# Leave A Group
> Learn how to leave a group and receive real-time events when members leave using the CometChat React Native SDK.
```javascript theme={null}
// Leave a group
await CometChat.leaveGroup("GUID");
// Listen for member left events
CometChat.addGroupListener("listener", new CometChat.GroupListener({
onGroupMemberLeft: (message, leavingUser, group) => { }
}));
```
Leave a group to stop receiving messages and updates from it. Once you leave, you'll need to rejoin to participate again.
Group owners cannot leave without first transferring ownership to another member. See [Transfer Group Ownership](/sdk/react-native/transfer-group-ownership).
## Leave a Group
Use `leaveGroup()` to leave a group.
```typescript theme={null}
const GUID: string = "GUID";
CometChat.leaveGroup(GUID).then(
(hasLeft: boolean) => {
console.log("Group left successfully:", hasLeft);
}, (error: CometChat.CometChatException) => {
console.log("Group leaving failed with exception:", error);
}
);
```
```javascript theme={null}
const GUID = "GUID";
CometChat.leaveGroup(GUID).then(
hasLeft => {
console.log("Group left successfully:", hasLeft);
}, error => {
console.log("Group leaving failed with exception:", error);
}
);
```
| Parameter | Description |
| --------- | --------------------------------------------- |
| `GUID` | The GUID of the group you would like to leave |
Once a group is left, the user will no longer receive any updates or messages pertaining to the group.
On success, the method resolves with `true` (boolean).
## Real-time Group Member Left Events
Register a `GroupListener` to receive events when members leave.
```typescript theme={null}
CometChat.addGroupListener(
"UNIQUE_LISTENER_ID",
new CometChat.GroupListener({
onGroupMemberLeft: (message: CometChat.Action, leavingUser: CometChat.User, group: CometChat.Group) => {
console.log("User left", { message, leavingUser, group });
}
})
);
```
```javascript theme={null}
CometChat.addGroupListener(
"UNIQUE_LISTENER_ID",
new CometChat.GroupListener({
onGroupMemberLeft: (message, leavingUser, group) => {
console.log("User left", { message, leavingUser, group });
}
})
);
```
Always remove group listeners when they're no longer needed (e.g., on component unmount or page navigation). Failing to remove listeners can cause memory leaks and duplicate event handling.
```javascript theme={null}
CometChat.removeGroupListener("UNIQUE_LISTENER_ID");
```
## Missed Group Member Left Events
When fetching message history, leave events appear as [`Action`](/sdk/reference/messages#action) messages with:
* `action` — `"left"`
* `actionBy` — [`User`](/sdk/reference/entities#user) who left
* `actionFor` — [`Group`](/sdk/reference/entities#group) that was left
