I bought an apple ipad from a second hand store and it has activation lock on it is there any way to change it so i may use it

Activation Lock Problem

If you purchased the device second-hand, then it is useless without the Apple ID and password to which it is locked. If you don't have it, can't remember it or cannot get it, then the device is useless to you. Try to get your money refunded, if you can, or take it to an Apple store for an exchange provided they will help you. If you are the original owner, then take the device, a copy of your purchase receipt and identity proof to an Apple retailer where they may be able to assist you. For a deceased owner, you will need a certified copy of the Death Certificate, the device, proof of inheritance and proof of your identity. Take all to your local Apple Store for help. Note: there is no guarantee that anyone can gain access to the device.

You acquired your device second hand from someone other than Apple or an authorized Apple reseller. The information below explain what has happened. You apparently didn't know to heed the advice given below.

"Before you buy/acquire an iPhone, iPad, or iPod touch from someone other than Apple or an authorized Apple reseller, make sure that the device is erased and no longer linked to the previous owner’s account."

And see: Activation Lock for iPhone, iPad, and iPod touch https://support.apple.com/en-us/HT201365. See this heading Check for Activation Lock before you buy/acquire a device from someone else.

 What all this means is that there is no way we can help you. We are not authorized to remove the activation lock from any device. And, under your circumstances, Apple support will not help you since you cannot provide proof of ownership that they will consider to be sufficient. You would need and have your purchase receipt for the device from an authorized Apple seller with the device's serial number on it. 

All I can suggest is that you try to recovery the needed password (or possibly the purchase price) from the party you acquired the iPhone from. Recovering the password is the only way the phone can be made functional for your use. And getting it from the person you acquired it from is the only way to so.
