The honest one-paragraph answer
If you have any of these, you should write a will:
- Minor children. A will is the only document that names a guardian for them.
- Real estate titled solely in your name.
- Specific wishes about who inherits what (specific items to specific people, charitable gifts).
- A blended family or any situation where the default state intestacy rules wouldn’t match what you’d choose.
- Substantial assets that don’t have named beneficiaries.
If none of those apply — you’re single, no kids, no real estate, your retirement accounts and life insurance all have current named beneficiaries, your bank accounts have POD designations — a will is still useful, but the urgency is lower. The default state intestacy rules will probably distribute your remaining assets to your closest living relatives in a reasonable way.
For most American adults, the honest answer is: yes, write a will. It’s a few hundred dollars and a couple of hours of decisions. It removes a meaningful source of stress and risk for the people who’d be sorting out your affairs.
What happens if you don’t have a will
Every US state has an intestacy statute — a default order of inheritance that kicks in when you die without a will. The details vary, but the general pattern in most states:
- Surviving spouse and children inherit first (in shares set by state law).
- If no spouse or descendants, then parents.
- Then siblings, then more distant relatives.
- If no relatives can be found, the property eventually escheats to the state.
For some families, the default works fine. For others, it creates real problems.
What intestacy CAN’T do
- Leave anything to a partner you’re not legally married to. Intestacy doesn’t recognize unmarried partners — even if you’ve lived together for 30 years.
- Leave anything to a step-child you didn’t formally adopt.
- Leave anything to a charity, friend, or specific person outside your family.
- Name a guardian for your minor children. A judge picks, based on what they think is in the children’s best interest.
- Specify who handles your estate. A judge appoints an administrator, usually a close relative.
- Specify specific items — your grandfather’s watch, the family photo album, your music collection. Everything gets pooled and distributed by formula.
- Account for blended families in any nuanced way. State formulas often produce results that don’t match what most people would want.
What intestacy CAN do
For someone in a clean situation — happily married first marriage, biological children only, modest assets, no specific bequests — intestacy can produce a result close to what a simple will would have produced anyway. It still doesn’t name a guardian for minor children, and it doesn’t avoid probate, but the inheritance distribution may be acceptable.
Specific situations where a will is essential
You have minor children
This is the single most important reason for parents to have a will. Without one, a judge picks the guardian for your kids if both parents die. The judge does their best, but they don’t know your family, your values, or your kids’ relationships. You do.
A will lets you name:
- The guardian for your minor children (and a backup).
- The person who manages money for the children’s benefit until they’re adults (sometimes the same person as the guardian, sometimes different).
- The age at which children inherit outright — many parents leave assets in trust until age 25 or 30 rather than handing 18-year-olds a large inheritance.
For parents with young children, a will is not optional. It’s the document that makes sure your kids are cared for the way you’d want.
You own real estate in your name alone
Real estate titled solely in your name has to go through probate to transfer to anyone. A will doesn’t avoid probate, but it directs who gets the property. Without a will, intestacy decides.
If you own real estate jointly with a spouse (joint tenancy with right of survivorship), the property passes automatically to the survivor — no will needed for that asset. But if you’re single, divorced, widowed, or the sole owner of investment property, the will controls.
You’re in a non-traditional family situation
Intestacy is written for the traditional nuclear family. If your situation doesn’t match — unmarried partner, blended family, estranged relatives you don’t want to inherit, beloved step-children you do want to inherit — a will is the only way to get the distribution you actually want.
Example situations where intestacy produces unwanted results:
- An unmarried couple of 20 years where one partner owns the home.
- A second marriage with children from a prior relationship.
- A childless adult who wants to leave the estate to a friend, charity, or favorite niece — not to estranged siblings.
- A same-sex couple in a state that may not recognize a domestic partnership for inheritance purposes (mostly resolved post-Obergefell, but worth confirming).
You have specific bequests in mind
A will lets you direct specific items to specific people: “my grandmother’s silver to my daughter,” “my book collection to my brother,” “$10,000 to my church.” Intestacy can’t do any of that.
You want to control who serves as executor
A will names the executor — the person who handles your estate. Without a will, the court appoints an administrator, who may not be the person you’d have chosen.
This matters because executor selection affects:
- How efficiently the estate is settled. A capable, organized executor can close an estate in months; a disorganized or absent one can drag it out for years.
- Family dynamics. Default selection (a close relative chosen by the court) sometimes triggers conflict; a will lets you head off the predictable arguments.
- Cost. Some states pay executors a percentage of the estate. Naming a family member who’ll waive the fee saves real money.
Situations where a will is less urgent
A will is still useful in these situations, but the consequences of not having one are smaller:
- You’re single with no children and no dependents.
- You don’t own real estate.
- All your major assets (retirement accounts, life insurance, brokerage accounts, bank accounts) have current named beneficiaries or POD/TOD designations.
- You’re satisfied with intestacy’s likely outcome — usually your closest living relatives inheriting in default shares.
Even in these situations, a basic will:
- Removes any ambiguity about who handles your affairs.
- Lets you name specific people for specific items.
- Lets you leave gifts to friends or charities.
- Handles the catch-all (anything you forgot to put a beneficiary designation on).
But the urgency is lower. A 28-year-old single graduate student with $20,000 in a retirement account, current beneficiary designations, and no dependents doesn’t have an immediate crisis without a will. They should still write one when convenient, but it’s not the same priority as for a parent with minor children.
What a will doesn’t do (so you don’t over-rely on it)
A common misunderstanding: people think the will handles everything. It doesn’t.
- A will does NOT avoid probate. A will goes through probate. To avoid probate, you need beneficiary designations, joint ownership, TOD deeds, or a funded living trust. See How to Avoid Probate.
- A will does NOT override beneficiary designations. Your 401(k) beneficiary form controls who gets your 401(k) — regardless of what your will says.
- A will does NOT take effect while you’re alive. For incapacity, you need a power of attorney and a healthcare directive.
- A will does NOT control joint property. Joint tenants with right of survivorship pass automatically to the survivor.
A will is one component of an estate plan, not the whole thing. See our Estate Planning Checklist for the full picture.
A simple decision sequence
If you don’t have a will, this is the honest priority order:
- Do you have minor children? → Write a will this month. Name a guardian.
- Do you own real estate in your name alone? → Write a will. Don’t leave the distribution to intestacy.
- Do you have a non-traditional family situation? → Write a will so your wishes (not the state’s defaults) control.
- Do you have specific bequests in mind? → Write a will.
- None of the above? → A will is still useful, but you have more flexibility on timing. Plan to write one within the next year.
How to actually do it
Three honest paths:
- Online service ($50–$300) — best for clean cases. Trust & Will, Quicken WillMaker, LegalZoom, FreeWill.
- Local attorney ($300–$1,500 for a basic plan) — best for anything not obviously simple, anyone with substantial assets, anyone with complicated family situations.
- DIY template — works for the very simplest cases but easy to make signing or witness mistakes. Higher risk.

A few more honest points
- You can write a will once and update it. It’s not a one-shot decision. Most estate attorneys recommend reviewing every 3–5 years or after any major life event.
- A will is not just for the wealthy. It’s for anyone with a person they want cared for or an item they want to go somewhere specific.
- A will doesn’t have to be elaborate. A basic will is a few pages of plain English. The decisions are the hard part; the document itself is straightforward.
- Don’t let perfect be the enemy of good. A simple will today is better than a perfect will you keep putting off.
