How to sign a contract for a Limited Liability Company in Alabama:

When entering into an agreement for the LLC (your company) you should sign as follows:

(signature) John Doe, President of
Widget Enterprises, LLC

Signing as shown above is intended to limit your personal liability in contracts to the LLC.  This only works though, if you make sure the contract states in the initial recital that this agreement is between: Other Person/Company  and Your Company, LLC, but NOT YOU PERSONALLY.   Once again, make sure the agreement does NOT add your personal name in the contract or the initial recital of the contract.
