Let's say Dad passes away and leaves a half-million dollar estate to be divided equally among his three children. Trust us, you're going to need some professional guidance to make this happen in the smoothest possible manner. Even families that get along and communicate well end up having a difficult time with self-administration of a will. The first thing you should do is mutually agree on a trustee. It won't be cheap, but you can split the cost equally. The financial and personal risk of not hiring a trustee is much higher.
