Pennsylvania has adopted a version of the Revised Uniform Law on Notarial Acts. The new law, which takes effect on October 26, 2017, codifies provisions relating to notaries in Title 57 and repeals existing laws relating to notaries.
The new law will be of interest not only to notaries but to lawyers and anyone who employs notaries.
A copy of the law (57 Pa.C.S. §301-331) is available here. An overview of its major changes to prior law is available here. The National Notary Association has a useful compendium of various PA statutes that are related to the notary process: https://tinyurl.com/y6vuvlfp
