Banks are required under money laundering legislation to identify the beneficial owner who ultimately owns the company.
If a shareholder is a legal entity – banks will require additional due dilligence information, ie. certificate of incorporation and articles of incorporation (company from any jurisdiction) – if any jurisdiction other than the US and UK. We will need an English translation of the documents notarised and apostilled. (US and UK will need to be apostilled too but without the translation obviously…)
