Dating a contract
Under Michigan law, you are generally bound by a contract that you sign even if you have no knowledge of its contents.
Unless you can prove that the other party engaged in fraud or other wrongdoing in preparing the contract or inducing you to sign it, you will be required to abide by it.
The parties do not necessarily have to sign the same copy of the contract in order for it to be binding.
In other words, you can provide that your contract is entered into "as of" or "effective" a date earlier than the date of the contract is actually signed.However, if it is not possible to have have a contract revised and reprinted before it is signed, make sure that any changes made to the contract by hand are initialed by each party to the contract.
