UK Legal System Basics for Immigrants
The United Kingdom does not have a single legal system. It has three, and which one you are in changes the courts, the terminology and often the law itself. This guide sets out that split first, then the rights and sources of help that sit inside it.

In short
- There are three legal systems, not one: England and Wales, Scotland, and Northern Ireland.
- The Human Rights Act 1998 applies across the United Kingdom to everyone present, whatever their status.
- The Equality Act 2010 covers England, Scotland and Wales. Northern Ireland has its own separate equality laws.
- Legal aid is run separately in each of the three systems, with different rules in each.
- GOV.UK pages about courts, arrest and legal aid cover England and Wales unless they say otherwise.
The United Kingdom contains three separate legal systems: England and Wales, Scotland, and Northern Ireland. Courts, criminal procedure, legal aid, equality law and the professional bodies that regulate solicitors are all separate. The Human Rights Act 1998 applies across all three to everyone present, whatever their immigration status. This guide covers the basics and says, section by section, which nation each rule applies to.
Three Legal Systems, Not One
This is the thing most guides to "the UK legal system" get wrong. There is no such single system. The United Kingdom contains three:
- England and Wales — one jurisdiction shared by both nations, though the Senedd now makes some Welsh law of its own
- Scotland — a separate system with its own courts, its own prosecution service, and its own legal profession
- Northern Ireland — a separate system again, with its own courts and its own professional bodies
England and Wales and Northern Ireland are common law systems, built on statute and on decided cases. Scots law is a mixed system: it draws on Roman and continental civil law as well as on decided cases, and a good deal of its terminology has no English equivalent.
Immigration and nationality law is made for the whole United Kingdom, so the rules in the rest of Rowan apply wherever you live. Almost everything around them does not. GOV.UK pages on courts, arrest, legal aid and much else cover England and Wales unless they state otherwise, and normally link to the Scottish and Northern Ireland equivalents at the foot of the page.
Your Legal Rights
The Human Rights Act 1998 applies across the whole United Kingdom, to everyone present in it, whatever their immigration status. It brings the European Convention on Human Rights into domestic law, including:
- The right to life, and to liberty and security
- The right to a fair trial
- Freedom of thought, conscience and religion
- Freedom of expression
- Respect for private and family life
- Protection from discrimination in the enjoyment of those rights
Separately, discrimination law protects nine protected characteristics: age, disability, gender reassignment, marriage and civil partnership, pregnancy and maternity, race, religion or belief, sex, and sexual orientation. That list comes from the Equality Act 2010, which covers England, Scotland and Wales only. Northern Ireland is not in the Equality Act: it has its own set of anti-discrimination laws, overseen by the Equality Commission for Northern Ireland. See the GOV.UK discrimination rights page and our workplace discrimination guide.
Employment law and consumer law protect everyone working or buying in the United Kingdom, again regardless of status, though some employment rights are reserved to Great Britain and run differently in Northern Ireland.
The Courts
Because there are three systems there are three sets of courts. The names are not interchangeable.
England and Wales
- Magistrates' court: every criminal case starts here, and most finish here. Youth courts deal with defendants under 18
- Crown Court: the most serious criminal cases, tried before a judge and jury
- County Court: civil claims such as debt, housing and personal injury
- High Court and Court of Appeal: serious civil cases, and appeals
Scotland
- Justice of the peace courts: the least serious criminal cases
- Sheriff courts: most criminal and most civil business, including a simple procedure for smaller civil claims
- High Court of Justiciary: the most serious crime, and the final court of appeal for Scottish criminal cases — those do not go to the UK Supreme Court
- Court of Session: the senior civil court
Prosecutions in Scotland are brought by the Crown Office and Procurator Fiscal Service, not by the Crown Prosecution Service.
Northern Ireland
- Magistrates' courts and county courts for less serious criminal and for civil work
- Crown Court for serious crime
- High Court and Court of Appeal of Northern Ireland above them
Across the United Kingdom
- The Supreme Court: the final court of appeal for civil cases from all three systems, and for criminal cases from England and Wales and from Northern Ireland — but not from Scotland
- First-tier Tribunal (Immigration and Asylum Chamber) and the Upper Tribunal above it: immigration and asylum appeals, for the whole United Kingdom
- Employment tribunals: workplace disputes in England, Scotland and Wales. Northern Ireland has its own industrial tribunals and a separate Fair Employment Tribunal
GOV.UK describes the courts of England and Wales; the Scottish Courts and Tribunals Service and the Judiciary of Northern Ireland publish their own. For immigration processes, see our guides on visa appeals and judicial review.
Legal Aid and Free Legal Help
Legal aid is government-funded legal help for people who cannot afford to pay. It is not one scheme. England and Wales, Scotland and Northern Ireland each run their own, with their own eligibility rules, and each publishes its own guidance:
- England and Wales: GOV.UK legal aid, which includes a checker for whether your type of problem is covered
- Scotland: the Scottish Legal Aid Board
- Northern Ireland: the Legal Services Agency Northern Ireland, under the Department of Justice
For England and Wales, GOV.UK lists asylum, discrimination, family cases involving domestic abuse, child welfare, some housing cases and coroners' inquests among the areas covered, and says legal aid does not usually cover debt (unless your home is at risk), most employment disputes, or most benefits appeals. Whether you get it also depends on your income and savings.
Other sources of free help:
- Citizens Advice in England and Wales, Citizens Advice Scotland, and Advice NI in Northern Ireland: free confidential advice on housing, employment, debt and benefits
- Law centres and university law clinics, which exist in some areas and not others
- The duty solicitor at a police station, which is free to everyone regardless of income
For immigration advice specifically, it is a criminal offence to give it unless you are regulated. Check any adviser on the GOV.UK adviser finder, which covers advisers regulated by the Immigration Advice Authority as well as solicitors, barristers and legal executives regulated by their own professional bodies. Our immigration scams guide covers what unregulated advisers look like.
If You Are Arrested
The rules below are the ones GOV.UK publishes for England and Wales. The law on arrest is different in Scotland and different in Northern Ireland; mygov.scot and nidirect publish those.
GOV.UK says that when you arrive at a police station the custody officer must explain that you can:
- Get free legal advice
- Tell someone where you are
- Have medical help if you are feeling ill
- See the Codes of Practice — the rules the police must follow
- Be given a written notice setting out your rights, including regular breaks for food and to use the toilet
You can ask for that notice in your own language, or for an interpreter to explain it. If you are under 18 or vulnerable, the police must find an "appropriate adult" to protect your interests, rights and welfare. The full guidance is on GOV.UK.
Key Laws That Affect Daily Life
- Employment law: minimum wage, working time, holiday entitlement, protection from unfair dismissal — see our employment rights guide
- Housing law: tenancy protections, deposit rules and eviction procedure, all of which differ sharply between England, Wales, Scotland and Northern Ireland — see our renting guide
- Consumer law: refunds, product safety and fair trading, mostly United Kingdom-wide
- Equality law: the Equality Act 2010 in England, Scotland and Wales; separate legislation in Northern Ireland — see our discrimination guide
- Criminal law: assault, theft, driving, drugs and public order. Much is similar across the three systems, but the offences, the sentences and the procedure are not identical
The GOV.UK justice and the law section is the starting point for England and Wales.
If You Are a Victim of Crime
Call 999 in an emergency, or 101 to report a crime that is not an emergency. Anyone can report a crime, whatever their immigration status.
Support is organised nationally:
- Victim Support in England and Wales, Victim Support Scotland, and Victim Support NI in Northern Ireland — all free charities
- Compensation for a violent crime: the Criminal Injuries Compensation Authority scheme covers England, Wales and Scotland. Northern Ireland has a separate scheme run by the Department of Justice
See our emergency services guide.
Where to Start
The first question to settle is which of the three systems you are in, because that determines which courts, which legal aid scheme and which professional register apply to you. From there, Citizens Advice and its Scottish and Northern Ireland equivalents cover general problems, and the GOV.UK adviser finder covers immigration ones.

Questions and answers
Is there one legal system for the whole United Kingdom?
No. The United Kingdom contains three separate legal systems: England and Wales, Scotland, and Northern Ireland. They have different courts, different court names, different procedure, and in many areas different law. Immigration and nationality law is made for the whole United Kingdom, but almost everything around it — the courts you would use, legal aid, criminal procedure, equality law — depends on which of the three you are in. Where a guide or a GOV.UK page does not say which one it covers, it usually covers England and Wales.
Do immigrants have the same legal rights as British citizens?
The Human Rights Act 1998 applies across the United Kingdom to everyone in it, whatever their immigration status: the right to a fair trial, freedom of expression and religion, and respect for private and family life among others. Employment law and criminal law protect everyone in the same way. Some things are tied to status rather than presence: voting in a UK general election is limited to British, Irish and qualifying Commonwealth citizens, and a visa with a 'no public funds' condition blocks most benefits.
How do I find a solicitor in the UK?
Each of the three legal systems has its own professional body and its own public register: the Law Society of England and Wales, the Law Society of Scotland, and the Law Society of Northern Ireland. Each publishes a search of solicitors currently entitled to practise. For immigration matters specifically, use the GOV.UK adviser finder, which lists advisers regulated by the Immigration Advice Authority, and solicitors, barristers and legal executives regulated by their own professional regulators.
What is legal aid and can I get it?
Legal aid is government-funded legal help for people who cannot afford to pay. It is run separately in each of the three legal systems, with different rules in each. In England and Wales, GOV.UK says it covers matters including asylum, discrimination, family cases after domestic abuse, child welfare and housing, and that it does not usually cover debt (unless your home is at risk), most employment disputes, or most benefits appeals. Whether you get it depends on the type of case and on your income and savings. GOV.UK publishes a checker for England and Wales; Scotland and Northern Ireland have their own.
What are my rights if I am arrested in England or Wales?
GOV.UK says that when you arrive at a police station the custody officer must explain that you can get free legal advice, tell someone where you are, have medical help if you are feeling ill, see the Codes of Practice the police must follow, and be given a written notice setting out your rights. You can ask for that notice in your language, or for an interpreter to explain it. Anyone under 18 or vulnerable must have an 'appropriate adult' with them. The law on arrest is different in Scotland and different in Northern Ireland.
This guide is general information about published immigration rules. It is not advice about an individual application under s.82 Immigration and Asylum Act 1999, and Rowan is not regulated by the Immigration Advice Authority. Immigration rules change several times a year. For advice on a particular situation, contact an adviser authorised by the Immigration Advice Authority or an immigration solicitor. Always check GOV.UK for the authoritative current rules.
