  54. Registration of marriage solemnized
  
  under Part V
  After the
  
  solemnization of any marriage under this Part, the Marriage Registrar present at
  
  such solemnization shall forthwith register the marriage in duplicate ; that is
  
  to say, in a marriage-register-book, according to the form of the Fourth
  
  Schedule hereto annexed, and also in a certificate attached to the
  
  marriage-register-book as a counterfoil.
  The entry of such
  
  marriage in both the certificate and the marriage-register-book shall be signed
  
  by the person by or before whom the marriage has been solemnized, if there be
  
  any such person, and by the Marriage Registrar present at such marriage,
  
  whether or not it is solemnized by him, and also by the parties married, and
  
  attested by two credible witnesses other than the Marriage Registrar and person
  
  solemnizing the marriage.
  Every such entry shall
  
  be made in order from the beginning to the end of the book, and the number of
  
  the certificate shall correspond with that of the entry in the
  
  marriage-register-book.
