Estate planning is the process of accumulating and disposing of an estate to maximize the goals of the estate owner. The various goals of estate planning include making sure the greatest amount of the estate passes to the estate owner's intended beneficiaries, often including paying the least amount of taxes and avoiding or minimizing probate court involvement. Additional goals typically include providing for and designating guardians for minor children and planning for incapacity.

The tools involved in estate planning include the will, various types of trusts, beneficiary designations, powers of appointment, various forms of property ownership (Joint tenancy with rights of survivorship, tenancy in common, tenancy by the entirety, etc), gifting, and powers of attorney, specifically the durable financial power of attorney and the durable medical power of attorney. After widespread litigation and media coverage surrounding the Terri Schiavo case, virtually all estate planning attorneys now advise their clients to also create a living will. Note that many people (and even some attorneys) confuse a living will with a durable medical power of attorney. The former controls solely those decisions that must be made at the end of the patient's life, while the latter is used to give decision-making authority to someone else (usually a family member or close friend). This person, the attorney-in-fact, then makes all medical decisions leading up to the person's death, but has no such power to make end of life decisions for the patient. Those decisions are made by the patient in the living will; in the absence of a living will, and where the patient is incapable of making end-of-life decisions for him or herself, such choices are left to family members.
