Illinois General Assembly - Illinois Compiled Statutes

Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process. Recent laws may not yet be included in the ILCS database, but they are found on this site as Public Acts soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the Guide.

Because the statute database is maintained primarily for legislative drafting purposes, statutory changes are sometimes included in the statute database before they take effect. If the source note at the end of a Section of the statutes includes a Public Act that has not yet taken effect, the version of the law that is currently in effect may have already been removed from the database and you should refer to that Public Act to see the changes made to the current law.

(810 ILCS 5/3-115) (from Ch. 26, par. 3-115)

Sec. 3-115.

Incomplete instrument.

(a) "Incomplete instrument" means a signed writing, whether or not
issued by the signer, the contents of which show at the time of signing
that it is incomplete but that the signer intended it to be completed by
the addition of words or numbers.

(b) Subject to subsection (c), if an incomplete instrument is an
instrument under Section 3-104, it may be enforced according to its
terms if it is not completed, or according to its terms as augmented
by completion.  If an incomplete instrument is not an instrument under
Section 3-104, but, after completion, the requirements of Section 3-104 are
met, the instrument may be enforced according to its terms as augmented
by completion.

(c) If words or numbers are added to an incomplete instrument without
authority of the signer, there is an alteration of the incomplete
instrument under Section 3-407.

(d) The burden of establishing that words or numbers were added to an
incomplete instrument without authority of the signer is on the person
asserting the lack of authority.
