Hi teedoubleu,
I'm a new member here, and I am not a lawyer. I'm a senior undergraduate looking to go to Law School so please take any information I give with a grain of salt. After doing some research I found some information for you.
Revised Article 3 of the Uniform Commercial Code provides the person with authority to sign checks for a corporation the ability to no longer declare his or her representative capacity on the check. Meaning that the person such as a controller or other representative no longer is personally liable over a NSF check. While this may be true, not all jurisdictions have adopted the Revised Article 3.
I do not claim this information to be accurate and urge you to wait for someone else with more knowledge to answer, or continue to do you own research.
Have a great day,
Jeff
