My Dad is 82, diagnosed with Alzheimer's in May.My Dad and brother fell out with each other in 2020.My Dad started showing signs of cognitive decline last year. We (my Dad and I) were advised by GP then to sort out LPA. I had hoped that my Dad and brother would reconcile their differences as it was a minor issue that had been blown out of proportion, and their relationship had always been good. I thought that my brother could be sole attorney, as I am autistic and receive a package of support to manage my own affairs.My brother died suddenly in September last year. Social services became involved in May this year. We filled in the LPA forms (we did the whole paper version) and I submitted them several weeks ago on the social worker's advice (she knows my disability but said as I was the only person my Dad trusted, there was no other option). I haven't heard anything from the Office of the Public Guardian yet. My Dad has been going through his finances with me and he had been struggling more than he had let on. Not in any debt but just not managing his finances as usual (lease renewals on second properties etc). I am way out of my depth, social worker is not interested as my Dad will be self-funding any care. How do I do the best thing for my Dad? There are no other family or close friends. My Dad sees no need for a solicitor and says he just trusts me.How long will LPA take to be registered? Would it be morally wrong to then ask a solicitor to take over, as my Dad has considerable savings, two properties etc and I don't want to make mistakes? My Dad has capacity but is totally inflexible about trusting anyone but me. Please can anyone offer advice?
