Hi walls14@btinternet.com
Firstly if the above is your personal email then please change your Forum user name for internet security reasons.
If you have a power of attorney it is common practice to take the LPA document to the Jobcentre where it is copied and stamped as a true copy and then forwarded to the relevant DWP department.
Hope this helps
