My Dad has advanced dementia and is currently being cared for in an NHS facility. This placement is temporary and he will be moved to a nursing home upon his release. His wife has POA over his affairs and well being but I have had growing concerns that she is now demonstrating the onset of dementia and I don’t feel at all confident in her decision making about my fathers care. I would like to challenge her POA and wondered if someone could guide me on how to begin. We reside in Scotland so UK wide laws may not apply here so it would need to be specific to Scottish law I think. Thanks in advance for any help.
