I had a short notice to sign documents and return via overnight express mail. When I got this notice, I was in a doctors appointment which ended at 12:30 PM. I searched for mobile notaries and the Opal group kept popping up with good reviews. I filled out the form and within 2 minutes they contacted me, set up an appointment to meet at my house at 3:30, the Notary was five minutes early, she noticed a couple of items that were not identified to be completed in the instructions, we contacted my lawyer and cleared it up, she notarized six documents, and was out the door before 4. I had enough time to overnight it with no issues. I will definitely hire them again, and highly recommend.
