Editing & Signing
Are Electronic Signatures Legally Binding?
A plain-English look at where electronic signatures are recognised, what makes one hold up, and the documents that still need ink.
In most of the world, yes — electronic signatures have been recognised in law for over two decades. The interesting questions are which documents are excluded, and what makes a particular signature defensible if it is ever challenged.
This is general information rather than legal advice. For a specific transaction, ask a lawyer in the relevant jurisdiction.
The main legal frameworks
| Region | Law | Position |
|---|---|---|
| United States | ESIGN Act (2000) and UETA | Electronic signatures have the same effect as handwritten ones |
| European Union | eIDAS Regulation | Recognised, with three tiers of increasing assurance |
| United Kingdom | Electronic Communications Act and UK eIDAS | Valid for most contracts |
| Canada | PIPEDA and provincial acts | Recognised |
| Australia | Electronic Transactions Act | Recognised |
| India | Information Technology Act | Recognised, with requirements for certain classes |
What usually still needs ink
- Wills and testamentary documents in many jurisdictions.
- Some property transfers and deeds.
- Certain court filings and notarised instruments.
- Some family law documents — adoption, divorce papers.
- Specific regulated forms that name a wet signature explicitly.
These exclusions vary considerably by jurisdiction and change over time. Where a document falls into one of these categories, check rather than assume.
Making a signature defensible
- 1Keep the email trail showing the document was sent and returned.
- 2Record the date on the document itself, next to the signature.
- 3Make sure both parties hold the identical final file.
- 4Use a digital signature where the value or the risk justifies it.
- 5Do not alter the document after signing — any change undermines the record.
The tiers under eIDAS
EU law distinguishes simple electronic signatures, advanced ones (uniquely linked to the signer and capable of detecting change), and qualified ones (advanced, plus a qualified certificate from an accredited provider). Only qualified signatures are automatically equivalent to handwritten across all member states; the others are admissible and their weight is assessed on the evidence.

Open Sign PDFFrequently asked questions
Is a typed name a legal signature?+
It can be, where intent to sign is evident. It carries less evidential weight than a drawn signature or a digital one.
Does a PDF signature hold up in court?+
Electronic signatures are admissible in most jurisdictions. How much weight one carries depends on the surrounding evidence.
Do both parties have to sign electronically?+
No. Mixed signing is common and does not invalidate an agreement.
Which documents cannot be signed electronically?+
Commonly wills, some deeds and certain court documents — but the list varies by jurisdiction, so check for your specific case.
