Do you mean activation lock ? If you do, what happens when you tap in the id and password of the account that it's locked to ? If you can't remember your id have you tried : If you forgot your Apple ID - Apple Support ?
Or, and if you were the original purchaser of the iPad (i.e. it wasn’t bought used), you could try going to an Apple Store (make a Genius Bar appointment if you do) or try contacting iTunes Support online (https://www.apple.com/emea/support/itunes/contact.html) and see if they can remove the iPad from the account - they are likely to want to see proof of ownership before they might help e.g. original receipt with the serial number on it
