My Mam has Alzheimers. My Dad is still of sound mind. We were bit anxious about things in regard God forbid anything happened my Dad and none of us had Power of Attorney (we had also left it too late) so we went to see my Mam and Dad solicitor. The only real asset is the family home which has been willed a long time ago by Mam and Dad.
Solicitor told us that should anything happen to Dad, it would only be a matter of filing papers with the court and 2 doctors letters regarding my Mam's Alzheimers.
Very straight forward, this guy has been my Mam and Dad's rock for many a year and also a very highly regarded man in the Law Society and we trust him completely.
Dunno is this helps any bit, hope so
