You can transfer your domain in Squarespace by following these steps:

1. Log in to your Squarespace account.

2. Click on the "Settings" button on the left-hand sidebar of the dashboard.

3. Select "Domains" from the menu.

4. Click on the domain name that you want to transfer.

5. Click on the "Transfer Domain Away from Squarespace" link at the bottom of the page.

6. Follow the prompts to initiate the transfer and obtain the authorization code.

7. Once you have the authorization code, provide it to your new registrar to complete the transfer.

It's important to note that Squarespace requires a 60-day waiting period after the initial domain registration or transfer before it can be transferred to another registrar. Additionally, back up any DNS settings or custom email accounts associated with your domain before initiating the transfer, as these may be lost during the transfer process.
