Abstract
This study indicates the legal nature of a testimony as a duty and not
as right. To sustain a testimony as a means of proof, it shall be given
under oath. The Anglo- American law differs from the Jordanian law
in which under the former a testimony shall be attached with an
affirmation.
This study also deals with the witness’s age and the relation between
this age and the understanding of the nature of oath. It also addresses
the following matters: the legal status of a witness who refuses to give
a testimony, unsown testimony, the testimony given by certain
persons against each other such as ; ancestors and descendants, and
spouses , the classification of the testimony into eye testimony and
hearsay testimony, the convincing testimony and the discretionary
power of the court with respect to such matters, giving a false
testimony, and inconsistency between the parts of the given testimony
