  any moneys to a corporate or other  agency  or  instrumentality  of  the
  state for a public purpose, any reasonable expenses necessarily incurred
  by  such  an  agency  or  instrumentality  in compelling or enforcing by
  judicial proceeding payment to it of  such  moneys  shall  be  a  charge
  against  such municipal corporation and such municipal corporation shall
  be liable therefor and shall pay the amount thereof  upon  certification
  and approval by the attorney-general, to such agency or instrumentality,
  provided  vouchers therefor, properly certified and approved as required
  by this section, shall be presented to and filed with the  chief  fiscal
  officer  of  the  municipal  corporation  within  six months after final
  determination of such judicial proceedings  in  the  case  of  any  such
  expenses  hereafter  incurred,  and  in  the  case  of any such expenses
  heretofore incurred within six months after this section as hereby added
  takes effect.  The provisions of this section shall apply to and in  the
  case  of  such expenses heretofore incurred subsequent to January first,
