How Electronic Signatures Work (And How to Send One for Signing)

Sending a document for electronic signature follows roughly the same steps across most e-signature tools. Here is the general process, plus how the legal side actually works.

  1. Upload the document

    Start by uploading the file you need signed β€” usually a PDF or Word document β€” into the e-signature platform.

  2. Add recipients

    Enter each signer's name and email, and set a signing order if multiple people need to sign in sequence rather than all at once.

  3. Place signature fields

    Drag signature, date, initial, and text fields onto the document at the exact spots each signer needs to complete.

  4. Send for signature

    The platform emails each recipient a secure link. They open it, review the document, and complete their assigned fields β€” most tools do not even require the signer to have an account.

  5. Track progress and receive the completed copy

    The sender can see who has signed and who has not. Once everyone finishes, all parties automatically receive the final signed document along with a certificate or audit trail showing each signature's IP address, timestamp, and authentication method.

What makes an electronic signature legally valid

In the US, the federal ESIGN Act and UETA (adopted by most states) give electronic signatures the same legal weight as handwritten ones for most contracts, as long as all parties consented to sign electronically. The EU's eIDAS regulation similarly recognizes electronic signatures, using tiered categories β€” simple, advanced, and qualified β€” that carry different levels of legal weight depending on the use case. Many other countries have adopted broadly similar frameworks, though the specifics vary, so it's worth checking local requirements for anything with high legal or regulatory stakes.

What an e-signature platform actually proves

Beyond capturing the mark itself, these platforms build an audit trail: who accessed the document, when, from what IP address, and what authentication step β€” like email verification or an SMS code β€” confirmed their identity. That trail is often more important for enforceability than the signature's visual appearance, since it demonstrates consent and identity in a way a simple scanned image cannot.

Frequently Asked Questions

Are electronic signatures accepted for every type of document?

No. Most everyday contracts and agreements qualify, but many jurisdictions still require a traditional wet-ink signature β€” and sometimes notarization β€” for specific documents like wills, certain real estate transfers, or court filings. Check local law for anything high-stakes.

Do I need to pay for an e-signature tool to sign one document?

Most major e-signature platforms let you sign a document you receive for free, without needing an account. A paid plan is typically only necessary if you're the one regularly sending documents out, or need features like bulk sending and API access.
