# GetBucketOwnershipControls
<a name="API_GetBucketOwnershipControls"></a>

**Note**  
This operation is not supported for directory buckets.

Retrieves `OwnershipControls` for an Amazon S3 bucket. To use this operation, you must have the `s3:GetBucketOwnershipControls` permission. For more information about Amazon S3 permissions, see [Specifying permissions in a policy](https://docs.aws.amazon.com/AmazonS3/latest/userguide/using-with-s3-actions.html). 

**Note**  
A bucket doesn't have `OwnershipControls` settings in the following cases:  
The bucket was created before the `BucketOwnerEnforced` ownership setting was introduced and you've never explicitly applied this value
You've manually deleted the bucket ownership control value using the `DeleteBucketOwnershipControls` API operation.
By default, Amazon S3 sets `OwnershipControls` for all newly created buckets.

For information about Amazon S3 Object Ownership, see [Using Object Ownership](https://docs.aws.amazon.com/AmazonS3/latest/userguide/about-object-ownership.html). 

The following operations are related to `GetBucketOwnershipControls`:
+  [PutBucketOwnershipControls](API_PutBucketOwnershipControls.md) 
+  [DeleteBucketOwnershipControls](API_DeleteBucketOwnershipControls.md) 

**Important**  
You must URL encode any signed header values that contain spaces. For example, if your header value is `my file.txt`, containing two spaces after `my`, you must URL encode this value to `my%20%20file.txt`.
