Overseas Subscriber Attestation explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
Where the person lives decides how many layers of authentication the document needs — one, two, or three.
The rule
The attestation requirements depend on the country in which registered office / residence of the overseas subscriber / director is situated. The documents are required to be attested as follows:
- Residing in a country which is part of the Common Wealth, by a notary public of that country;
- Residing in a country which is party to the Hague Apostille Convention, 1961, attested by a notary public and duly apostilled in accordance with the said Hague Convention; and
- Residing in a country which is not party to said Hague Convention, authenticated by a Diplomatic or Consular Officer empowered in this behalf under Section 3 of the Diplomatic and Consular Officers (Oaths and Fees) Act, 1948 i.e. attested by Public Notary and authenticated by Indian Embassy in the country of residence.
The tiers reflect how much India already trusts the certifying authority in that country, and each adds a layer where the previous assurance is unavailable.
Commonwealth countries — one layer. A notary public of that country suffices. Commonwealth legal systems share a common origin, and notarial acts from them are accepted directly.
Hague Convention countries — two layers. A notary attests, and the document is then duly apostilled. The apostille is the Convention's mechanism: a designated authority in the country certifies that the notary is genuine, so the receiving country need not verify the notary itself.
Everywhere else — three layers. A Public Notary attests, and then the Indian Embassy in the country of residence authenticates. With no treaty framework, India verifies the document through its own diplomatic officer, empowered under section 3 of the Diplomatic and Consular Officers (Oaths and Fees) Act, 1948.
The practical consequence is lead time. A Commonwealth attestation can be arranged in days; an apostille takes longer, depending on the designated authority; embassy authentication is the slowest and depends on appointment availability at a particular mission.
So the first question on any incorporation with an overseas subscriber is not what documents are needed but where the subscriber lives — because that determines whether the timetable is measured in days or weeks.
And the process consequence: because the attestation is physical, the electronic memorandum and articles give way. The incorporation is filed along with the manually signed and duly attested MOA and AOA.
The three routes
| Country | Attestation | Layers |
|---|---|---|
| Commonwealth | Notary public of that country | One |
| Hague Apostille Convention, 1961 | Notary public, then apostille | Two |
| Neither | Public notary, then Indian Embassy authentication | Three |
Who the requirement applies to
Note that the rule covers both the overseas subscriber and the overseas director, and refers to the registered office or residence. A corporate subscriber incorporated abroad is assessed on where its registered office is; an individual on where they reside.
The rule 13 requirement is specific about what is witnessed: the foreign national's signatures and address etc. — identity and address both, not merely the fact of signing.
Planning the incorporation
- Establish each overseas participant's country of residence at the outset.
- Determine which of the three categories it falls in.
- Build the attestation lead time into the incorporation timetable.
- Prepare for manually signed memorandum and articles where attestation is physical.
- Check that the reserved name will not lapse while attestation is pending.
Common mistakes
- Assuming a notary's attestation alone suffices outside the Commonwealth.
- Obtaining an apostille from a country that is not a Convention party.
- Beginning the overseas subscriber attestation after the name has been reserved.
- Attempting to file electronic memorandum and articles where physical attestation is required.
