Because there is a wide variety of retirement plans, such as 401(k) plans, IRAs, state and county retirement plans, pension plans, etc., many high net worth couples have several different types of plans.

Stock options come in many forms, and the attorneys chosen by each spouse must have experience and knowledge about all of the different nuances of each of the different assets.
