The series was created by Rob LaZebnik and produced by Witt/Thomas Productions in association with Warner Bros. Television.
Due to low ratings, the series was pulled from ABC's schedule after four episodes had aired.
Greg Giraldo was, in reality, a graduate of Harvard Law School, nearly top of his class, and became a lawyer for a while before becoming a comedian.
After a year as an attorney, Giraldo fell out of love with the profession and launched his comedy career, only referring to his law background very occasionally on the stand-up circuit until he starred in this series.
Supporters of Common Law pointed to the Saturday 9:30/8:30 time slot as a factor in its poor ratings and subsequent cancellation despite having the long-running ABC sitcom Coach as its lead-in.
