# Changing countries

CourtAid organises all research by **country**. When you switch country, you change which court database, legislation, and filters are available.

## Supported countries

| Country            | What's included                                                       |
| ------------------ | --------------------------------------------------------------------- |
| **Australia**      | Federal and state/territory courts, legislation, and the Constitution |
| **New Zealand**    | NZ courts, legislation, and legal categories                          |
| **United Kingdom** | UK, Scotland, and Northern Ireland courts and legislation             |
| **United States**  | Federal and state case law via CourtListener (restricted access)      |

{% hint style="warning" %}
**United States** is only available to authorised users. If you don't see it in your country list, contact support.
{% endhint %}

## How to change country

There are three ways to switch:

### 1. Sidebar (recommended)

At the bottom of the left sidebar, next to your name, click the **flag icon**. A searchable list of countries appears — select the one you need.

This is the quickest way to switch while navigating the app.

### 2. Filters panel

Open **Filters** (from the chat input bar or the Search page) and change the **Country** dropdown at the top of the panel.

This is useful when you want to change country and set other filters at the same time.

### 3. Automatic suggestion

If CourtAid detects that your browser timezone suggests a different country than the one you're currently using, a dialog will ask:

> **Switch country?** Stay on \[current country] · Switch to \[suggested country]

This only appears once per session. You can always change manually later.

## What happens when you switch

When you select a new country:

1. **The URL updates** — e.g. from `/au/chat` to `/uk/chat`
2. **You stay on the same page type** — if you were on Search, you'll still be on Search
3. **Filters reset to match the new country** — jurisdiction and court options change
4. **Your preference is saved** — if you're signed in, CourtAid remembers your default country

## Country-specific differences

Not every country has the same filters or document types:

| Feature              | AU          | NZ | UK | US |
| -------------------- | ----------- | -- | -- | -- |
| Document Type filter | ✅           | ✅  | ✅  | ✅  |
| Jurisdiction filter  | ✅           | ❌  | ✅  | ✅  |
| Court filter         | ✅           | ✅  | ✅  | ❌  |
| Categories filter    | ✅           | ✅  | ✅  | ❌  |
| Constitution         | ✅ (AU only) | ❌  | ❌  | ❌  |

### Australia

Full filter set including Federal and all states/territories, grouped courts, and legal categories.

### New Zealand

Document Type, Court, and Categories. No separate jurisdiction filter.

### United Kingdom

Jurisdiction covers UK, Scotland, and Northern Ireland. Courts and categories available.

### United States

Document Type shows **Case Law (Opinions)** and **Legislation**. Jurisdiction covers Federal and all 50 states plus DC. Court and Categories filters are not used.

## Tips

* **Set country before you start** — switching mid-research means re-running your query against a different database
* **Check the flag** — the flag icon in the chat input bar shows which country your current query will use
* **Multi-jurisdiction practices** — complete your research in one country, switch, and re-run. See [Common use cases](/getting-started/common-use-cases.md#7-cross-jurisdiction-comparison)

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.courtaid.ai/legal-research-and-search/changing-countries.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
