Attesting a Signature

Attestation is similar to witnessing but specifically refers to the notary confirming they saw the signature made. Oregon law treats witnessing and attesting similarly.

Protests (Negotiable Instruments)

Oregon notaries can also note a protest on a negotiable instrument (such as a dishonored check or promissory note). This is rare and specialized.
