Updated August 4, 2026. Quick answer: five documents cover most people, but the useful question is not which documents exist — it is which gaps your own situation makes expensive. Each line below names the consequence of skipping it and links the page that closes it. Nothing here is legal advice.
Printable: plain lists, no interactive parts — it prints as a checklist from any browser.
The five most people need
- A valid will — not just a will — a will executed the way your state requires. Witness count and notarisation are what decide validity, and they are the most common reason a homemade will fails
- A financial power of attorney — the document that matters most while you are alive. Without it, someone has to petition a court for guardianship to pay your bills
- A health-care directive and proxy — two different jobs: what you want, and who decides. Many people have one and assume it does the other
- Beneficiary designations, checked this year — they override the will. An ex-spouse on a 401(k) form beats any will ever written
- POD or TOD on the accounts that should skip probate — the cheapest probate avoidance there is, and it takes a form
If you have none of these, the order that removes the most risk fastest is: beneficiary designations first (free, same day), then the financial power of attorney, then the will. That order surprises people, and it is right because the POA is the one that matters while you are alive.
A straightforward estate — one state, no business, no disabled beneficiary, no blended-family conflict — is one of the few legal jobs where a form is genuinely enough, provided your state’s execution rules are followed exactly. Where it is not, the case for a lawyer is set out plainly, including the situations where a form is a false economy. What each route costs is at how much does a will cost.

Gaps your situation creates
The default advice assumes a married couple, adult children, one house, one state. Where that is not the shape of it, these are the gaps that cost real money:
- A blended family — the intestacy default splits the estate with children from an earlier relationship — and it is the single most expensive gap on this list
- A house in a probate-heavy state — a transfer-on-death deed, where the state authorises one, keeps it out of probate entirely
- An estate large enough for a trust to pay for itself — the question is arithmetic: the probate fees a funded trust avoids against what the trust costs
- A disabled beneficiary — an outright inheritance can end means-tested benefits; the trust type matters and the two are not interchangeable
- No children or close family — the intestacy ladder is long, and naming someone is the whole point
- A non-citizen spouse — the unlimited marital deduction does not apply, which changes the tax answer completely
- Crypto or digital assets — assets nobody can find are assets nobody inherits
- Firearms — transfer rules are federal and state, and an ordinary bequest can be an illegal transfer
The maintenance nobody does
A plan signed and filed is not a plan finished. These are the failures that show up at settlement, when they cannot be fixed:
- Fund the trust you paid for — an unfunded trust does nothing at all — this is the most common expensive mistake in estate planning
- Retitle the accounts — the trust only governs what is actually in it
- Redo designations after a marriage or divorce — some are revoked automatically by state law and some are not; assuming either way is the risk
- Keep the trust’s schedule current — assets bought after the trust was signed are not in it by default
- Re-check everything after a move — execution rules, elective share, community property and probate cost all change with the state
What happens if you do nothing
Your state’s intestacy statute becomes your will, and it is not the one most people would have written — see dying without a will, where the spousal share and the definition of “by representation” are quoted from the statute. If you are here because someone has already died, the sequenced version is the financial checklist after a death.
The whole machine — documents, process, taxes, tools — is on the estate planning front door. Method: methodology. Mistakes: corrections.
Comparing the products themselves? Online will makers compared quotes only the prices we read from each company’s own page, discloses our one affiliate relationship in the table rather than a footer, and leads with the thing none of them control — your state’s execution rules.
Unfamiliar word? The estate planning glossary defines 32 terms without circularity — ademption, abatement, per stirpes, elective share — each with its own link anchor, and each state-specific term routed to the page that cites the statute.
The stage after signing. A finished estate plan still ages: the events that require an update, and whether to amend or replace.
Two items on this list are commonly left for later and are the hardest to fix afterwards — provision for an animal and, where a partnership is not a marriage, the documents that carry the relationship.
One beneficiary check that belongs on this list and is almost never on anyone’s: on a life insurance policy, the owner, the insured and the beneficiary can be three different people — and when they are, the death benefit can arrive as a taxable gift rather than as insurance proceeds.
