What is the name of your state? NJ, rebuilding new home, builder did visited the house couple of times, he knew what he was demolishing, after signing the contract the domilishion guy noticed Asbestos shingles, builder needs extra b'case that's not cover in contract (wrong contract does include demolishing the house) i paid for removing asbestos, thinking i will sue him after the whole house is completed because he can screw me more later on. Can i sue him later or it's too late ?
