When you need this office
If your document was notarized by a notary commissioned in Montgomery County, this clerk must authenticate the notary's signature before the Maryland Secretary of State will add an apostille. The county is printed on the notary's stamp. Signing in Rockville doesn't matter on its own; what counts is where the notary holds their commission.
The Montgomery County clerk also keeps the county's marriage license records and divorce cases. Certified copies of those records are signed by the clerk and go straight to the Secretary of State, so you can usually apostille them yourself.
