Some contracts, such as for a paper delivery job, are usually signed by parents, who will, usually, be obligated to make it good if you fail.
This is a very open ended question without a great deal more information about the purpose of the contract.
I am hoping by now you have this sorted, but just in case: The best person to ask about the requirements for signing the contract would be the other party or parties signing the contract.
If they don't know, then they may be able to reference the same attorney that drew up the contract for accurate advice.

So you can't do it on your own unless you got a parent to do it for you. [ PunkieFreak4690's advice column | Ask PunkieFreak4690 A Question ]
