Mobile Notary, Online Notary, or Traditional Notary: When Should You Use Which?
It is 9pm and you have a document that needs a notary by morning. Or cost is the real constraint, and you need one signature witnessed for as little as possible. Or the signer is homebound and getting them anywhere is not realistic.
The choice between a mobile notary, an online notary, and a traditional notary is a practical one. Each option solves a different problem. The wrong choice costs you time, money, or both. This guide breaks down exactly when each type makes sense, what each one costs, and how to match your situation to the right option.
Key takeaways
- A traditional notary at a bank or shipping store is often the cheapest option per signature, with fees capped by state law, but only works if one is nearby and open when you need it.
- A mobile notary travels to you and adds market-rate travel fees on top of the state-capped notarial fee, making it the right call when the signer genuinely cannot travel.
- A remote online notary (RON) completes the notarization over a live video session, typically costs less than a mobile notary, and is available any hour a platform is staffed.
- For real estate closings, financial documents, and other high-stakes workflows, the security and audit trail of an online notarization platform matters as much as the convenience.
Which one fits your situation, not which is "best"
Most comparisons of notary types default to ranking them, as if one is objectively the right answer. In practice, mobile, online, and traditional notarization solve different problems, and the right choice depends on what's actually getting in your way: a document that has to be signed at 9pm, a signer who can't leave the house, or a stack of closing paperwork that needs a notary on-site at a specific address.
Here's how the three actually compare, and when each one makes sense.
Traditional in-person notary: reliable…during business hours
A traditional notary, the kind you find at a bank branch, shipping store, or law office, charges per signature, and that fee is usually capped by state law rather than set by the market. California, for example, caps the fee at $15 per signature for common notarial acts like acknowledgments and jurats, under Government Code Section 8211, according to the National Notary Association's fee guide. Most states set a similar statutory ceiling, though the exact amount varies.
The tradeoff is availability. You need to find one, get there during business hours, and hope they aren't already busy. For a single document and no urgency, this is usually the cheapest and simplest option. For anything time-sensitive or after hours, it stops being practical fast.
Mobile notary: convenience, at a premium
A mobile notary is a commissioned notary who travels to you, whether that's your home, hospital room, or office. You're still paying the state-capped fee for the notarial act itself, but travel time and scheduling flexibility get added on top as a separate market-rate fee, since travel fees generally aren't capped the way the base notarial fee is.
According to Thumbtack's notary cost data, the average notary costs $30, and most people spend between $15 and $55 total, though the price can climb past $100 depending on the document and location. Mobile appointments tend to sit toward the higher end of that range. In Florida, for instance, the base notarial fee is capped at $10, but a mobile notary there can add mileage, after-hours, and rush fees on top of it, since those travel charges fall outside the statutory cap. The same pattern shows up in most states: the notarization itself is cheap, and the travel is what costs more.
Mobile notaries make the most sense when the signer genuinely can't travel: an elderly relative, a hospital bed, a construction site closing where the paperwork has to happen on location. If getting to a notary is the actual obstacle, paying for one to come to you is a reasonable trade.
Online notary (RON): speed and access, without the travel fee
A remote online notary handles the entire notarization over a live video session, using the same identity verification and legal standards as an in-person notarization, just without anyone traveling anywhere. For a straightforward document in a state that permits RON, this is typically both the fastest and the least expensive of the three options, since there's no travel fee to add and, on most platforms, no need to schedule around business hours. On Proof's own Notarize platform, a standard notarization on the Pro plan runs $25, with $10 for each additional seal.
RON is the right call when speed or after-hours access matters more than anything else: a document due tomorrow morning, a signer in a different state or time zone than the person who needs the paperwork, or simply not wanting to build a trip to a notary into an already full day.
