Sources & standards

How we prepare our guides

Every published factual guide shows its sources, author, publication date and date of the last substantive check. Requirements in law will be distinguished from an organisation’s own practice. Drafts and unverified changes will stay unpublished.

Tax, residence, legal procedures and investment calculations will receive additional review. Published guides distinguish general preparation from rules that depend on your situation. No investment return is promised.

Official starting points

These directories help you find official information. Individual published guides link to the specific legislation and guidance used.
