A commissioned notary public is who can notarize a lease agreement in almost every case, and they’re the official you’ll find at banks, shipping stores, and real estate offices. Judges, court clerks, some attorneys, and designated military legal personnel also hold notarial authority under specific circumstances. Before you book an appointment, know that most standard residential leases in the United States don’t actually require notarization to be legally binding; the process matters when a long-term lease will be recorded with the county, when state law demands it, or when the landlord insists on it.
Who Holds the Authority to Notarize
A notary public is an individual commissioned by their state government to serve as an impartial witness to document signings. Their authority is limited to the state that commissioned them, and they’re required to keep a journal of every notarial act they perform. For a typical lease, this is who you’re looking for.
Other officials can notarize documents by virtue of the office they hold. Court clerks and judges in many jurisdictions have notarial powers and can authenticate signatures connected to judicial or administrative matters. Attorneys in some states are authorized to notarize documents, though the rules on this vary from state to state.
Military-connected signers have a separate path. Under federal law, judge advocates, civilian legal assistance attorneys, adjutants, and designated military paralegals can perform notarial acts for service members, military dependents, and others eligible for military legal assistance. This authority extends to personnel stationed overseas, which matters when a service member needs to sign a lease back home while deployed.1Office of the Law Revision Counsel. 10 USC 1044a – Authority to Act as Notary
When a Lease Actually Needs to Be Notarized
Most people assume notarization is a legal requirement for any lease. It usually isn’t. A lease is a contract, and contracts are generally valid when signed by the parties involved. The statute of frauds in most states requires leases longer than one year to be in writing and signed, but “in writing and signed” is not the same thing as “notarized.” Notarization adds a layer of identity verification on top of the signature; in states where it isn’t required, it doesn’t make the contract itself more legally valid.
A few situations do call for it:
- A handful of states require notarization for residential leases that exceed a certain duration, often one year.
- Some states impose stricter requirements on commercial leases regardless of length.
- If either party wants to record the lease, or a memorandum of the lease, with the county recorder’s office, notarization is almost always a prerequisite. County recorders generally reject documents that lack a proper notarial acknowledgment.
- Landlords and property management companies sometimes make notarization a condition of the lease even when state law doesn’t. This is especially common with commercial leases and multi-year residential agreements.
If your lease or your landlord requires it, treat it as mandatory even if your state doesn’t.
Who Cannot Notarize Your Lease
A notary cannot notarize a document in which they have a personal or financial interest. A landlord who happens to be a commissioned notary cannot notarize their own lease. The same restriction applies if the notary is named anywhere in the document as a party, beneficiary, or guarantor, or if they stand to receive a commission or bonus tied to whether the transaction goes through. The regular fee for performing the notarization doesn’t count as a disqualifying financial interest; anything beyond that does.
It also helps to know what the notary isn’t doing for you. A notary verifies identity and witnesses the signing. They do not review the lease for fairness, confirm that the rent is reasonable, or check whether the terms comply with local tenant protection laws. A notarized lease with an illegal clause is still a lease with an illegal clause.
A notary who is not also a licensed attorney cannot give legal advice about the document they’re notarizing. They can’t explain what a provision means, suggest changes to the lease language, or recommend which type of notarial certificate you need. In many states, doing so constitutes unauthorized practice of law and can result in criminal penalties. If you need help understanding your lease, hire an attorney separately from the notarization.
What to Bring and How to Prepare
Every signer must present valid, government-issued photo identification. The most universally accepted forms are a state-issued driver’s license, a U.S. passport, or a military ID card. The ID must be current and not expired. Social Security cards, credit cards, and birth certificates are not acceptable because they lack a photograph.
Bring the complete lease agreement, but do not sign it beforehand. The notary needs to watch you sign. If the document arrives already signed, the notary cannot notarize it as an acknowledgment in some states, and in others the process changes significantly. Leave every signature line blank until you’re in the notary’s presence and they instruct you to proceed.
All signers must appear before the notary. If your landlord is across the country, they’ll need to visit a separate notary in their location, and the notary will attach their own certificate to the document. When multiple signers can’t be in the same room, each signer’s notarization is handled independently.
Expect the notary to examine your ID, briefly assess that you appear to understand what you’re signing and are acting voluntarily, watch you sign, complete the notarial certificate with their seal and signature, and record the transaction in their journal. If something seems off to the notary (visible confusion, signs of intoxication, apparent pressure from another party), a careful notary will decline to proceed.
Where to Find a Notary
Banks and credit unions are the most convenient starting point. Many offer free notarization to account holders, especially for straightforward documents like leases. If you don’t have an account, the fee is typically modest. Call ahead; not every branch has a notary on site every day.
Shipping and packing stores, real estate offices, and law firms commonly have notaries on staff. Real estate offices are particularly used to handling lease-related documents and tend to have someone available during business hours. Some public libraries offer free notary services to residents, though these often come with restrictions. Libraries may decline to notarize real estate documents, require appointments, or limit the number of signatures per visit.
Mobile Notaries
A mobile notary travels to your location, which is useful when multiple signers can’t easily get to the same office. The per-signature fee stays the same as any other notary, but mobile notaries charge a separate travel fee on top of it. Travel fee regulation varies widely. A few states set specific mileage rates, several others tie travel fees to the federal mileage reimbursement rate, and many states leave travel fees unregulated as long as the amount is agreed upon before the appointment. Expect to pay significantly more for a mobile notary than for walking into a bank, especially for after-hours or weekend appointments.
Remote Online Notarization
As of early 2025, 45 states and the District of Columbia have enacted permanent laws allowing remote online notarization. RON lets signers appear before a notary over a live audio-video connection instead of sitting in the same room. The notary verifies identity through a combination of knowledge-based authentication questions, credential analysis of uploaded identification documents, and visual comparison during the video call.
The session is recorded, and the notary applies a digital seal and electronic signature to the document. The signer typically uses an electronic signature as well. RON platforms must meet state-specific security and technology standards, and notaries who perform online notarizations need a separate authorization beyond their standard commission.
RON is particularly useful for lease signings where the landlord and tenant are in different cities or states. Since the notary’s authority in a RON session is governed by the state where the notary is commissioned, not where the signer is located, one notary can serve signers anywhere in the country as long as their state’s RON law permits it. If you plan to record the lease, confirm that your county recognizes RON documents.
What It Costs
Most states cap the fee a notary can charge for each signature or notarial act. For standard in-person notarizations, the statutory maximum ranges from around $2 to $25 per signature depending on the state, with $5 to $10 being the most common cap. About ten states have no statutory maximum at all, leaving fees to the market. A typical lease with two signers each signing once means two notarial acts, so double the per-signature fee.
Remote online notarization fees run higher, with state caps typically ranging from $5 to $30 per signature. Several states allow additional technology or platform fees on top of the base notarization fee, which can push the total cost of an online session well above what you’d pay in person.
Travel fees for mobile notaries, platform fees for online sessions, and any convenience charges are almost always separate from and not subject to the per-signature caps. The notary must disclose these additional charges before performing the service.
If the Notarization Turns Out to Be Defective
A notary who cuts corners creates real problems for the parties relying on the document. If a county recorder’s office spots a defective notarial certificate, it will reject the lease for recording. If the notarization is challenged in court, the document’s authenticity comes into question, and a judge may find it unenforceable.
Notaries themselves face serious consequences for misconduct. States impose fines, suspension, or permanent revocation of a notary’s commission for violations like failing to verify identity, notarizing without the signer being present, or notarizing a document in which the notary has a financial interest. In many states, knowing or willful notarial misconduct is a criminal offense carrying fines and potential jail time.
For the lease parties, the practical fix is to have the document re-notarized correctly. This usually means all signers appearing before a new notary and going through the full process again. If you suspect a notarization was improperly performed, address it before relying on the document in a transaction or filing it with any government office.
