As a general rule, a Notary can notarize in any county of their state of commission. A few states have some bizarre exceptions to this rule for Deeds of properties that are in the Notary’s home state. Louisiana also has a weird rule that you can only notarize in Parishes that you are commissioned in or ones with reciprocal agreements unless you have statewide jurisdiction. What does it have to be so complicated? And why can’t they have counties like normal states?
A Washington State Notary Public may Notarize in any part of the state of Washington. However, it is allowed for a Washington Notary Public to get dual commissioned as an Oregon Notary Public or an Idaho Notary Public which is very practical if you live near a state border. Notaries in Vancouver, WA often get dual commission in Oregon so that they can service a larger area. Additionally, Notaries in Spokane, WA often become dual commissioned in Idaho as an Idaho Notary Public as well.
If you are in a pinch, and someone out of state needs your Notary services, you can meet them right at your state’s border (on your side of the border) and Notarize them there. It rarely matters what state a person is notarized in, but you could lose your commission if caught notarizing outside of your state’s borders!>
