A person "falsely
completes" a written instrument when
- (he/she), by adding, inserting or changing
matter, transforms an incomplete written instrument into a
complete one, without the authority of anyone entitled to grant it, so
that such complete instrument appears or purports to be in all respects
an authentic creation of or fully authorized by its ostensible maker or
(he/she) signs (his/her) own name to a written instrument, thereby falsely and fraudulently representing that (he/she) has authority to sign the instrument.
