Legal Question in Legal Ethics in Pennsylvania

It depends on who you are asking. If you are asking the opposing party in your lawsuit, then no. The request must be written in a certain format with certain warnings. If you are requesting inspection of records as a part of the Right To Know Act, then yes, a written request is enough. If you are requesting inspection of records or books as a shareholder, partner, or member of a business, then a written request with proof of delivery to the business' secretary is sufficient. Good luck.
