The date of revocation was 22Jan
Is it not possible that she could have had capacity on the day she revoked the POA, and that she could have deteriorated in a short space of time so therefore failing the capacity assessment. on Tues.
We know alzheimers can often fluctuate. I don't see how her ability to make decisions 3 or 4 weeks ago would, in the eyes of the law, be necessarily the same as her ability today.
Surely there is a time limit, in the eyes of the law between the assessment and the signing of any legal document, e.g.date of assessment then signing for POA.
