Certification should match the evidence required
A certified copy attests to a document in the manner provided by its issuing authority; it does not necessarily certify that every underlying statement is commercially accurate. Identify the exact filing or extract needed and ask the recipient whether electronic certification, a paper original or further authentication is required. This avoids ordering an unsuitable document merely because it bears a stamp.
Separate the registrar’s service from legalisation
Companies House explains how to obtain its certified documents, while the UK legalisation service covers a later authentication step where applicable. HCCH lists the international apostille framework and competent-authority information. Keep these services distinct in your request, since a company extract, a certified copy and an apostille perform different functions and may involve separate procedures.
