Section 123. Contents of petition; schedule

The  petition  must be in
  writing; it must be signed by the petitioner;  and  it  must  state  the
  cause  of his imprisonment, by setting forth a copy, or the substance of
  the execution, or, if there are two or more executions, of each of them.
  The petitioner must annex thereto, and present  therewith,  a  schedule,
  containing  a  just  and  true  account  of all his property, and of all
  charges affecting the same; as the property and charges existed  at  the
  time  when  he  was first imprisoned, and also as they exist at the time
  when the petition is prepared; together with a just and true account  of
  all  deeds,  securities,  books,  vouchers,  and papers, relating to the
  property, and to the charges thereupon.
