Where the person liable or any other person establishes that he may be compelled to pay, at a later date, in whole or in part any such amount of compensation with regard to which such person would have enjoyed a right of subrogation pursuant to paragraphs 2 and 3 had the compensation been paid before the fund was distributed, the Court or other competent authority of the State where the fund has been constituted may order that a sufficient sum shall be provisionally set aside to enable such person at such later date to enforce his claim against the fund.
