Liability on contractor code

Hello,
Our organization has contracted to develop a website for a local organization. Thru the process, the contractee has been designated the “owner” of the code. Now the project is growing to where other organizations in the US want to use the product, and a few want the code to be able to make modifications. As the contractor, who has met all requirements of the project, is there liability that could be passed to us if a recipient of the code deems it crap (for lack of a better word)? What steps are necessary for us to protect ourselves if there is such a liability?
