Most estate planning advice is written for parents. It assumes you have children who will inherit your assets, act as guardians for other children, and handle your affairs when you can no longer. For childfree people, none of those defaults apply, and the consequences of doing nothing are worse, not better.

When a parent dies without a will, assets typically flow to a surviving spouse or children. When a childfree person dies without a will, assets flow through intestate succession laws, which vary by state but generally pass assets to parents, then siblings, then more distant relatives, regardless of your actual relationships or intentions. If you have a partner you're not married to, they get nothing by default. If you've been estranged from your family for twenty years, they may inherit everything.

Estate planning for childfree people is not optional busywork. It's the mechanism by which your actual wishes, about money, medical care, and what happens to your body, get enforced.

The four documents everyone needs

1. Will

A will directs where your assets go and names an executor to administer your estate. Without one, the state decides. For childfree people, the key decisions in a will are:

  • Who inherits your assets (partner, friends, siblings, charities)
  • Who serves as executor (the person who handles paperwork, pays debts, distributes assets; choose someone organized and trustworthy, not just the obvious family member)
  • What happens to pets (name a caretaker and consider leaving funds for their care)

A simple will can be created through an attorney for $300-$800, or through services like Trust & Will or LegalZoom for $100-$200. An attorney is worth it if your situation is complex (business ownership, property in multiple states, significant assets).

2. Durable power of attorney

This document designates someone to handle your financial affairs if you become incapacitated: paying bills, managing investments, filing taxes. Without it, a court appoints a guardian, which is expensive, slow, and may result in someone you wouldn't choose controlling your finances.

For childfree people without a spouse, this is especially important. Name someone you trust: a partner, a close friend, a sibling. Make sure they know where your accounts are and how to access them.

3. Healthcare proxy / medical power of attorney

This designates someone to make medical decisions on your behalf if you can't make them yourself. This is the person who talks to doctors, decides on treatment options, and ultimately makes end-of-life decisions if it comes to that.

For childfree people, this is often the document that causes the most friction. Hospitals default to next-of-kin, which may be a family member you're not close to or a relative who doesn't know your values. A healthcare proxy legally supersedes next-of-kin in most states. Name someone who knows how you think about medical intervention, quality of life, and end-of-life care.

4. Advance directive / living will

This documents your wishes directly: what medical interventions you do and don't want, under what circumstances. It reduces the burden on your healthcare proxy and removes ambiguity. Specify your views on resuscitation, mechanical ventilation, artificial nutrition, and organ donation.

These can be completed online through your state's health department forms or through Five Wishes, a nationally recognized advance directive document.

What childfree people get wrong

Assuming a partner is covered. If you're not married, your partner has no legal standing by default: not for medical decisions, not for inheritance, not for anything. A will, healthcare proxy, and beneficiary designations are what actually protect an unmarried partner.

Forgetting beneficiary designations. Retirement accounts (401k, IRA), life insurance policies, and many bank accounts pass by beneficiary designation, not through your will. These designations supersede whatever your will says. If your IRA still lists a parent or ex-partner as beneficiary, that's who gets the money, regardless of what your will says. Review all beneficiary designations when you set up estate documents and after any major life change.

Not naming a successor beneficiary. Name a primary beneficiary and a contingent (backup) beneficiary on every account. If your primary beneficiary dies before you and you haven't named a contingent, the account goes through probate.

Ignoring the executor role. The executor of your estate handles a significant administrative burden, sometimes for months. Don't name someone out of obligation. Name someone organized who is willing to do paperwork and won't be overwhelmed by the responsibility.

The childfree-specific decisions

Who gets the money? Without children as default heirs, you have full flexibility. Common choices among childfree people:

  • A partner (married or unmarried)
  • Close friends, especially friends who have been family in the way that family sometimes isn't
  • Siblings or other relatives you're actually close to
  • Charitable organizations whose work you care about
  • A combination

There is no correct answer. The point is to decide deliberately rather than let the state decide for you.

Pets. This often goes unaddressed. Name a specific person as caretaker in your will and consider a pet trust, a legal structure that holds funds specifically for the animal's care. A pet trust is enforceable in all 50 states; a simple instruction in a will is not legally binding on the caretaker.

Long-term care. Childfree people often have no adult children to serve as informal caregivers in old age. That gap requires deliberate planning. Long-term care insurance, purchased in your 40s-50s before premiums spike, is one option. Another is building a financial cushion specifically for care costs. The median annual cost of assisted living is around $54,000 and nursing home care is $94,000-$108,000 (Genworth 2024 data).

The childfree DINK wealth advantage is worth directing some of toward the cost of aging without a family support network.

How to actually get this done

The biggest barrier to estate planning is inertia, not complexity. A basic estate planning package (will, power of attorney, healthcare proxy, advance directive) takes one or two attorney meetings and a few hours of your time. Cost is typically $500-$1,500 for a straightforward situation.

If you want to start immediately: Trust & Will and LegalZoom both offer online document creation for under $200. These are adequate for simple situations. Use an attorney if you have a domestic partnership, real estate in multiple states, a business interest, or significant assets.

Do it now. The people who most need these documents are the ones who don't have them, and the people most likely not to have them are people who are young and healthy and assume there's time.

There is time. But this is also the kind of thing that's much harder to set up when you actually need it.
