E-Signature Laws Around the World: eIDAS (SES/AES/QES) & Beyond — FAQ
E-signature laws around the world generally recognize electronic signatures, but the required signature type depends on the country, document, and risk level. Under EU eIDAS, SES, AES, and QES have different proof and identity standards. Many routine PDFs can be signed online, while regulated filings may need qualified or local methods.

What is the difference between SES, AES, and QES under eIDAS?
The difference between SES, AES, and QES under eIDAS is the level of assurance: SES is broad, AES is identity-linked and tamper-evident, and QES is the highest EU signature level. Regulation (EU) No 910/2014, commonly called eIDAS, gives QES the same legal effect as a handwritten signature in the EU.
Article 3 of eIDAS defines electronic signatures, advanced electronic signatures, qualified certificates, and qualified electronic signatures. Article 25 says an electronic signature can't be denied legal effect just because it's electronic. Article 25(2) goes further and gives QES the same standing as a handwritten signature.
| eIDAS level | What it means | Common use |
|---|---|---|
| SES | Broad electronic signature, including typed names or drawn marks | Routine approvals, many private contracts |
| AES | Uniquely linked to and capable of identifying the signer, with change detection | Higher-evidence business documents |
| QES | AES made with a qualified device and qualified certificate | Formal EU filings or high-assurance documents |
PDFYay is built for fast browser-based PDF signing, not for issuing EU qualified certificates. When I use it, the PDF opens locally. I click Add Signature, draw or type the signature, place it on the page, and download the signed file. Nothing gets uploaded.
What is a simple electronic signature in the EU?
A simple electronic signature in the EU is electronic data attached to or logically associated with other electronic data and used by the signer to sign. Under eIDAS Article 25, an SES cannot be denied legal effect or admissibility solely because it is electronic or because it is not a qualified electronic signature.
Examples include a typed name, a scanned signature image, a checkbox confirmation, an email sign-off, or a drawn signature on a PDF. The real question is usually evidence. Can you show who signed, what they signed, and that they meant to sign?
For a deeper explanation, see our guide to what a simple electronic signature is. In PDFYay, the simplest workflow is opening the editor, choosing Select PDF, placing text or a signature, then pressing Download. The screen never asks for an account or upload permission.
What is eIDAS 2.0 and the EU Digital Identity Wallet?
eIDAS 2.0 is the EU update that adds European Digital Identity Wallets to the existing trust services framework. Regulation (EU) 2024/1183 amends Regulation (EU) No 910/2014 and is designed to let EU users identify themselves, share verified attributes, and access trust services across member states.
The EU Digital Identity Wallet is meant to support identity verification and attribute sharing, not just signatures. It could shape future signing flows, where a person proves who they are before applying an electronic signature or requesting a qualified trust service.
Our explainer on eIDAS 2.0 and the EU Digital Identity Wallet covers timing, trust services, and what ordinary PDF signers should watch for. For now, most everyday documents still rely on SES or platform-based signatures unless a receiving party demands QES.
Are electronic signatures legal in the UK?
Electronic signatures are legal in the UK when the signer intends to authenticate the document and the document’s formal requirements are satisfied. The UK Electronic Communications Act 2000, retained eIDAS framework, and the Law Commission’s 2019 report on electronic execution support the general validity of e-signatures in England and Wales.
UK practice still varies by document. Deeds, witnesses, land transactions, corporate execution, and filings with particular agencies can demand extra steps beyond dropping a signature image onto a PDF.
For more practical detail, read are electronic signatures legal in the UK. When I prepare a simple UK PDF in PDFYay, the preview shows page thumbnails on the side and the active page in the center. The draggable fields stay exactly where I drop them before I download.
Are electronic signatures legal in Canada?
Electronic signatures are generally legal in Canada, but the exact rule depends on federal, provincial, or territorial law. Canada’s federal Personal Information Protection and Electronic Documents Act recognizes electronic signatures for many purposes, while provinces and territories have electronic commerce statutes with exceptions for certain wills, trusts, powers, and land-related documents.
Ontario’s Electronic Commerce Act, 2000 is one example of a provincial law that backs e-signatures while excluding certain document categories. Other provinces use similar but not identical frameworks, so the receiving organization’s rules matter.
A routine business PDF is usually fine for an electronic signature. A court filing, real-estate transfer, estate document, or government form may need a prescribed method, an identity process, or a wet-ink original.
Are electronic signatures legal in Australia?
Electronic signatures are generally legal in Australia under the Electronic Transactions Act 1999 and corresponding state and territory laws. A valid e-signature commonly depends on consent, reliable identification of the signer, and a method appropriate for the purpose, while certain witnessing, company execution, or excluded documents can require special handling.
The federal Electronic Transactions Act 1999 says a signature requirement can be met electronically if the method identifies the person and indicates intention, among other conditions. State and territory laws may govern particular documents, especially where witnessing or physical presence comes into play.
For everyday PDFs, a browser-based signer is usually enough if the recipient accepts it. In PDFYay, after I click Download, the saved file includes the visible signature and any text boxes I added. There's no “sent for signing” email and no cloud copy.
What is the difference between a digital and electronic signature in India?
The difference between a digital and electronic signature in India is that “electronic signature” is the broader legal category, while “digital signature” is a specific cryptographic method. India’s Information Technology Act, 2000 recognizes electronic signatures, and digital signatures use an asymmetric crypto system and hash function under that framework.
In everyday speech, people throw around “digital signature” to mean any online signature. In Indian legal and compliance contexts, a Digital Signature Certificate issued through the licensed Certifying Authority system is much more specific.
That distinction matters for government portals, tax filings, company filings, procurement, and regulated workflows. A visible signature dropped on a PDF can work for informal approval, but it isn't the same thing as a statutory DSC-based digital signature.
Is a US electronic signature valid in the EU?
A US electronic signature can be valid in the EU, but it is not automatically treated as an EU qualified electronic signature. The EU looks at the applicable law, the document type, intent, identity evidence, integrity evidence, and any required form. ESIGN and UETA do not convert a US signature into a QES.
The US ESIGN Act, 15 U.S.C. § 7001, says a signature or contract may not be denied legal effect solely because it is electronic. UETA provides a similar state-law model adopted in most US jurisdictions, but EU eIDAS has its own categories.
Cross-border private contracts often add governing-law, consent, and signature clauses to cut down on uncertainty. For a plain-language comparison, see ESIGN vs eIDAS.
When do I need a qualified electronic signature (QES)?
You need a qualified electronic signature when a law, regulator, public authority, court, or receiving party requires the highest eIDAS signature level. A QES has the legal effect of a handwritten signature under eIDAS Article 25(2), but it must be created using qualified trust-service infrastructure, not just a visible mark on a PDF.
Common QES scenarios include high-assurance EU public services, regulated professional filings, certain cross-border formalities, or documents where a rejection would be costly. Some organizations also require QES by policy even when the law would allow a lower signature level.
Use this quick risk checklist before choosing a signing method:
- Identify the country law and governing-law clause.
- Check whether the document category has formal signing rules.
- Ask the recipient which signature level they will accept.
- Confirm whether identity verification or certificate evidence is required.
- Preserve the final PDF, audit evidence, emails, and consent records.
- Use QES when a public authority or statute specifically requires it.
Is a typed name a valid signature in the EU?
A typed name can be a valid signature in the EU if it is used with intent to sign and is logically associated with the document. Under eIDAS, a simple electronic signature cannot be rejected solely because it is electronic, but typed-name signatures still depend on evidence, context, and any special legal formality.
A typed name works best when the surrounding record shows consent and intent. Useful evidence includes the final PDF, the email trail, IP or access logs from a signing system, contract language accepting electronic signatures, and proof that the signer controlled the communication channel.
To sign a routine PDF with a typed name in PDFYay:
- Open PDFYay’s free PDF editor.
- Click Select PDF and choose the file from your device.
- Click Add Text and type the signer’s name.
- Drag the text box to the signature line.
- Adjust the size so it fits the document.
- Add the date or initials if the form asks for them.
- Click Download to save the signed PDF locally.
The file stays in the browser the whole time. That privacy detail matters for contracts, HR forms, and IDs, because PDFYay doesn't require signup and never uploads the PDF to a server.
