My significant other will take care of our children. Shouldn’t I just leave everything to him/her?

With estate planning, you must consider the various scenarios that may happen after your death and the impact on your planning goals. What if your significant other marries?

Sometimes it makes sense to leave everything to your significant other outright and free of any restrictions, and other times a more nuanced approach is required.
