Section 5-456. Taxation of costs, charges and expenses

a. The costs or
  charges of any agency of the city, or others, which shall be required by
  law to be taxed, shall not be paid or allowed for any service  performed
  under  this  subchapter,  unless the same shall be taxed by the court. A
  bill of such costs, charges and expenses shall be filed in the office of
  the clerk of the court in the county in which the land  is  situated  at
  least  ten  days  before  the  same shall be presented for taxation, and
  there shall be annexed thereto a  statement  of  the  amounts,  if  any,
  previously  taxed,  to  whom  the same were payable and the date of such
  taxation. A notice shall be published in the City Record, for ten  days,
  of  the time and place of taxing such costs, charges and expenses, which
  shall be thereupon taxed by a justice of the  supreme  court,  or  by  a
  referee under his or her special order.
    b.  All  such  costs  and expenses or disbursements shall be stated in
  detail in the  bill  of  costs,  charges  and  expenses,  and  shall  be
  accompanied by such proof of the reasonableness and necessity thereof as
  is  now  required  by law and the practice of the court upon taxation of
  costs and disbursements in other special proceedings or actions in  such
  court.
