The core four documents (every adult)

  1. Last will and testament: names guardians for minor kids, an executor, and who gets your probate assets. Without one, your state decides — via a formula that may not match your wishes at all.
  2. Durable financial power of attorney: lets someone you trust pay bills, manage accounts, and handle money if you're incapacitated. "Durable" means it survives incapacity — that's the whole point.
  3. Healthcare power of attorney / proxy: names who makes medical decisions if you can't.
  4. Living will / advance directive: your wishes on life support, resuscitation, organ donation. Spares your family agonizing guesses.
Without these, a court decidesIncapacity without a POA means a court-appointed guardian — slow, public, expensive. Dying without a will ("intestate") means state law splits your assets by formula. These four documents prevent both, and they're the highest-value paperwork in personal finance.

Will vs revocable living trust

WillRevocable living trust

IncapacityDoes nothing until deathSuccessor trustee manages assets seamlessly
PrivacyPublic recordPrivate
EffortSign and doneMust retitle assets into the trust or it's useless

Rule of thumb: a will suffices for simple situations. Consider a trust if you own real estate (especially in multiple states), have minor kids (a trust can hold and manage their inheritance until they're mature — 25, 30, staggered), want privacy, or live in a state with slow/expensive probate (looking at you, California).

A trust does not avoid estate taxes by itself — revocable trust assets are still in your taxable estate. Tax-focused irrevocable trusts are a separate, advanced tool.

Kids: the guardianship conversation

  • Name a guardian (raises them) and ideally a separate financial trustee (manages money) — the best caregiver isn't always the best money manager.
  • Name backups. Talk to the people first — a surprise guardianship is a burden, not an honor.
  • Leave a letter of intent: values, schooling wishes, medical notes, where the money is. Not legally binding, but invaluable.
  • Never leave large sums outright to minors — courts will appoint a stranger to manage it until 18, then hand your teenager a lump sum. A trust with staggered distributions (⅓ at 25, ⅓ at 30, ⅓ at 35) is the standard fix.

Beneficiaries beat wills — check them

Beneficiary designations on 401(k)s, IRAs, life insurance, and payable-on-death accounts override your will. The #1 estate-planning disaster is an ex-spouse still listed on a 401(k) from 15 years ago.

  • Review every beneficiary after marriage, divorce, births, and deaths
  • Name contingent beneficiaries (the backup if the primary dies first)
  • For minor kids: name the trust as beneficiary, not the child directly
  • Keep a one-page "where everything is" list with your will (accounts, advisors, passwords location — not the passwords themselves)

Estate & gift taxes in 2026

2026 federal figures Estate/gift/GST exemption: $15,000,000 per person ($30M per couple with portability) — made permanent by the One Big Beautiful Bill Act (signed July 2025), indexed for inflation from 2027 · Top rate: 40% above the exemption · Annual gift exclusion: $19,000 per recipient · Step-up in basis at death: preserved

Translation: fewer than 0.1% of estates owe federal estate tax. But two things still matter for everyone:

  • State estate taxes: about a dozen states (plus DC) tax estates at much lower thresholds — some around $1–7M. If you live in one, plan for it even if federal tax is irrelevant.
  • Step-up in basis: heirs generally inherit appreciated assets (stock, real estate) at current market value — wiping out the capital-gains tax. This is why "don't sell, let heirs inherit" is often the right move for highly appreciated assets.

For large estates: lifetime gifting moves future appreciation out of the estate; portability lets a surviving spouse use the deceased spouse's unused exemption (but requires filing an estate tax return to claim it); irrevocable trusts (SLATs, GRATs, ILITs) are advanced tools — get a real estate attorney, not a website.

Probate, simplified

Probate is the court process of validating your will and distributing assets. It takes 6–18 months, costs 3–7% of the estate in some states, and it's public. Assets that skip probate: anything with a beneficiary designation, jointly owned property with survivorship rights, and assets titled in a living trust. That's why the beneficiary check above matters more than most people realize.

Special situations

  • Blended families: "everything to my spouse" can accidentally disinherit your kids. A trust with a lifetime income interest for the spouse + remainder to kids is the standard solution.
  • Special-needs child: a special needs trust provides for them without disqualifying means-tested benefits (Medicaid, SSI). Never leave assets outright.
  • Digital assets: list crypto wallets, seed phrases (stored securely, separately), and online accounts. Most states now have digital-asset access laws — name a digital executor.
  • Business owners: a buy-sell agreement + succession plan is your business's will. Without it, your family inherits a company they can't run. See Business Owners.
  • Unmarried partners: you have zero default rights — no intestate inheritance, no medical decision-making. Documents aren't optional here.

What it costs (and when to DIY)

  • Simple will + POAs: $300–1,000 with an attorney; reputable online services run $100–300 and beat having nothing.
  • Living trust package: $1,500–4,000+.
  • Complex/taxable estates: $5,000–15,000+ — money well spent at 40% tax rates.
  • Review every 3–5 years and after every major life event. An outdated plan can be worse than none (see: ex-spouse beneficiaries).

FAQs

Do I really need a trust?

Not necessarily. If your assets are modest, beneficiaries are current, and your state has simple probate, a solid will + POAs + correct beneficiaries covers ~90% of needs. Get a trust when you have minor kids, real estate in multiple states, privacy concerns, or a taxable estate.

Can I write my own will?

Holographic (handwritten) wills are valid in about half the states but are the most contested documents in probate. A $200 online will executed correctly (witnesses, notarization per your state) beats a handwritten one. For anything beyond simple, hire the attorney.

What happens to my 401(k) when I die?

It goes to your named beneficiary — not through your will. Spouses can roll it into their own IRA; non-spouse beneficiaries generally must empty inherited IRAs within 10 years (SECURE Act). Keep beneficiaries current.

How do I pick an executor/trustee?

Choose organization and integrity over proximity: a responsible sibling beats a nearby flaky one. Name a backup. For complex estates, a professional trustee (bank/trust company) is worth the ~1% fee. Tell them where the documents are.
