A valid signature on a petition is a signature that meets certain legal requirements as defined by each state, such that it counts toward the minimum number of valid signatures required to (a) place an initiative on the ballot, (b) a candidate's name on the ballot, or (c) move forward with the recall of an elected official.
Requirements for deeming a signature as valid differ by state. In many states, a signature is deemed valid if the signature is from a registered voter as verified by that state's list of registered voters and if the signature on the petition matches the signature on the voter's registration.
States also have different laws providing for circumstances that may cause a signature to be found invalid. In the case of duplicate signatures appearing on a single petition, in some states, one signature counts and the other(s) don't. In other states, if a voter signs more than once, none of his or her signatures count.
Additional considerations
In some states, additional factors play a role in determining whether a signature is considered legally valid. These considerations, if required by the state, include the following:
- whether the petition circulator correctly filled out the circulator affidavit or adhered to laws governing petition circulation;
- whether the petition sheet that the registered voter signed was notarized by a notary public whose notary seal was current at the time;
- whether the signature was witnessed by another individual; and
- whether signatures from voters who live in different counties are mixed on one petition sheet.
Signer intent
Signer intent is the idea that if the signature checker can reasonably conclude that a voter intended to sign a petition, that signature should count even if the signature is flawed in various ways, such as not including a date or other technical flaws.
Some states honor signer intent in checking petition signatures and other states require strict adherence to all the technical provisions the state legislature has passed governing the signature validity process.
