Many years ago, I read a story about a family who was in a car wreck while on vacation in another state. The parents were killed, but all of the children survived and since the parents did not have an estate plan, the kids were put through a long, traumatizing court process. They were in foster care for 18 months before the guardian was appointed and could take them home. It was up to the state to approve medical treatments for the kids. Thousands of dollars were spent on legal fees. The youngest child had been 18 months old at the time of the car wreck, and he was three years old when he finally went home with the guardian.
The case really shook me, especially because at the time, my youngest was only two years old, and imagining that scenario was terrifying. It had a huge impact on the way I did planning for my clients. I have always started from facing the worst possible scenarios that could happen, and then planning to avoid any bad legal outcome that we could identify.
