Electronic signature
Also known as: e-signature, electronic signature, digital signature, DocuSign, Adobe Sign
An electronic signature (e-signature) is a legally recognized way to sign documents digitally, using services like DocuSign or Adobe Acrobat Sign.
It replaces printing, signing, and scanning with a fast, secure, trackable process, speeding up contracts and approvals while creating a verifiable record of who signed what and when.
Electronic signature, explained at three levels
At home
An electronic signature is like signing a paper form, except the paper, pen and envelope are replaced by a secure website. You open a link, review the document, and click or draw your signature. Behind the scenes, the service records who signed, when, and from what device, then seals the finished document so any later change would show.
At work
An electronic signature is any electronic way of showing a person agrees to a document, from a typed name to a signature drawn on a platform like DocuSign or Adobe Acrobat Sign. Canadian law, including PIPEDA Part 2 and provincial electronic commerce acts, generally accepts them. Businesses care because contracts get signed in minutes from anywhere, with a record of who signed and when.
At home
A signing service works in steps. The sender uploads a document, places signature fields and lists signers in order. Each signer gets an emailed link, sometimes with an extra check like a code sent to their phone. When they sign, the service records the time, email address and IP address in an audit trail, often called a certificate of completion. Finally it seals the document with a digital certificate so any later edit is detectable.
At work
E-signature platforms add workflow on top of signing: reusable templates, signing order, reminders, bulk sending and integration with tools like a CRM or document management system. Identity checks can be stepped up from email alone to SMS codes, knowledge-based questions or ID document scans. The audit trail is the key legal evidence, recording each view, signature and IP address. Completed documents are stored by the platform and should also be filed in the business's own records.
At home
Two ideas often get mixed up. An electronic signature is the legal concept of agreeing electronically. A digital signature is the cryptography that makes tampering detectable: the platform computes a fingerprint of the document, called a hash, and seals it with a private key, so changing a single comma breaks the seal. Most platforms use both. While a typed name can be legally valid, in my view the audit trail and seal are what make it hold up if challenged.
At work
Assurance levels differ by legal regime. The EU's eIDAS regulation defines simple, advanced and qualified signatures. In Canada, PIPEDA Part 2 and its Secure Electronic Signature Regulations define a 'secure electronic signature' used for some federal purposes, while provincial acts govern most private contracts. Some documents, such as certain wills, land transfers and powers of attorney, may still need wet ink or specific formalities depending on the province. Governance should map each document type to its required assurance level.
Real-world examples
At home
Sophie used to mail contracts to clients and wait days for signed copies to come back. With an e-signature service, she now sends agreements electronically, clients sign from their phones in minutes, and she gets a completed, legally valid document with a full audit trail instantly.
At work
Nadia's firm handles many client agreements. Adopting an e-signature platform with templates and multi-signer routing cut their contract turnaround from a week to a day, provided audit trails for enforceability, and stored signed documents securely, while their MSP confirmed which document types still needed traditional signatures.
Common confusions
- Electronic signatures aren't legally binding — In most jurisdictions, e-signatures are legally recognized for the vast majority of documents, backed by laws granting them standing comparable to handwritten signatures. Some specific document types are exceptions.
- A typed name or pasted image is the same as a proper e-signature — Dedicated e-signature services add crucial audit trails and identity verification that establish validity. A pasted image lacks the record that makes a signature defensible if challenged.
- All documents can be signed electronically — Most can, but certain documents (which vary by jurisdiction, such as some wills or notarized items) may still require wet signatures. Knowing the exceptions avoids problems.
For analysts
E-signatures cut agreement turnaround from days to minutes while providing an audit trail that supports legal validity. Use a dedicated service (not a pasted image) for the audit trail, and confirm which document types in your jurisdiction still require traditional signatures.
History & origin
Laws recognizing electronic signatures emerged around 2000 (such as the US ESIGN Act, Canada's PIPEDA Part 2, and provincial electronic commerce acts), giving e-signatures legal standing comparable to handwritten ones. Dedicated e-signature services grew rapidly, streamlining business agreements. Adoption accelerated with remote work, as digitally signing documents became essential when in-person signing wasn't practical, making e-signatures a standard business tool.
