Third party claims to debt of garnishee
18If anyone other than the judgment creditor or judgment debtor claims to be entitled to the debt or sum of money owing from the garnishee, by assignment thereof or otherwise, the judge when adjudicating in any of the cases aforesaid, or by calling the proper parties before him by summons for the purpose, may enquire by affidavits or oral testimony into and decide upon such claim, and allow to give effect to it, or hold it void as against the judgment creditor for being a fraud upon creditors or otherwise as the justice of the case requires, and for such purpose he may require the attendance of such parties and such witnesses, their fees for attendance being first paid, as he thinks necessary.
