Is an electronic signature legally binding?
Short answer:For most everyday agreements, yes. In the United States the ESIGN Act and the Uniform Electronic Transactions Act give electronic signatures the same standing as ink for most contracts, and the EU’s eIDAS regulation does the same across Europe. The exceptions are specific documents such as wills, some property transfers, and certain family and court papers, where the law insists on a particular method or traditional ink. If you are unsure whether a document is one of them, ask whoever sent it rather than guess.
What makes a signature valid
Electronic signature law generally asks for three things: that the signer intended to sign, that the signature is attached to the document, and that the record can be kept and reproduced. A signature you add on screen and save into the PDF meets those conditions. It is placed deliberately, it travels with the file, and the file can be stored and reopened.
Notice what is not required: a scan of ink, a printed copy, or special software. The paper ritual is convention, not law, for most agreements.
Electronic signature versus digital signature
The two sound alike and mean different things. An electronic signature is the broad category: any mark or process a person uses to sign electronically, including a drawn or typed name on a PDF. A digital signature is a specific technical method using cryptography to prove who signed and that the document has not changed since.
A digital signature gives stronger guarantees, and some regulated documents require one. For an everyday contract, an ordinary electronic signature is normally enough.
The exceptions
Wills and testamentary documents are the classic exclusion. So are certain property transactions, some family-law documents, and specific court or government filings. In the EU, qualified electronic signatures carry a special legal weight that ordinary ones do not, for documents where the law demands it.
That is why the honest answer to “is it binding?” depends on the document, not the tool. For anything routine, an on-screen signature is fine; for anything weighty, check what the other side requires.
More questions
Is an electronic signature legally binding?
For most everyday agreements, yes. The US ESIGN Act and Uniform Electronic Transactions Act and the EU’s eIDAS regulation give electronic signatures the same effect as ink for most contracts. Wills, some property transfers, certain family and court documents are exceptions. If you are unsure, ask whoever sent the document.
Do I need a scan of my signature to sign electronically?
No. A signature you draw, type or place on screen and save into the PDF is an electronic signature. A scan of ink is not required for most agreements; the paper ritual is convention rather than law.
What is the difference between an electronic and a digital signature?
An electronic signature is the broad idea: any electronic mark or process used to sign, including a drawn or typed name. A digital signature is a specific cryptographic method that proves who signed and that the file has not changed since. Digital signatures are stronger, and some regulated documents require them.
Are e-signatures valid outside the US and EU?
Most countries have adopted laws recognising electronic signatures, following frameworks such as the UN’s model law on electronic signatures. The details and any exceptions vary by country and document type, so for a specific legal matter it is worth checking local requirements.
