Locks Law Firm only provides legal advice after having entered into an attorney client relationship, which our website specifically does not create. Conversations that originate from website messaging, chat or other two way web based engagement  do not create an attorney client relationship. It is imperative that any action taken be done on the advice of counsel. Because every case is different, the description of awards and cases previously handled do not guarantee a similar outcome in current or future cases. The firm practices law in Pennsylvania, New Jersey & New York as Locks Law Firm. Super Lawyers, Best Lawyers in America and other organizations that rate attorneys are not designations that have been approved by the State Supreme Courts or the American Bar Association.
