We are now living longer than ever before. The likelihood of us losing capacity at some point, whether through dementia, illness or accident, is becoming an accepted part of life. It is often assumed that those closest to us will simply take over and make decisions about our finances and health care if we could no longer look after our affairs. However, suppose you are considered to have lost mental capacity. In that case, financial institutions, such as your bank, will usually freeze all your bank accounts, even if they’re joint accounts, and prevent any access to funds.
