Your digital life after you die – how to protect your memories, money and identity

Why is estate planning so hard? And what you can do to make it easier…

Estate planning is one of those tasks almost everyone means to get to, yet many only face it during a crisis. Families often describe the same moment.

Am I doing the right things? The truth is, most of us make life more complicated than it needs to be.
