Section 1303. Jury trial; how obtained; jury fee

(a) Either party after
  joinder of issue may demand a trial by jury.  The demand must be made in
  writing and must be filed with the clerk with the notice  of  trial  set
  forth in § 1301. Any other party to the action within ten days after the
  service  of  a  copy  of the notice of trial upon him unaccompanied by a
  written notice demanding a trial by jury, may serve upon  the  attorneys
  for  all  the  other  parties to the action a written notice demanding a
  jury trial and file a copy of such notice with the  clerk  within  three
  days   after  service  thereof.  In  a  summary  proceeding  to  recover
  possession of real property, the demand may be made by the tenant at the
  time of answering or by the landlord at  any  time  before  the  day  of
  trial.
    (b)  Unless  a  demand  is  made  and the jury fee paid as provided in
  section nineteen hundred eleven of this act, a jury trial is waived.
    (c) The Court may relieve a party from the effect of failing to comply
  with this section if no undue prejudice to the rights of  another  party
  would result.
