Hello R6clj,
Thank you for reaching out in Apple Support Communities. Only the original owner of the iPad can remove their Apple ID account. If they do not remember the Apple ID password, they can attempt to reset the forgotten password or go through the account recovery process. Here's two articles with additional details and the proper steps to take:
If you forgot your Apple ID password
Here's how to reset your Apple ID password and regain access to your account.
The fastest and easiest way to reset your password is with your iPhone or other trusted Apple device — one that you're already signed in to with your Apple ID, so that we know that it's yours.
You need a passcode (or password on Mac) set up on your device.
Reset your Apple ID password on your iPhone or other trusted Apple device
1. Go to Settings.
2. Tap your name > Password & Security > Change Password.
3. Follow the onscreen instructions to reset your password.
You can also follow this process on a trusted iPad, iPod touch, or Apple Watch.
To reset your password on your trusted Mac, choose Apple menu  > System Settings (or System Preferences) > Sign in with your Apple ID (or Apple ID). Then click Password & Security, Change Password, and follow the onscreen instructions.
If you have a new Apple device
If you have a new Apple device or an Apple device that you aren't signed in to with your Apple ID, you can select "Forgot Apple ID or password?" wherever the option appears.
During device setup, you can find the "Forgot Apple ID or password?" option on the Apple ID sign-in screen. After setup, you can select an app or other option that prompts you to sign in:
* iPhone, iPad, or iPod touch: Go to the Settings app and tap Messages.
* Mac: Choose Apple menu  > System Settings (or System Preferences). Then click Sign in with your Apple ID (or Apple ID) and enter your Apple ID.
Reset your Apple ID password with the Apple Support app on a borrowed device
If you don't have an Apple device but have access to your trusted phone number, you can borrow an Apple device from a friend or family member, or use one at an Apple Store.
1. Open the Apple Support app on the borrowed Apple device. If needed, you can download the Apple Support app from the App Store.
2. Scroll down to Support Tools, then tap Reset Password.
3. Tap "A different Apple ID."
4. Enter your Apple ID, tap Next, and follow the onscreen instructions to reset your password.
Any information that you enter will not be stored on the device.
Reset your Apple ID password on the web
If you don't have a trusted device, you can reset your password on the web — but the process might take a little longer.
When possible, the web process redirects you to a trusted device. If you'll have access to one of your trusted devices soon, it might be faster and easier to reset your password then.
