i purchased a used ipad ini that has actixation lock can someone tekk me how to remove please

Here are the Apple support pages that outline the Activation Lock - and the only mechanisms by which it can be turned off:

Activation Lock for iPhone, iPad, and iPod touch - Apple Support

Turn off Activation Lock – Apple Support

As you will discover, unless you are the owner of the AppleID that was last used to activate the device, or unless you can secure the cooperation of the previous owner, you’ll not be able to defeat or bypass the Activation Lock. Without documentary evidence that you are the original owner (such as sales receipt showing the serial number), Apple won’t assist - and nobody here will be able to help you.

The All Too Common SAD Reality of Buying … - Apple Community

Without the needed info of the previous/original owner of that iPad, that iPad is a dead, useless device to you.

You purchased a paperweight.

Attempt to return this device and get your money back.

Failing that, please recycle this device responsibly.

You will never get this iPad to ever work for you.

Sorry & Best of Luck to You!
