77 Pa. Stat. § 542
The board may, if the best interest of a child or children shall so require, at any time order and direct the compensation payable to a child or children, or to a widow or widower on account of any child or children, to be paid to the guardian of such child or children, or, if there be no guardian, to such other person as the board as hereinafter provided may direct. If there be no guardian or committee of any minor, dependent, or insane employee, or dependent, on whose account compensation is payable, the amount payable on account of such minor, dependent, or insane employe, or dependent may be paid to any surviving parent, or such other person as the board may order and direct, and the board may require any person, other than a guardian or committee, to whom it has directed compensation for a minor, dependent, or insane employe, or dependent to be paid, to render, as and when it shall so order, accounts of the receipts and disbursements of such person, and to file with it a satisfactory bond in a sum sufficient to secure the proper application of the moneys received by such person.
