An electronic signature has the same legal effect as a handwritten one in the Netherlands, provided the method used is sufficiently reliable in view of the purpose of the document and the circumstances. That is the rule in Article 3:15a of the Dutch Civil Code, and it is deliberately open: the law does not prescribe a technology, it asks whether the method fits the transaction.
The European eIDAS Regulation adds structure by distinguishing three types. A simple electronic signature is any electronic data attached to a document to sign it – a typed name, a scanned signature, a click. An advanced electronic signature is uniquely linked to the signatory, capable of identifying them, and detects any subsequent alteration of the document. A qualified electronic signature is an advanced signature created with a qualified device and based on a qualified certificate, and it has the same legal effect as a handwritten signature throughout the European Union by operation of law.
Which type do you need?
For most everyday commercial documents a simple or advanced signature is adequate, and in practice the advanced signature offered by the established signing platforms is the sensible default: it identifies the signatory and shows whether the document has been altered, which is what a dispute will turn on.
A scanned signature pasted into a document sits at the weak end. It proves very little: anyone with the file can reuse it, and it says nothing about whether the document was changed afterwards. It is not worthless, but if the signature is denied, the party relying on it carries the burden of showing that the method was reliable enough.
Where an electronic signature is not enough
Some acts require a notarial deed or a specific form, and an electronic signature cannot substitute for that: the transfer of registered property, the transfer of shares in a B.V., the incorporation of a company. Certain family law and employment documents also attract form requirements. Before signing anything electronically, the first question is whether the law imposes a form for that particular act.
Making an electronic signature hold up
What decides a dispute is evidence about the signing process rather than the signature image. Keep the audit trail the platform generates: who signed, when, from which address, how they were authenticated, and the hash showing the document is unchanged. Agree in advance, ideally in the contract itself, that the parties accept electronic signing and which method will be used. And match the method to the stakes: a qualified signature for a transaction worth defending, a simple one for a routine confirmation.
Frequently asked questions
Is an email confirmation a signature?
It can be a simple electronic signature where it is intended to sign. Whether it is sufficiently reliable depends on the document and the circumstances, and for anything significant it is a thin foundation.
Is a qualified signature necessary for contracts?
Rarely by law, but it removes the argument. A qualified signature has the effect of a handwritten signature by operation of law, so its reliability is not open to debate.
Can a party deny having signed electronically?
They can dispute it, which is why the audit trail matters. With an advanced or qualified signature, denial is difficult; with a pasted image, it is not.
