If two people are signing the same document, how does an Oregon Notary Charge?

As per the Oregon State’s Guide to Notaries,  the notarial fee is charged per identification per act.

Even if the notary public is using one notarial certificate, the notary public in this case is identifying and witnessing two separate executions on the document.

Reference: Oregon Secretary of State Administrative Rule OAR 160-100-0400

Example: If two people sign a parental authorisation form, the charge is $5 per identification which will add up to $10 for the form since it has signatures of both the parents.
