Electronic signatures are now broadly valid for commercial contracts in the EU, UK and US, but legal effect, evidential weight and statutory form requirements are different questions. Some documents still need wet ink, a qualified electronic signature, notarisation or apostille and legalisation, and the Gulf requires attestation where an apostille is not available. Stamp duty on contracts is a live issue mainly in India.
Electronic signatures: valid, but not always sufficient
The EU eIDAS Regulation prevents an electronic signature being refused legal effect or admissibility just because it is electronic, and gives a qualified electronic signature the same effect as a handwritten one. The UK makes electronic signatures admissible as evidence of authenticity and integrity, and the US federal E-SIGN Act stops a contract in interstate or foreign commerce being denied effect solely because it was signed electronically.
Where a statute requires written form, a plain electronic signature may not be enough. In Germany, statutory written form can be replaced by electronic form only with the issuer's name and a qualified electronic signature, and documents such as GmbH articles of association need notarial form signed by all shareholders. Check the form rule for each document, not just the general validity rule.12345
Apostille, legalisation and attestation
Corporate documents, powers of attorney and judgments used abroad usually need certification. The Hague Apostille Convention replaces legalisation with a single apostille between contracting states; it is in force for India, Saudi Arabia (since 7 December 2022), Singapore (since 16 September 2021), the UK, the US, Germany and France. The UAE is not listed as a party, so documents for the UAE go through legalisation and attestation; for example, a foreign judgment to be enforced onshore must be attested by the UAE Ministry of Foreign Affairs.
Authority to sign is a separate formality. Under UAE onshore arbitration law, a company can agree to arbitration only through a representative authorised to conclude arbitration agreements, failing which the agreement is void. A board resolution or power of attorney expressly covering arbitration avoids this risk.6789
Stamp duty on contracts
In India stamp duty is mainly a state levy, so the rate on an agreement depends on the state, with the central government fixing rates for specified instruments. Unstamped or under-stamped instruments can cause problems when relied on in evidence; the rate and timing for each instrument and state should be confirmed before signing.10

Decisions to make
- Does any document in the deal have a statutory form requirement (written form, deed, notarisation)?45A general e-signature rule does not satisfy a specific form requirement such as German written or notarial form.
- Will the document be used in a country that is not an Apostille party?78The UAE is not a party, so legalisation and Ministry of Foreign Affairs attestation take longer than an apostille.
- Is the signatory authorised to agree arbitration on the company's behalf?9Under UAE onshore law an arbitration agreement signed without that authority is void.
- Is the contract executed or to be relied on in India?10Stamp duty depends on the state and the instrument.
Documents usually needed
- Signing authority: board resolution or power of attorney, expressly covering arbitration where relevant
- Qualified electronic signature certificates where German written form or EU qualified signatures are needed
- Apostille, or legalisation and attestation chain for the UAE, for corporate documents and powers of attorney
- Notarial deed for German corporate acts requiring notarial form
- Stamp duty payment evidence for Indian instruments
Common mistakes
- Assuming a click-to-sign platform satisfies every statutory form requirement
- Ordering an apostille for a document destined for the UAE
- Letting a manager without express arbitration authority sign a UAE contract with an arbitration clause
- Leaving Indian stamp duty until a dispute, when the instrument is needed in evidence
- Signing a power of attorney abroad without checking the receiving country's certification chain

The United Arab Emirates does not appear in the HCCH status table of the Apostille Convention, so documents for use in the UAE cannot be apostilled and go through legalisation and attestation instead.
