contractor thinks they are entitled to more money.

There are many situations in which a contractor is entitled to a contract modification increasing the contract price. There are many other situations in which a contractor may need or want more money for the job and not be entitled to it. All depends on the facts and circumstances of the job and the terms of the contract. So with no information and no question, I can't help you.
