COMPETENT WITNESS. One who is legally qualified to be heard to testify in a
cause. In Kentucky, Michigan, and Missouri, a will must be attested, for the
purpose of passing lands, by competent witnesses; but if wholly written by
the testator, in Kentucky, it need not be so attested. See Attesting
witness; Credible witness; Disinterested witness; Respectable witness; and
Witness.
