Business planning is a natural and integral addition to an estate planning practice.  Adding the formation of business entities such as limited liability companies and corporations to your existing estate planning practice will add value and flexibility to your estate plans for many clients who either are sole proprietors, own investment properties, or own family cabins that they wish to transfer to future generations.  Use of business entities can be useful planning tools because they can allow for more flexibility than a trust, in some situations, while having the added benefit of creditor protection. Likewise, a working understanding of business law, limited liabilities, and corporate law is necessary for estate planners to properly advise clients, who own (or should own) these types of interests, on how to incorporate these interests into their estate plan.
