Quick Summary
The legal validity of electronic signatures on notarized documents depends on two separate tests: the signature must meet electronic-signature rules, and the notarial act must meet notary and commissioning rules. Both must pass, because a valid e-signature means nothing if the notarial act itself was flawed.
- Electronic signing, electronic notarization and remote online notarization are three distinct things, not the same process.
- A valid notarized e-document needs a reliable signature, clear intent, verified identity and an intact record.
- Ask for the audit trail, not just the sealed PDF, since disputes are won on process.
- Many provinces still require wills to be signed in the physical presence of witnesses.
- Electronic signatures do not expire on their own unless the document or receiving party sets a limit.

Legal Validity of Electronic Signatures on Notarized Documents
Can a notarized document be signed and sealed online? Yes.
This guide from The Online Notary breaks down how those two tests work in practice.
Here is the core tension most guides skip: a valid e-signature means nothing if the notarial act itself was flawed.
Below, we cover the requirements, the documents that cannot be signed electronically, how remote notarization works, and what evidence you need if a dispute arises.
Can an Electronic Signature Be Notarized?
An electronic signature can be notarized, provided the notary performs a valid notarial act and the signature meets electronic-signature requirements.
A common mistake is treating "e-signature" and "e-notarization" as the same thing. They are not.
- Electronic signing is how a person marks assent to a document.
- Electronic notarization is how a notary confirms identity and witnesses or certifies the act.
- Remote online notarization is e-notarization performed over live video rather than in person.
You can have a perfectly valid e-signature on a document that fails as a notarized record because the notary skipped a step. That is where disputes start.
Requirements for a Valid Electronic Signature and Notarial Act
A valid notarized e-document needs four things: a reliable signature, clear intent to sign, verified signer identity, and an intact record. Miss one and enforceability is at risk.
Most provincial and federal electronic-signature rules follow a similar logic. The signature must be reliable and linked to the signer. The notary must properly identify the person and record the act. Let's take the two halves in turn.
Consent, Intent to Sign, and Proof of Assent
Consent and intent are where documents quietly fail. The signer must clearly intend to sign and agree to do business electronically.
What counts as proof of assent:
- An explicit consent step before signing
- A recorded click or action showing intent
- A witnessed verbal confirmation during the video session
A notary who cannot show intent has a weak record. In practice, this means the platform must capture consent as data, not just assume it.
Signer Identity, Authentication, and Document Integrity
Identity verification is the backbone of a defensible notarial act. The notary must confirm the signer is who they claim to be.
Strong practice combines several checks:
- Government photo ID reviewed on camera
- Knowledge-based or document-based verification
- A live video comparison of face to ID
Document integrity matters just as much. If the file can be altered after the notary signs off, the record loses value. A digital seal and audit trail protect against that.
Remote Online Notarization: How It Works and Where It Is Accepted
Remote online notarization is a live video session where a commissioned notary verifies your identity and completes the notarial act without you leaving home.
The step-by-step workflow
Most platforms follow the same sequence. Knowing it in advance is the best way to avoid a rejected document.
- Book and confirm eligibility. Confirm the document type is eligible and that the receiving party accepts remote notarization. This is the step people skip, and it is the one that causes the most rework.
- Complete identity verification. Expect a government photo ID check, a live video comparison of your face to the ID, and often a knowledge-based or document-based challenge. The notary must be satisfied you are who you claim to be.
- Capture consent and intent. You will be asked to consent to doing business electronically and to confirm your intent to sign. This consent is recorded as data in the audit trail, not just assumed.
- Join the live session. The notary witnesses the signing in real time over video. For documents requiring witnesses, the witness joins the same session or a linked session, depending on the platform and the provincial rule.
- Apply the notarial seal. The notary completes the notarial certificate and applies a digital seal. The seal is tamper-evident: if the document changes after sealing, the seal breaks.
- Retain the record. The platform stores an encrypted copy of the sealed document and the full audit trail. You should download both.
What the audit trail should contain
The audit trail is the evidence file. A defensible one captures, at minimum:
- Timestamps for each step, including the identity check and the signing
- The identity-verification method and result
- The consent and intent records
If a platform cannot produce these on request, the record is weaker than it looks.
Where it is accepted
Acceptance varies by receiving party, not just by province. Many banks, government offices, and courts accept remotely notarized documents, but some institutions still ask for specific formats, a wet-ink original, or additional proof. Always confirm the receiving party's requirements before you book, a document that is validly notarized can still be refused by an institution with its own policy.
At The Online Notary, our commissioned and licensed Canadian notaries run sessions from 7am to 11pm, including evenings and weekends.
Documents That Cannot Be Electronically Signed
Some documents cannot be electronically signed, and no platform changes that. The exceptions are narrower than most people assume, but they are real, and they cluster around documents where the law prescribes a specific formal method, usually wet ink, physical presence, or in-person witnessing.
Here is the document-by-document picture for the categories readers ask about most. Rules vary by province and by the specific statute, so treat this as a starting checklist, not a substitute for confirming the governing rule.
Wills and estate instruments
This is the most restrictive category. Many provinces still require a will to be signed in the physical presence of witnesses, and some require the witnesses to sign in the testator's presence. Electronic signing and remote witnessing have been expanded in some provinces on a temporary or permanent basis, but the rules are not uniform. A will signed electronically without confirming the current provincial rule is one of the most common sources of estate litigation.
Powers of attorney
Powers of attorney for property and for personal care are treated differently in different provinces. Some provinces permit electronic signing with witnessing requirements; others require a traditional signature and, in some cases, a specific form. Because a power of attorney is often challenged after the grantor loses capacity, the formalities matter more here than almost anywhere else.
Affidavits and sworn statements
Affidavits are commissioned, not just notarized, and the commissioning rules govern. Many provinces now permit remote commissioning and electronic affidavits, but the affidavit must still be sworn or affirmed, and the commissioner must be satisfied of the deponent's identity. Court rules can impose additional requirements, some courts require a specific jurat form or a wet-ink original for filing.
Real-estate instruments
Land-title documents are governed by the provincial land registry. Most provinces have moved to electronic registration, but the signing and witnessing requirements for the underlying instruments are set by the land titles act and registry practice. Confirm with the registry or your lawyer before signing a transfer or mortgage electronically.
Court and government forms
Some agencies mandate paper or a specific electronic filing portal. A general e-signature law does not override an agency-specific form requirement. If a form says 'original signature required,' that instruction controls.
Documents requiring in-person witnessing by law
Where a statute requires a witness to be physically present, remote witnessing does not satisfy it unless the province has specifically authorized remote witnessing. This is the single most common reason a remotely notarized document is rejected.
Do Electronic Signatures Expire?
Electronic signatures do not expire on their own. A valid signature remains valid unless the document itself sets an expiry, the underlying law requires re-execution, or the receiving party imposes a time limit.
What can create a practical deadline:
- The document states a validity period
- A government form must be submitted within a set window
- The institution requires a recent notarization date
So the signature does not "go bad." But the acceptance of the document might depend on timing. Keep your audit trail and sealed copy for as long as the document could be challenged.
Cross-Border Acceptance and Evidence for Disputes
Cross-border acceptance is the hardest question, and it deserves a direct answer.
For documents heading abroad, build a strong evidence file.
Your evidence checklist:
- The sealed, final electronic document
- The full audit trail with timestamps
- Record of the identity verification steps
A common mistake is sending only the signed PDF and leaving the audit trail behind.
For current rules and any temporary measures, check the official source for your province or the receiving country, since these can change. Government of Canada guidance on electronic signatures and digital records is a reasonable starting point for federal context, and provincial regulators publish their own notary and commissioning rules.

Frequently Asked Questions
Are electronic signatures legally binding on notarized documents?
In most cases, yes. Provincial electronic commerce legislation and the federal Personal Information Protection and Electronic Documents Act recognize electronic signatures where the parties consent and the signature reliably identifies the signer and links them to the document. A notary can complete the notarial act electronically, including identity verification and witnessing, and attach a digital seal. The main exceptions are documents the law excludes from electronic form, such as certain wills, powers of attorney, and some court filings. Check the specific provincial rules that apply to your document before you sign.
Can an electronic signature be notarized by video?
Yes, through remote online notarization. The notary verifies your identity using government-issued photo ID and, where required, knowledge-based checks, watches you sign or acknowledge the document on camera, and applies a tamper-evident digital seal with an audit trail. The resulting notarized document is generally accepted by banks, government offices, and immigration authorities when the notary's commission and the province's rules are followed. Confirm the receiving institution's format requirements before booking, since some still ask for a printed copy with a wet-ink seal.
Do electronic signatures expire?
The signature itself does not carry an expiry date. What matters is the validity of the underlying document and, for notarized records, the notary's commission at the time of signing. A digital certificate used to apply a cryptographic signature may have a defined validity period, but that does not invalidate a document signed while the certificate was active. Retention rules and the receiving institution's acceptance window are the practical limits. Keep your audit trail and sealed copy for as long as the document could be challenged.
Which documents cannot be electronically signed?
Provincial rules typically exclude wills, codicils, and certain powers of attorney from electronic signing, and some land transfer and court documents have their own requirements. Federally, the Canada Evidence Act and provincial evidence acts set out specific exclusions. If your document falls into an excluded category, a notary cannot make it valid by adding an electronic signature. Ask the notary to confirm eligibility before your appointment, and keep a wet-ink original where the law or the receiving institution requires one.
