I have agreed to make something for a client. We have just been communicating by email and are now ready to sign a contract. The client has informed me he will be sending someone (who is not himself) to sign the contract. What clause should I include in the contract to make it clear that the person signing may not nescecarily be the one who the contract is with but are authorized on their behalf? The client is an individual, not a business, and this is an independent contractor relationship. I think what I’m looking for is Authority To Sign clause, but am not sure because they usually say that the person who is signing works for the client’s business. Since there’s no business involved I’m not sure if Authority To Sign is right. Could it say something like “those signing warrant they are authorized to sign by the those whose name appear in the contract”?
TL;DR example: Fred agrees to build Bob a house. Fred wants Bob to sign a contract and Bob sends his trusted agent Bill to sign on his behalf, even though Bob’s name is on the contract. Is there anything special the contract should have to make it valid in such a situation?
