# What Is In-Person Electronic Notarization (IEN)? How It Works in the Philippines


**In-Person Electronic Notarization (IEN)** is a form of [e-notarization](/blog/glossary/e-notarization/) where the principal (signer) and any witnesses **physically appear** before an [Electronic Notary Public (ENP)](/blog/glossary/electronic-notary-public/), but the document being notarized is in electronic format (PDF/PDF-A) rather than paper.

## How IEN Differs from Traditional Notarization

IEN maintains the same physical presence requirement as traditional notarization -- the key difference is the document format and security technology used.

| Aspect | Traditional Notarization | In-Person Electronic Notarization |
|--------|------------------------|----------------------------------|
| Physical presence | Yes | Yes |
| Document format | Paper | PDF / PDF-A |
| Signature method | Wet ink | [Electronic](/blog/glossary/electronic-signature/) or [digital signature](/blog/glossary/digital-signature/) |
| Notarial seal | Physical rubber stamp | [Electronic notarial seal](/blog/glossary/electronic-notarial-seal/) |
| Record-keeping | Physical [notarial book](/blog/glossary/notarial-book/) | Electronic notarial book |
| Audit trail | Manual log entry | Automated, tamper-proof [audit trail](/blog/glossary/document-audit-trail/) |
| Verification | Visual ID check | Multi-factor authentication |

## How IEN Works

1. **Physical appearance** -- The principal and witnesses appear in person before the ENP
2. **Identity verification** -- Even though the parties are physically present, the ENP verifies identity through multi-factor authentication (government ID + biometrics) via the [ENF platform](/blog/glossary/electronic-notarization-facility/)
3. **Document review** -- The ENP reviews the electronic document (PDF/PDF-A) on the ENF platform
4. **Electronic signing** -- The principal applies their electronic or digital signature to the document
5. **Notarial act** -- The ENP administers the oath or receives the acknowledgment
6. **Seal application** -- The ENP applies their [electronic notarial seal](/blog/glossary/electronic-notarial-seal/) and signature
7. **Recording** -- The act is recorded in the electronic notarial book and uploaded to the SC database

## When to Use IEN vs. REN

IEN is appropriate when:
- Parties are **in the same location** as the ENP
- The principal **prefers face-to-face** interaction for the notarial act
- The document type requires or benefits from in-person verification
- Physical presence adds **comfort or trust** to the transaction

[Remote Electronic Notarization (REN)](/blog/glossary/remote-electronic-notarization/) is better when:
- Parties are in **different locations**
- The principal is an **OFW** at a Philippine mission abroad
- **Travel to the ENP's office** is impractical or costly
- Speed and convenience are the **primary considerations**

Both IEN and REN produce documents with the same legal effect -- the choice depends on practical circumstances.

## Benefits of IEN Over Paper Notarization

Even when parties are physically present, IEN offers advantages over traditional paper-based notarization:

1. **Better security** -- Multi-factor authentication vs. visual ID inspection; electronic audit trails vs. manual log books
2. **Fraud prevention** -- [Tamper-proof digital records](/blog/understanding-notarialos-approach-to-unbreakable-document-integrity/) vs. physical seals that can be [forged](/blog/sc-rulings-on-fraudulent-notarial-seals-and-signatures-shows-why-e-notarization-is-the-future/)
3. **Faster processing** -- Electronic document handling eliminates printing, scanning, and physical storage
4. **Centralized records** -- Automatic upload to the SC database for easy verification
5. **Document integrity** -- [Digital signatures](/blog/glossary/digital-signature/) using [PKI](/blog/glossary/public-key-infrastructure/) ensure any tampering is detectable

## Legal Basis

IEN is authorized under [A.M. No. 24-10-14-SC](/blog/glossary/am-no-24-10-14-sc/) (Rules on Electronic Notarization). The legal validity of the electronic document and signatures used in IEN is established by [RA 8792](/blog/glossary/ra-8792/) (Electronic Commerce Act).
