My father wants me to have lasting power of attorney. He was diagnosed with Alzheimer's a few years ago and is on medication that appears to be effective. However, I am subject to an IVA which will be complete in March 2015. My father has no property, is in receipt of Pension credit and attendance allowance and there are no assets. My father resides with myself and my husband in our home. Can he still have me named for power of attorney?
