23 Pa.C.S. § 5614 – Revocation

(a) Prepetition.— Prior to a petition being filed under section 5612 (relating to petition for approval of a designation), the designator may revoke a standby guardianship by simple destruction of the designation and notification of the revocation to the standby guardian.
(b) Postpetition.— After a petition has been filed, the designator may revoke a standby guardianship by:
1. (1) executing a written revocation;
2. (2) filing the revocation with the court; and
3. (3) notifying the persons named in the designation of the revocation in writing.
(c) Unwritten revocation.— Regardless of whether a petition has been filed, an unwritten revocation may be considered by the court if it can be proven by clear and convincing evidence.
