Most notarizations fail for boring reasons. The document wasn't finished. Somebody's ID was in the other car. A signer thought they could join by phone. All preventable, all in the five minutes before the knock.
The short list
Your ID, physically present
Current government-issued photo ID, in hand, not a photo of it on your phone. If your name recently changed and your ID hasn't caught up, mention it when you book so the notary can tell you what they can work with.
Every signer, physically present
The notary is there to watch specific people sign. A spouse on speakerphone, a co-signer joining “in spirit,” or anyone planning to sign on someone's behalf without paperwork establishing that authority is a rescheduled appointment. If someone can't be there, say so when booking, not at the table.
The document, complete
Blank fields invite trouble. Fill in everything that's supposed to be filled in before the appointment, and leave the signature lines alone. Many document types need to be signed in front of the notary, so if you're unsure whether to pre-sign, don't — and ask when you book.
Know what you're signing
Not legally, practically. The notary will confirm which pages need which signatures, but the appointment moves faster when you've flipped through the stack once and flagged anything that looks unfinished or unfamiliar to whoever sent it to you.
The fee conversation, already had
A mobile notary's price has two parts: the notarization work and the trip to you. Get the whole number quoted before the appointment. Any notary worth booking will give it to you without being asked twice.
The one thing you can't prep
Willingness. A notary needs the signer to be signing on purpose, aware and unpressured. If the real situation is that someone's being talked into something, the appointment isn't going to fix that, and a good notary will walk away from it. If everyone's genuinely on board, you'll never notice this part happening.
