To apply for gpoa from court only know the year it was made

This discussion is about obtaining a copy of a Power of Attorney (POA) document that was registered and sealed by the court between 1981-1982. The original applicant only remembers the approximate year of registration and needs the document for their children's future. They are seeking guidance on how to apply for a copy, especially as the executants (grandparents) may no longer be alive. The validity of the POA if executants are deceased is also a consideration.
