Lasting Powers of Attorney are only needed in later life
Mental capacity is not something you only lose through conditions such as dementia or purely due to old age. Losing mental capacity can happen at any age, whether that be from an accident or injury, certain mental health conditions, or from abuse of drugs/alcohol.
There is also a common misconception that someone’s ‘next of kin’ can make decisions on behalf of a person if that person is incapacitated and this is not the case.
