FALSELY MAKES

A person "falsely makes" a written instrument when

(he/she) makes or draws a complete written instrument in its entirety, or an incomplete written instrument, which purports to be an authentic creation of its ostensible maker or drawer, but which is not such either because the ostensible maker or drawer is fictitious or because, if real, (he/she) did not authorize the making or drawing thereof; 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.
