13 Pa.C.S. § 8406: Obligation to notify issuer of lost, destroyed or wrongfully taken security certificate.

If a security certificate has been lost, apparently destroyed or wrongfully taken and the owner fails to notify the issuer of that fact within a reasonable time after the owner has notice of it and the issuer registers a transfer of the security before receiving notification, the owner may not assert against the issuer a claim for registering the transfer under section 8404 (relating to wrongful registration) or a claim to a new security certificate under section 8405 (relating to replacement of lost, destroyed or wrongfully taken security certificate).
