Who signs the contracts?
Depending on your responsibilities for any given event, contracts will be signed by whichever party has agreed to sign them–if that makes sense. Basically, if you have signed a contract with your client that gives you the authority to contract with all vendors, then YOU will sign. If you have agreed to participate in only negotiations for contracts, but choose to avoid the liability, then your client may be responsible for signing. Remember, signing a contract does make you liable for damages in the event something goes wrong, so be very cautious when you agree to sign.
