Notary Boiler-Plate Wording
 
Notary wording and notary verbiage differs from state to state.  Ohio might have one type of official notary boiler-plate wording on acknowledgment certificates while California notary wording or Florida notary wording might be completely different. 
 
If you are a notary…
To find out what official notary verbiage is in your state for particular notary acts, you should ideally have acknowledgment certificate pads, as well as jurat certificate pads.
 
If you are not a notary, but need to have a document notarized…
The official notary wording from your state MIGHT be embedded in the signature section of the document already.  If not, an experienced notary in your state MIGHT (should) have official pads for common notary acts with the notary verbiage on it.
 
Is it important to have the right boiler plate wording?
Some states require exact wording, while most states require certain key pieces of information to be included in the wording.  The important facts generally are the date of the signing, the name of the notary, the name of the signer, the fact that the signer acknowledges signing the document, the fact the the signer appeared before the notary and proved his/her identity, the signature of the notary (also confusingly called a seal), and the official seal of the notary (stamp).
 
How to fill out notary certificate wording?
Leave this to the notary.  Any notary is supposed to know how to fill out the certificate wording. If you are a single man signing a document and the notary verbiage says he/her/their, then the notary is supposed to know to cross out the her and their, although many are so uneducated that they don’t cross out anything. 
 
Notary personally known wording
Many states no longer allow a notary to use personal knowledge of a signer to identify them. However, if your state allows you to identify a signer based on the signer being personally known to you, then you can indicate that on the notary wording and in your journal (if your state requires a journal).
