E-signature legality in Ireland
Éire
Ireland recognises e-signatures under eIDAS and the Electronic Commerce Act 2000.
The law in plain language
Ireland's Electronic Commerce Act 2000 established the legal foundation for e-signatures pre-eIDAS; the European Union (eIDAS) Regulations 2018 (S.I. No. 233/2018) implement the EU framework. Electronic signatures are admissible in Irish courts.
- Primary framework
- eIDAS + Electronic Commerce Act 2000 + European Union (eIDAS) Regulations 2018
- National act
- European Union (eIDAS) Regulations 2018 (S.I. No. 233 of 2018)
Signature tiers recognised in {country}
Ireland recognises the three eIDAS-aligned tiers. The right tier depends on the contract — most B2B documents are fine with SES; AES adds an identity-binding factor; QES carries the legal force of a handwritten signature for documents that require written form.
The baseline — admissible as evidence in court. Suitable for everyday commercial contracts.
SES + a second factor (typically SMS) that uniquely binds the signature to the signer.
AES + a qualified certificate from a Qualified Trust Service Provider. Equivalent to a wet signature.
Routinely signed electronically
- B2B service agreements, SaaS contracts, supplier MSAs
- NDAs, sales orders, partner agreements
- Employment offer letters, onboarding paperwork
- Independent contractor + freelance engagement letters
- Quotes, invoices, statements of work
- Internal HR documents (policy acknowledgements, training)
Still need wet ink
- Real estate transfers and mortgages (notarisation required)
- Wills, testaments, and inheritance documents
- Marriage, divorce, adoption and other family law instruments
- Some employment-termination documents under national labour law
- Land transfers requiring a deed (Property Registration Authority requires wet-signed deeds for the Land Registry)
