Estate Planning Checklist: The Documents Every Adult Needs

What is estate planning, really?

Estate planning is simply deciding — in writing, while you're able — who makes decisions for you if you can't, who receives what you leave behind, and how. That's it. It has nothing to do with how much money you have. A modest home, a car, a checking account, a couple of retirement accounts, and people you love is already an estate. Without a plan, the state's default rules decide who's in charge and who gets what, often slowly and not the way you'd have chosen.

What documents do I need for estate planning?

Here are the core documents, roughly in the order they matter for most people. You don't have to do them all at once — but each one closes a gap that would otherwise fall on your family.

• A will. Names who inherits your things, who's in charge of carrying it out (your executor), and — if you have dependents — who cares for them. Without a will, state law decides all of this for you.
• A durable power of attorney for finances. Lets someone you trust pay your bills and manage money if you're unable to. “Durable” means it stays in effect if you become incapacitated — which is exactly when you need it most.
• A health care power of attorney. Names the person (your “health care proxy”) who can make medical decisions for you if you can't speak for yourself. Choose someone who knows your values and will honor them.
• An advance directive, or living will. Puts your wishes about life-sustaining treatment in writing, so your family isn't left guessing at the hardest possible moment.
• A HIPAA authorization. Gives your doctors permission to share your medical information with the people you name — without it, even close family can be shut out.
• Up-to-date beneficiary designations. Retirement accounts, life insurance, and payable-on-death bank accounts pass to whoever is named on the beneficiary form — not to whoever is named in your will. This is the single most-overlooked piece: an ex-spouse or a deceased relative left on an old form overrides everything else.

Beyond the documents: what your family will actually need

The documents decide who's in charge and who inherits. But the people stepping in also have to find everything — and that's where most families get stuck. A drawer full of unlabeled papers and a phone full of logins nobody can open turns a hard week into a months-long scavenger hunt.

• Every account and where it lives — banks, retirement, investments, pensions.
• Insurance policies — life, health, long-term care, home, auto.
• The estate documents themselves, and your attorney's contact information.
• Logins and passwords — or at least how to get into your phone and email, which unlock the rest.
• Recurring bills, subscriptions, and automatic payments to stop or continue.
• Key contacts — financial advisor, accountant, doctors, and the people to notify.

How often should I update my estate plan?

Review your plan every three to five years, and any time your life changes in a big way. Documents that were perfect a decade ago can quietly become wrong. Update after:

• A marriage, divorce, or remarriage — including your own and your beneficiaries'.
• A birth or death in the family.
• A move to another state, since estate laws differ from state to state.
• A significant change in your assets — selling a home, an inheritance, retiring.
• A change of heart about the people you named as executor, agent, or proxy.

Where should I keep my estate planning documents?

• In one place your family can actually reach. Be careful with bank safe-deposit boxes — in some states they can be sealed at death, locking your will inside just when it's needed.
• Tell a trusted person where it is. You don't have to share the contents — just make sure someone knows where to look.
• Give your executor and agents copies, or tell them how to get access, so they can act without delay.
• Keep originals safe but findable — a fireproof box or home safe is ideal, as long as the right people can open it.
