Immigration Advice Authority (IAA)
Find a regulated immigration adviser anywhere in the UK
The official regulator of immigration advisers (formerly the OISC). Use its adviser finder to locate a regulated adviser near you, or to check that an adviser is genuinely registered — unregulated immigration advice is a criminal offence and a real danger.

Independent Monitoring Authority (IMA)
The watchdog for Withdrawal Agreement rights against UK public bodies
If a UK public body — the Home Office, a council, the DWP, an NHS service — has failed to respect your Withdrawal Agreement rights, complain to the IMA. It doesn't resolve individual cases, but complaints power its inquiries and legal action (it has already beaten the Home Office in the High Court), so complain to the body itself as well.

Help at EU level
The Withdrawal Agreement is a two-sided treaty, monitored on both sides. In the UK, the monitor is the IMA (above). On the EU side, the European Commission monitors how EU countries implement the citizens' rights provisions — the mirror of the IMA's role here.
Petitions to the European Parliament
Raise a rights problem with your elected representatives in the EU
Every EU citizen — including EU citizens living in the UK — has a treaty right to petition the European Parliament on a matter within the EU's fields of activity that affects them directly. Petitions go to the Committee on Petitions, which has repeatedly examined how citizens' rights under the Withdrawal Agreement work in practice. No fee, no minimum signatures.

Complaints to the European Commission
Where the problem is on the EU side of the Withdrawal Agreement
If your problem concerns how an EU country is applying the Withdrawal Agreement — for example difficulties faced by your family members in an EU member state, or cross-border social security an EU country is handling wrongly — a complaint can be made to the European Commission under its standard procedure for breaches of EU law. For problems caused by UK institutions, the right monitor remains the IMA.
