If any Person against whom the Metropolitan Board of Works, or any District Board or Vestry, have any Claim or Demand, become bankrupt, or take the Benefit of any Act for the Relief of Insolvent Debtors, it shall be lawful for the Clerk or Collector, in all Proceedings under the Bankruptcy or Insolvency, to represent such Board or Vestry, and act in their Behalf in all respects as if such Claim or Demand were the Claim or Demand of the Clerk or Collector, and not of such Board or Vestry.
