Section 1907. Taxation of costs and disbursements

Costs, together with fees
  paid  to  the  clerk and the fee for issuing execution to the sheriff or
  marshal, must be taxed by the clerk forthwith upon rendition of judgment
  and inserted therein. Upon issuing a transcript the clerk shall  include
  therein  the  prospective  fees  of  the county clerk and sheriff. Other
  taxable disbursements shall be taxed by the clerk on two days' notice to
  be given by the party entitled thereto to the adverse party.  The  clerk
  shall  also  tax costs allowed by an appellate court and shall enter all
  items of costs and disbursements in the docket book.  All  disbursements
  taxable  on notice must be verified by affidavit. The clerk must examine
  all items presented  to  him  for  taxation  and,  before  allowing  any
  disbursements,  must  be  satisfied  that  the  items  were  necessarily
  incurred  or  that  the  services  for  which  they  are  charged   were
  necessarily performed.
