The short answer
Yes. In the United States, electronic signatures have carried the same legal weight as handwritten signatures since 2000, when the ESIGN Act took effect federally. Nearly every state has also adopted UETA. Across the EU, the eIDAS Regulation does the same. A contract is not less enforceable simply because it was signed on a screen.
What actually makes a signature enforceable
Courts don't care about the pixels. They care about three things:
- Intent to sign. The signer must have meant to sign. A clear "I agree" button or a drawn signature establishes intent far better than an ambiguous checkbox buried in a footer.
- Consent to do business electronically. The signer must have agreed to use electronic records. For consumers, ESIGN requires this consent be obtained in a way that reasonably demonstrates they can access the electronic format.
- Attribution and integrity. You must be able to show who signed and that the document hasn't changed since. This is where the audit trail earns its keep.
Where e-signatures can fail
E-signatures are valid for the overwhelming majority of business documents, but a handful of categories still require wet ink or special handling in many jurisdictions:
- Wills, codicils, and testamentary trusts
- Certain family-law documents (adoption, divorce decrees)
- Some real-property transfers and notarized instruments
- Court orders and official court filings in some venues
The practical takeaway
Enforceability is rarely lost on the signature itself — it's lost on proof. When a signed agreement is challenged, the question is almost always "can you demonstrate intent, consent, and integrity?" A signing platform that captures a timestamped, tamper-evident audit trail answers all three before the dispute ever starts.
