- Scenario
- Signing a document that appears to require a notary's presence and seal.

- The user needs to confirm the legal validity of electronic signatures for documents requiring notarization before proceeding with the signing process.
Before signing your document electronically, carefully read the document's specific signing instructions and determine the jurisdiction or state laws that govern it.
Verify Legal Requirements and Consult a Notary
Determine the legal validity of an e-signature by checking local jurisdiction laws and consulting with the relevant legal authority.
The legal validity of an electronic signature and notarization requirements heavily depend on the laws and regulations in your specific country or state.
Many jurisdictions require certain documents—like property deeds, wills, or sworn affidavits—to be signed in the physical presence of a notary public, making standard electronic signatures invalid for these specific cases.
Review the document's instructions or terms to see if an 'in-person' or 'wet signature' is explicitly required by the issuing authority.
Contact the notary public, the agency requesting the document, or a qualified legal professional in your jurisdiction to confirm if an e-signature is legally acceptable.
Ask your notary or legal advisor if your state or country permits Remote Online Notarization, which allows electronic signing while a licensed notary observes via a secure webcam connection.

Frequently Asked Questions
What is the difference between an electronic signature and a digital signature?
An electronic signature is a digital representation of a person's intent to sign a document, such as a typed name or a drawn signature. A digital signature is a specific type of electronic signature that uses cryptographic technology and digital certificates to authenticate the signer's identity and ensure the document hasn't been altered.
Can I notarize a document online?
Yes, many jurisdictions now support Remote Online Notarization (RON). This allows you to sign a document electronically while a licensed notary verifies your identity over a secure, recorded video call and applies a digital notary seal.
Are electronic signatures legally binding for all documents?
In most countries (under laws like the ESIGN Act in the US or eIDAS in the EU), electronic signatures are legally binding for general business agreements, contracts, and personal documents. However, highly regulated documents like wills, trusts, and real estate transfers often still require wet signatures or specific notarization.
How do I securely share a signed PDF in WPS Office?
Once you have signed your document in WPS Office, you can encrypt it with a password by going to the 'Protect' tab and selecting 'Encrypt'. This ensures that only authorized recipients can open and view your signed PDF.
