Estate Planning

Jurisdiction: General U.S. overview (state law governs validity) State rules vary

Quick answer

Estate planning is the process of arranging, while you are able, for who will make decisions and manage property if you become incapacitated, and who receives what after you die. The core documents are a will, a durable power of attorney, a health care proxy or advance directive, and often a trust — and the formalities that make each one valid vary by state.

Estate planning is not only for wealthy people. If you own any property, have bank accounts, or want a say in your medical care, you have an estate to plan. Dying without a will does not avoid the legal process — it hands the decisions to state intestacy law and a court. These pages explain concepts in plain English; they are general information, not legal advice about your situation.

In detail

The core documents, in plain English

A will says who receives your property after death and names an executor to carry out the instructions. A durable power of attorney names someone to handle financial matters if you become unable to. A health care proxy (also called a health care power of attorney) names someone to make medical decisions for you, and a living will or advance directive states your wishes about life-sustaining treatment.

A trust is a separate legal arrangement that holds property for beneficiaries according to your instructions. Revocable living trusts are commonly used to avoid probate; other trusts serve purposes like tax planning, providing for a spouse, or protecting assets for a person with disabilities.

Why documents must be valid where you live

A will that is perfectly valid in one state may fail in another if it does not meet that state's witnessing or signature requirements. Powers of attorney are especially state-sensitive: some financial institutions resist out-of-state documents. If you move, have your documents reviewed under the new state's law.

Handwritten or online forms can work in some states and fail in others. The cost of a review by a licensed attorney in your state is small compared with the cost of a document that does not work when it is needed.

Keeping the plan current

Review your documents after major life events: marriage, divorce, the birth of grandchildren, a move to another state, a serious diagnosis, or the death of someone named in your documents. Also review beneficiary designations on retirement accounts and life insurance — those pass outside the will and override it.

Store originals where your executor or agent can find them, and tell them where they are. A perfect will locked in a safe nobody can open helps no one.

How this varies by state

Estate planning validity is state law. Common variations include:

  • Will formalities: number of witnesses, notarization, and whether handwritten (holographic) wills count.
  • Power of attorney forms: some states have statutory forms; acceptance by banks varies.
  • Advance directive terminology and default rules when no document exists.
  • Probate thresholds and simplified procedures for small estates.
  • Estate and inheritance taxes: most states have none, but a few do.

Estate planning documents are creatures of state law. The concepts below are general; the formalities that make a document valid — witnesses, notarization, signatures — differ by state.

Who may need help with this

  • Adults creating their first will or updating an old one
  • Couples coordinating wills, trusts, and beneficiary designations
  • People with property in more than one state
  • Parents or grandparents planning for a child or grandchild with disabilities
  • Anyone named as an executor, trustee, or power-of-attorney agent

Estate planning checklist

  1. Inventory what you own and owe: accounts, property, insurance, debts.
  2. Decide who you trust as executor, financial agent, and health care proxy — and ask them first.
  3. Put the core documents in place: will, durable power of attorney, health care proxy, living will.
  4. Check beneficiary designations on retirement accounts and life insurance; they override your will.
  5. Decide whether a trust fits your situation; get advice before retitling property.
  6. Store documents accessibly, tell your agents where they are, and review after major life events.

Common mistakes

  • Using a will from another state without checking local formalities.
  • Forgetting that beneficiary designations override the will.
  • Naming an executor or agent without telling them or confirming willingness.
  • Putting a child's name on accounts or deeds as a 'simple' alternative to a will — this can create tax and Medicaid problems.
  • Never reviewing documents after divorce, remarriage, or a move.

Questions to ask

  • Which documents do I actually need for my situation?
  • Is a trust worthwhile for me, or is a will enough?
  • How do you charge for an estate plan, and what does it include?
  • How will my plan work if I move to another state?
  • How often should I review these documents?

Frequently Asked Questions

Do I need a trust, or is a will enough?
For many people, a will plus powers of attorney and advance directives is enough. A revocable living trust mainly helps avoid probate and can simplify management if you become incapacitated — but it only works for property actually transferred into it. An attorney in your state can advise whether the benefits justify the cost in your situation.
What happens if I die without a will?
State intestacy law decides who receives your property, and a court appoints someone to administer the estate. The result may not match your wishes — for example, unmarried partners generally inherit nothing under intestacy law. A will lets you choose.
Can I write my own will?
In many states, yes — handwritten or fill-in wills can be valid if they meet the state's formalities. But mistakes are common and only surface after death, when they cannot be fixed. Having a licensed attorney review even a self-written will is usually worthwhile.
