Section 1907. Taxation of costs and disbursements

Costs,  together  with  fees paid to the clerk and the fee for issuing
  execution to the  enforcement  officer,  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.
