Estate planning checklist for new parents

A birth or adoption is the right trigger — not a tax cliff. Here is the Essentials path for households with children under 18: guardianship, will, healthcare, POA, beneficiaries, and life insurance coordination.

Key facts

  • Americans with children under 18 are the largest cohort without wills or other estate-planning documents (Caring.com 2025 Wills and Estate Planning Study).
  • Only 24% of surveyed American adults reported having a will in 2025 — down from 33% in 2022 (Caring.com / YouGov).
  • Guardian-nomination rules are state-specific. In Delaware, a sole surviving parent may nominate a guardian by written declaration or will; the Court of Chancery appoints that nominee absent just cause.
  • Retirement-plan, IRA, and life-insurance death benefits generally follow their governing documents and applicable law rather than the will; spousal rights, court orders, and policy terms can affect the result.
  • Unmarried children of a deceased worker may qualify for Social Security survivors benefits if under 18 (or 18–19 and in K–12 full time, or disabled before age 22) — SSA.gov survivors eligibility.
  • Money for a minor can be held in a trust or under a Uniform Transfers to Minors Act (UTMA) custodianship; the person raising the child need not be the same person managing the money.

The night you brought them home — and the plan you postponed

A couple leaves the hospital with a newborn, a car seat, and a mental list that starts with pediatrician visits and ends somewhere near "we should update the will." Months later the will is still a blank Google Doc. The 401(k) still names a sibling from before the marriage. Nobody has agreed who would raise the child if both parents were gone. The checklist below turns that gap into concrete decisions.

Caring.com's 2025 survey found that adults with children under 18 are the largest group without wills or other estate documents. The trigger is not a multi-million-dollar tax problem. It is guardianship, incapacity, and who can actually access the accounts that feed the household.

What "Essentials" means when you have kids

For new parents, the useful order matches how most family-office checklists (and Elephant's starter tasks) are built — people first, then documents:

1. Name the household: spouse or co-parent, children, and the people you would trust in a crisis. 2. Nominate a guardian (and at least one alternate) for each minor. 3. Draft a will that carries that nomination and names an executor. 4. Complete an advance healthcare directive and a HIPAA authorization so someone can talk to doctors. 5. Sign a durable financial power of attorney so bills and payroll keep moving if you are alive but incapacitated. 6. Align beneficiary forms on every retirement account and life-insurance policy. 7. Put signed copies and account maps in one place your co-pilot can find.

A revocable living trust can wait until the Essentials are moving — unless you already know you want probate avoidance and staggered distributions for the kids. An empty trust helps nobody; a funded one is a later step.

Guardianship: the line that cannot wait

Guardian rules vary by state. In Delaware, a sole surviving parent may nominate a guardian by written declaration or will, and the Court of Chancery appoints the nominee absent just cause. Separate Family Court guardianships involving living parents use different statutory grounds and, where applicable, a best-interest finding.

Always name an alternate. Revisit when your children age, when a nominee moves, divorces, or has their own health crisis, or when your relationship with that person changes. Talk to the people you nominate before you put their names on paper — surprise nominations create reluctant guardians.

Separate "who raises" from "who holds the money." Guardianship of the person and management of property can be different roles. A trust or UTMA custodianship may name a trustee or custodian who is not the day-to-day caregiver. In Delaware, a property guardianship generally ends at 18, while UTMA transfers can terminate at 18 or 21 depending on how the transfer was created.

The will, the forms that beat the will, and life insurance

A will directs probate assets, names an executor, and may nominate guardians. It does not retitle a 401(k), IRA, or life-insurance policy. Those arrangements generally follow valid beneficiary designations and governing terms, subject to spousal rights and applicable law. After a birth or adoption, audit primary and contingent beneficiaries and whether naming a minor outright may require court-supervised property management under state law.

Life insurance can be an important source of support for a young family. Confirm ownership, beneficiary designations, and whether the death benefit would reach the intended caregiver or a trust for the children. Coordinate the policy with the will and any trust so the documents do not point in different directions.

SSA lists survivor-benefit eligibility for unmarried children age 17 or younger, ages 18–19 in K–12 full time, or any age if disability began at age 21 or younger. Stepchildren, adopted children, grandchildren, and others may qualify in specified circumstances. Benefits do not replace a will or guardian nomination.

Incapacity while you are very much alive

New parents may focus on death scenarios and skip another crisis: a car accident or medical emergency while the kids still need school pickup, mortgage payments, and someone who can authorize care. A durable financial power of attorney names an agent who can act if you cannot. An advance healthcare directive plus HIPAA authorization addresses who decides about treatment and who may receive medical information.

Without those documents, authority may depend on state default rules, a court process, and each institution's requirements. Follow state execution rules and store copies where the named agents can find them.

A practical first-week checklist

Day 1–2: Agree with your co-parent on guardian and alternate names; call those people. List every retirement account and life-insurance policy you can find.

Day 3–4: Draft or update the will (including guardian nominations and executor). Start healthcare directive, HIPAA authorization, and durable POA — same sitting if you can.

Day 5–7: File updated beneficiary designations; save confirmations. Upload signed PDFs and the account list to a shared vault. Tell one co-pilot where everything lives.

Within 30 days: Revisit whether a revocable trust or UTMA structure is worth adding for life-insurance proceeds; set a calendar reminder to re-check after the next birthday, move, or job change.

Questions worth asking before you call it done

If both of us were gone tomorrow, who raises our children — and have they said yes?

Who manages money for the kids, and is that the same person as the guardian?

What does every 401(k), IRA, and life-insurance form say today — primary and contingent?

Could our healthcare agents and financial agents act this week if one of us were in the hospital?

Where are the signed documents, and can a co-pilot find them without unlocking our phones?
