I am having problems with a financial LPA who has sole attorneyship of my mother in law's money. She had an LPA set up before moving back into sheltered accommodation in her home town. Everything was fine at first, until I told the family member LPA that I was coming to visit. A tearful phone call about health issues followed, so I didn't go. Then contact became increasingly sporadic, I emailed and phoned, seldom a response. I then said I would be visiting again. An email to "request" I stayed away. I didn't and my shock at MIL's physical appearance - down 3 dress sizes in around 18 months - minimal carer attendance, disgusting frozen food. I put my concerns in writing to LPA - no response. I then applied for health and welfare deputyship, asked for an capacity assessment from MIL's GP. Firstly the surgery denied my contact, then refused to do the assessment. following advice from Court of Protection, sent the paperwork with explanations of attempts to obtain COP3 assessment - deputyship on hold because no assessment! Following these attempts and the "unauthorised" visit, received a letter written by MIL, but "copied" and not her words, banning me and anyone connected with me from visiting. A recorded phone call to MIL got the response it was "someone's idea." I have online access to one bank account, permission provided by LPA and not rescinded. Access shocked me, over £50,000 spent since October 2015, mostly NOT on MIL. Contacted OPG - blanked as they do not accept online statements! Have now contacted my and MIL's MPs, the local police where I live and where she lives. They will do a welfare check but seem to think that my findings - which would be obvious to anyone - do not constitue enough evidence for a fraud investigation. What now?
