Guide to Estate Planning

Why this guide exists

A man updates his will a few months after remarrying, leaving everything to his new wife. He never reopens the 401(k) from an old job, where the beneficiary form still names his ex. When he dies, that form wins — the account pays the ex, and the up-to-date will doesn’t get a say. It happens constantly, and rarely to anyone who pictures themselves as having an “estate.”

That last word is the problem. Most people hear “estate planning” and picture the very wealthy moving fortunes around to dodge taxes. The picture is wrong for almost everyone, and it keeps young adults from doing the small handful of things that actually matter.

Estate planning is deciding, in advance, three plain things:

1. Who gets what you leave behind.
2. Who’s in charge of making that happen.
3. Who raises your children if you and their other parent can’t.

None of that is about being rich. It’s about not leaving those choices to a court, a stale form, or a default rule written by your state. This is the stewardship side of money: you spend a life building something, and a little planning makes sure it lands where you meant it to.

Your will — and what it can’t do

A Will is the document that names who receives the assets that pass through your estate, names the person who settles it (the executor — the one who pays the final bills and distributes what’s left), and, most important for young parents, names a guardian for your minor children. That last part is the single biggest reason for a twenty-something or thirty-something to have one: it’s the only place you get to say who raises your kids.

If you die without a will, you die Intestate, and your state’s default order decides who inherits — and a judge, with no instruction from you, decides who raises your children. The default rarely matches what you would have chosen.

Nothing brings this home faster than a new baby. The new-baby Moment puts naming a guardian and fixing your beneficiary forms first on the list — ahead of the college fund everyone asks about.

But a will has a real limit, and it surprises people: it controls the assets that pass through it, and nothing more. A large share of what you own is set to skip the will entirely. That’s the next section, and it’s the part most people get wrong.

Beneficiary designations beat your will

Your retirement accounts and life insurance don’t read your will. They pay whoever is listed on their own beneficiary designation — the form you filled out (or skipped) when you opened the account. That named person inherits directly, outside the will, and the designation overrides whatever the will says.

This is power and trap in equal measure:

• The power: named money skips Probate — the public, sometimes slow court process that validates a will and transfers what passes through it. A beneficiary gets the account in weeks, privately, no court required.
• The trap: the form is frozen until you change it. The ex-spouse case from the top of this guide is the classic one — whatever the form says beats the will, no matter what you wrote later. The new will naming your current spouse and kids does nothing on its own.

The fix takes one afternoon. Pull up every account that has a beneficiary field: 401(k), IRA, HSA, life insurance, pension. For a 401(k) the form lives in your plan administrator’s portal (Fidelity, Vanguard, Empower, or whoever your employer uses), not with HR; for life insurance it’s with the insurer. Confirm the named person and a named backup (the contingent beneficiary, who inherits if the primary is gone) are still right. Do it again after any marriage, divorce, birth, or death in the family. One account on that list carries a tax risk the others don’t: an HSA left to anyone but a spouse loses its tax shelter entirely, landing on the heir as a lump of ordinary income in a single year. The spouse designation there is worth a second look; the HSA guide explains why.

TOD and POD: probate-free transfer

Bank and brokerage accounts have their own version of a beneficiary form, and it’s one of the most useful, least-known tools here. A

registration names who inherits the account directly at your death:

• TOD (transfer on death) — for brokerage and investment accounts.
• POD (payable on death) — the same idea for bank accounts.

While you’re alive, nothing changes: the account is fully yours, the named person has no access and no say. At your death it passes straight to them, skipping probate, with no will entry needed. Adding a TOD or POD is usually a free, five-minute change: look for a “Beneficiaries” or “Transfer on death” section in your account settings, or call the institution and ask.

A related idea for the largest asset most people own: many states offer a transfer-on-death deed for a home, which passes the house outside probate the same way. Availability and rules vary by state, so this is one to confirm locally rather than assume — a local estate attorney or your county recorder’s office can tell you whether your state offers one.

Will the estate tax touch you?

Almost certainly not. The federal estate tax applies to estates above the exemption, and for 2026 that exemption is $15,000,000 per person — so a married couple can pass roughly $30,000,000 before a dollar of federal estate tax is owed. The 2025 One Big Beautiful Bill Act made this level permanent (it had been scheduled to fall by roughly half) and indexes it to inflation going forward.

In practice, fewer than one estate in a thousand owes any federal estate tax. Unless your estate could approach the exemption above, this is not the part of estate planning to spend energy on — the will and the beneficiary forms are.

One adjacent number worth knowing: the annual gift-tax exclusion lets you give up to $19,000 per person per year to as many people as you like with no tax filing and no dent in your exemption. It’s how grandparents quietly help with a 529 plan or a first home.

What this guide doesn’t cover

Three things sit outside this guide on purpose:

• Incapacity, not inheritance. A healthcare directive (a written statement of your medical wishes for when you can’t speak for yourself) and a durable power of attorney (someone you authorize to handle money and decisions while you’re incapacitated — “durable” because it survives that incapacity) are about while you’re living, not what you leave behind. They belong in a complete plan, but they’re a separate topic from the transfer-at-death basics here.
• Trusts. A revocable living trust can be worth it for larger or more complicated estates, mainly to avoid probate across multiple assets. For most young savers, a will plus correct beneficiary and TOD/POD designations does the same job with far less cost and complexity.
• Inheriting, not leaving. This guide covers what you leave behind. It doesn’t cover the other side: being the one who inherits an account, where the kind of account sets both your tax bill and your deadline — and cashing it out too fast can’t be undone. That’s the I inherited a portfolio lesson.

Common ways people get stuck

• “I’ll do it when I’m older / have more.” Naming a guardian for your kids and fixing your beneficiary forms matter most when you’re young and your kids are small. Waiting is the risk.
• A will, but stale beneficiary forms. The most common real-world failure. The will is immaculate; the 401(k) still names an ex. The account wins. Check the forms.
• No contingent beneficiary. Naming only one person, with no backup, means that if they predecease you the asset falls back into probate anyway. Always name a backup.
• Treating it as a one-time task. Marriage, divorce, a new child, a death — each is a trigger to re-check the will and every beneficiary form. Set a reminder to glance at them every few years regardless.
• Assuming you’re too “normal” to need any of it. Guardianship and clean beneficiary forms are exactly the ordinary, not-wealthy person’s tools. This is the plain version of stewardship: leaving things in order for the people who depend on you.

None of this takes a lawyer’s retainer or a free weekend. Here’s the short list, in the order worth doing it. Tick what’s already true — the first unchecked item is your next move.
