Legality and records
Are electronic signatures legally binding?
In most of the world, yes. The US ESIGN Act and UETA, the EU's eIDAS regulation, and comparable laws elsewhere give an electronic signature the same standing as ink for most agreements. What is actually argued in a dispute is almost never whether electronic signatures count - it is whether this particular person signed this particular document, and what proves it.
What the law generally requires
The common thread across ESIGN, UETA and eIDAS is intent and attribution: the signer meant to sign, the signature is connected to the record, and the record can be retained and reproduced by whoever needs it later.
None of those is about the picture of a signature. A typed name, a drawn squiggle and a cryptographic certificate are all capable of satisfying them, and all capable of failing to.
The exceptions that catch people out
Most jurisdictions carve out a short list: wills and testamentary trusts, some family-law documents, certain court filings, and notices like eviction or utility termination. Some property transfers and anything requiring notarization have their own rules.
If a document is going to a court or a registry, check what that body accepts before choosing a tool. This is general information and not legal advice; a lawyer in the relevant jurisdiction is the only answer to a specific document.
What makes a signature hard to dispute
Evidence, gathered at the time. Who was sent the document and at which address, that they proved control of that address, when they opened it, when they submitted, from which IP, and exactly which version of the document they saw.
SignaCore records all of that: delivery to a named address, a one-time code the signer must pass before the document is shown at all, timestamps, IP, and a completed PDF made from that signer's own answers. Enforceability still depends on the document, the parties and the applicable law - but the evidence is the part a tool can actually provide.
