210 Pa. Code Rule 1112
(c) Petition for Allowance of Appeal.
(f) Entry of appearance. Upon the filing of the petition for allowance of appeal the Prothonotary of the Supreme Court shall note on the record as counsel for the petitioner the name of his or her counsel, if any, set forth in or endorsed upon the petition for allowance of appeal, and, as counsel for other parties, counsel, if any, named in the proof of service. Unless that party is entitled by law to be represented by counsel on allowance of appeal, the Prothonotary shall upon praecipe of any such counsel for other parties, filed at any time within 30 days after filing of the petition, strike off or correct the record of appearance. If entry of appearance in the trial court extends through appeals, counsel’s appearance for a party may not be withdrawn without leave of court. Appearance cannot be withdrawn without leave of court for counsel who have not filed a praecipe to correct appearance within the first 30 days after the petition is docketed, unless another lawyer has entered or simultaneously enters an appearance for the party.
Comment:
Based on 42 Pa.C.S. § 724(a) (allowance of appeals from Superior and Commonwealth Courts). The notation on the docket by the Prothonotary of the Superior Court or Commonwealth Court of the filing of a petition for allowance of appeal renders universal the rule that the appeal status of any order may be discovered by examining the docket of the court in which it was entered.
The United States Postal Service form may be in substantially the following form:

The transmittal should be taken unsealed to the Post Office, the Form 3817 Certificate of Mailing, Form 3800 Receipt for Certified Mail, Form 3806 Receipt for Registered Mail, or other similar United States Postal Service form from which the date of deposit can be verified should be obtained, cancelled, and attached to the petition, and the envelope should only then be sealed. Alternatively, the cancelled Form 3817, Form 3800, Form 3806, or other similar United States Postal Service form from which the date of deposit can be verified can be submitted to the Prothonotary under separate cover with clear identification of the filing to which it relates.
It is recommended that the petitioner obtain a duplicate copy of the Form 3817, Form 3800, Form 3806, or other similar United States Postal Service form from which the date of deposit can be verified as evidence of mailing. Since the Post Office is technically the filing office for the purpose of this rule, a petition which was mailed in accordance with this rule and which is subsequently lost in the mail will nevertheless toll the time for petitioning for allowance of appeal. However, counsel will be expected to follow up on a mail filing by telephone inquiry to the appellate prothonotary where written notice of the docket number assignment is not received in due course.
The Rules of Criminal Procedure require counsel appointed by the trial court to continue representation through direct appeal. Pa.R.Crim.P. 120(A)(4) and Pa.R.Crim.P. 122(B)(2). Similarly, the Rules of Criminal Procedure require counsel appointed in post-conviction proceedings to continue representation throughout the proceedings, including any appeal from the disposition of the petition for post-conviction collateral relief. Pa.R.Crim.P. 904(F)(2) and Pa.R.Crim.P. 904(H)(2)(b). The same is true when counsel enters an appearance on behalf of a juvenile in a delinquency matter or on behalf of a child or other party in a dependency matter. Pa.R.J.C.P. 150(B), 151, Pa.R.J.C.P. 1150(B), 1151(B), (E). It would be rare for counsel in such cases to consider withdrawing by praecipe, but the 2020 amendment to the rule avoids any possibility of confusion by clarifying that withdrawal by praecipe is available only in matters that do not otherwise require court permission to withdraw.
With respect to appearances by new counsel following the initial docketing of appearances pursuant to paragraph (f) of this rule, please note the requirements of Pa.R.A.P. 120.
Where an appellant desires to challenge the discretionary aspects of a sentence of a trial court, the ‘‘petition for allowance of appeal’’ referred to in 42 Pa.C.S. § 9781(b) is deferred until the briefing stage, and the appeal is commenced by filing a notice of appeal pursuant to Chapter 9 rather than a petition for allowance of appeal pursuant to Chapter 11. See note to Pa.R.A.P. 902; note to Pa.R.A.P. 1115; Pa.R.A.P. 2116(b) and the note thereto; Pa.R.A.P. 2119(f) and the note thereto.
