210 Pa. Code § 65.44
The names of the parties in a caption for an appeal from a divorce, equitable distribution, custody, visitation or child support decision shall include the full names of the parties if listed as such in the caption of the trial court's docket. The Court, however, in a custody action upon application of a party and for cause shown, in its discretion may order that the names of the parties listed in the caption be initialized if the Court determines that a child may be identified from the full names of the parties in the caption, pursuant to Pa.R.A.P. 904(b)(2). This rule applies only to the names in the caption and does not apply to the text of a circulation or order of the Court. In such documents, the name of the child shall be initialized or the document shall refer to the child as "Child."
