Wills, Beneficiaries & Guardianship

Every account this site teaches you to open — the 529s, the custodial Roths, the brokerage, the insurance — ultimately serves one purpose: taking care of your family. This page is about making sure that purpose survives you. It is the least pleasant hour of financial planning, and among the highest-leverage.

Beneficiaries: The Designation That Overrides Your Will

Start here, because it is free, takes twenty minutes, and fixes the single most common estate mistake: beneficiary designations override your will. The named beneficiary on your 401(k), IRA, HSA, life insurance, and any payable-on-death bank account receives that money directly — regardless of what your will says, regardless of what everyone knows you intended. The ex-spouse still named on a twenty-year-old 401(k) inherits it. Courts enforce the form, not the intention.

So tonight’s homework: log into every account and check. Name primary and contingent beneficiaries, never name a minor child directly (the reason is the next section), and re-check after every milestone — marriage, divorce, each birth, each death. This is the same once-a-year glance recommended in Insurance Basics; put them on the same calendar entry.

The Will — and the Guardianship Decision Inside It

For parents of minor children, the will’s most important job has nothing to do with money: it names the guardian. Die without one and a judge chooses, knowing nothing about your family beyond the paperwork, while relatives potentially disagree in the hallway. No account balance compensates for skipping this page of the document.

Choosing is genuinely hard — values, parenting style, age and health, location, willingness, and the honest acknowledgment that the person best with your kids may not be best with money (you can split the roles: a guardian for the children, a separate trustee for the funds). Name a backup. Ask the people first. Revisit the choice every few years as kids and candidates age. The rest of the will directs property that lacks beneficiary designations and names your executor — important, but the guardianship clause is why parents cannot postpone this document.

Leaving Money to Minors (Without Leaving a Mess)

Minors cannot directly inherit meaningful money — which is why naming a child as your life insurance beneficiary creates exactly the court-supervised mess you were trying to avoid, followed by an unconditional handover at the age of majority. Readers of this site already know that cliff: it is the UTMA transfer problem at estate scale. The standard solutions, in increasing order of control: a UTMA designation (simple, but transfers fully at 18–21), or a trust for the children’s benefit — commonly a testamentary trust written into the will — with a trustee you choose and distributions at ages and purposes you set. As I noted in Childhood Foundations, trusts are more formal, usually need a lawyer, and cost real fees — and for life-insurance-sized sums landing on grieving teenagers, that control is exactly what you are paying for. Whatever structure you choose, the deepest protection remains the one this whole site builds: a child raised on jars, ledgers, and earned dollars who can handle the money when it arrives.

The Living Documents: POA and Healthcare Directives

Estate planning is not only about death — incapacity is the likelier event during your parenting years, which is why disability insurance and these documents travel together. A durable financial power of attorney lets your chosen person pay the mortgage and run the accounts if you cannot; without it, your spouse may need a court order to manage what you assumed was shared. A healthcare proxy and advance directive name who decides medically and what you want decided. And once a child turns 18, the law considers them a stranger to you: a college student needs their own healthcare proxy and HIPAA release, or you may learn about their emergency from a hospital that cannot legally discuss it. Add that to the launch checklist in Teen & College.

What Happens to the Kids’ Accounts

The accounts you opened for the children mostly take care of themselves — with details worth knowing. The custodial accounts (UTMA/UGMA, custodial Roth) are already the child’s property; your death changes the custodian, not the owner — name a successor custodian where the brokerage allows it, or the court appoints one. The 529 is the reverse: it is your asset, so name a successor owner (typically your spouse, then a trusted relative) so control passes cleanly; the beneficiary child is unaffected. And your own retirement accounts flowing to your spouse, then contingently to children or their trust, complete the picture — the tax treatment of inherited accounts is genuine CPA territory, but the designations are yours to set correctly today.

The Family Binder

The final document is the humble one: a binder (or an encrypted file, with access where your spouse and executor can get it) listing every account and institution, the insurance policies, where the estate documents physically are, the attorney’s name, and the bills that keep the household running. Estates with organized records settle in months; estates without them generate a scavenger hunt for grieving people. You already keep a one-page ledger for the kids’ earned income — this is the same habit at family scale, reviewed on the same annual calendar entry as the beneficiaries and the insurance.

The categories most families forget

Working through the standard references — including the federal Emergency Financial First Aid Kit, which is the closest thing to an official version of this document[7] — four categories come up again and again as the ones people leave out:

• Digital life. The fastest way to lock a family out. Primary email accounts matter most, because password recovery for everything else runs through them. Add the password manager and its emergency access, legacy contacts on Apple, Google, and Facebook, cloud photo storage, domains, and — if it applies — where a crypto seed phrase or hardware wallet physically lives. That last one has no recovery path at all: lose it and the money is simply gone.
• Vital records. Birth certificates, Social Security cards, marriage certificate, divorce decree, and military discharge papers. The DD-214 is the one worth singling out — without it a veteran’s family may not be able to claim burial benefits or survivor benefits they are entitled to, and it is far harder to obtain after the fact than before.
• Items of value. Not just what is valuable, but where it is, whether it has been appraised, and who it is meant for. Firearms deserve their own line, because how they may lawfully transfer varies by state and an executor who guesses can create a genuine legal problem.
• Final wishes. Burial or cremation, any prepaid arrangement, the cemetery plot deed, and a written list of people to notify. None of this belongs in a will — wills are often not read until after the funeral, which is exactly the wrong order.

Final Thought

Twenty minutes of beneficiary checks tonight, a will with a guardianship clause this season, the living documents alongside it, and a binder your family could actually use. Then close the drawer and get back to the building, knowing the structure stands even on the day you cannot hold it up. The author is not an attorney; estate law varies by state — use a qualified estate attorney for documents and a CPA for inherited-account tax questions.
