Signature Verification Procedures for Initiative, Referendum, New Party, and Independent Candidate Petitions
PURPOSE: The secretary of state may make rules to ensure
uniform, complete, and accurate checking of initiative and
referendum petition signatures. This rule provides for uniform
determination of whether signatures are those of legal voters as
required in Article III, Section 50 of the Missouri Constitution.
(1) Voter signatures will be rejected if—
(A) They list an address outside of the county as indicated on
the petition except as provided in subsection (2)(B) and (3)(F) of
this section; or
(B) They have been struck through or crossed out.
(2) Voter names will only be accepted if—
(A) The name is exactly as it appears on the voting rolls
except that there is—
1. The presence or absence of a middle initial when a first
name is given or the presence or absence of a first initial when
a middle name is given;
2. The substitution of a common nickname for the name
on the voting roll, that is, Dick for Richard, Liz or Beth for
Elizabeth, Bill for William, Becky for Rebecca, etc.;
3. The presence or absence of terms such as Jr. or Sr.
following a name;
4. The use of only a first and middle initial provided that
on either the petition or the voting rolls both initials can be
determined from the name(s) given; and
5. A name change and the local election authority determines that the individual’s signature on the petition and on
the voter’s registration record are sufficiently alike to identify
the petition signer as the same person who is registered to
vote; and
(B) They were registered to vote within the county named
at the top of the petition page on the date the petition was
signed.
(3) Voter addresses will be accepted if they meet one (1) or a
combination of the following categories:
(A) The address is exactly as it appears on the voting rolls;
(B) The address is exactly as it appears on the voting rolls
except that there is—
1. The presence or absence of a letter or number identifying
an apartment; and
2. The presence or absence of a letter or grouping of letters
indicating the directional location of a street, for example, “E”
for east, “NW” for northwest, “S” for south;
(C) The voter resides in the same residence as indicated on
the voting rolls and the local election authority can determine
that only the address designation has been changed by
municipal or postal authorities;
(D) The address as listed on the petition was the voter’s
registered address on the date the petition was signed;
(E) The address listed on the petition is different from the
address on the voting rolls but within the county named at
the top of the page, provided that the local election authority
who maintains the registration record of such person shall
compare and determine that the individual’s signatures on the
petition and on the voter’s registration record are sufficiently
alike to identify the petition signer as the same person who is
registered to vote within the jurisdiction. If otherwise valid, the
signature of an individual whose address is acceptable under
this subsection (3)(E) shall be counted in the totals of the local
election authority who has jurisdiction over the address listed
on the petition; or
(F) The address listed on the petition is different from the
address on the voting rolls but the voter was registered to vote
within the county named at the top of the page on the date the
petition was signed, provided that the local election authority
who maintains the registration record of such person shall
compare and determine that the individual’s signatures on the
petition and on the voter’s registration record are sufficiently
alike to identify the petition signer as the same person who
was registered to vote within the jurisdiction on the date the
petition was signed. If otherwise valid, the signature of an
individual whose address is acceptable under this subsection
(3)(F) shall be counted in the totals of the local election
authority who has jurisdiction over the address named at the
top of the petition page.
(4) A voter’s signature will be accepted as valid if it generally
appears to be in a form similar to that found on the voter rolls.
(5) In order for a name to be qualified to appear on the petition,
there must be a valid voter name, address, and signature.
NOTE: Failure of any other information is not a reason to fail to
certify a name as being qualified.
(6) A voter’s signature shall not be deemed invalid on the basis
of source of registration. If otherwise valid, the signature of a
person who registered to vote pursuant to the provisions of
sections 115.159, 115.160, or 115.162, RSMo, shall be accepted as
valid without respect to whether such person has previously
voted in the jurisdiction or received a voter identification card,
provided that each of the following must apply at the time of
verification of the petition by the local election authority:
(A) The voter registration application had been received and
accepted by the election authority on or before the date the
petition was signed;
(B) The verification notice sent by the election authority
pursuant to section 115.155.3, RSMo, was not returned by
the postal service to the election authority within the time
established by the election authority; and
(C) The local election authority’s voter registration file
reflects the applicant was eligible to vote in the county named
at the top of the petition page on the date the petition was
signed.
