A hearing before the Register (other than a
caveat hearing) is generally initiated by the filing of a Petition
for a Citation to Show Cause why a respondent should not perform
some act or acknowledge some fact regarding the grant of Letters.
The Register will issue the original citation
to the petitioner, who must make service of a photocopy of the citation
and the petition upon all interested parties at least 10 days prior
to the return date shown on the citation. Personal service and service
by certified mail, return receipt requested are both accepted by
The respondents and other parties in interest
may but are not required to file an answer or preliminary objections
on or before the return date. The failure to file a responsive pleading
will not be conclusive of any matter at issue.
