Dear Liz: You recently discussed the importance of adding spouses to financial accounts before one of them dies to make it easier for the surviving spouse. I wholeheartedly agree. I would add that this needs to be done sooner rather than later. If one of the spouses is diagnosed with dementia, the bank will likely not make changes to accounts. People have to be able to understand what they are signing.

Answer: That’s an excellent point. Another important task is to create powers of attorney for healthcare and finances. These allow someone else to make decisions for you if you are incapacitated. Someone in the early stages of dementia could sign such a document if they understand what it is, but otherwise the family might have to go to court to get a conservatorship, which can be an expensive process.
