77 Pa. Stat. § 931
Whenever, after an injury, any employe or his dependents shall have entered into a compensation agreement with an employer, who has not accepted or complied with the provisions of section three hundred five, or shall file a claim petition against such employer, he may file a certified copy thereof with the prothonotary of the court of common pleas of any county. The prothonotary shall enter the amount stipulated in any such agreement or claimed in any such claim petition as judgment against the employer, and where the amount so stipulated or claimed is for total and permanent disability, such judgment shall be in the sum of thirty thousand dollars. If the agreement be approved by the department, or compensation awarded as claimed in the petition, the amount of compensation stipulated in the agreement or claimed in the petition shall be a lien, as of the date when the agreement or petition was filed with the prothonotary. Pending the approval of the agreement or the award of compensation, no other lien which may be attached to the employer's property during such time shall gain priority over the lien of such agreement or award; but no execution shall issue on any compensation judgment before the approval of the agreement or the award of compensation on the said petition.
