Do I Need an Estate Plan? (Yes, and Here Is Why)

Yes. If you are an adult with any assets, a bank account, a home, a retirement plan, or people who depend on you, you need an estate plan. The question is not whether you have one, but whether you have one you wrote or one your state wrote for you. Everyone who dies with property has an estate plan by default: the intestacy laws of their state, which decide who inherits, in what shares, and who raises minor children, without regard to your wishes. A deliberate plan replaces that default with your own decisions, minimizes taxes and court involvement, names the people you trust to act for you, and protects you while you are alive but unable to act. At a minimum that means a will, financial and healthcare powers of attorney, and current beneficiary designations; for families with greater wealth, it means trusts and tax planning layered on top.

What happens if I do not have an estate plan?

This is the most useful way to see why a plan matters: look at what the state does in your absence.

If you die without a will, you die "intestate," and state law distributes your probate assets according to a fixed statutory formula. That formula may not match your intentions. Depending on the state and your family structure, a surviving spouse might share an inheritance with your children, parents, or siblings, and unmarried partners, stepchildren, friends, and charities typically receive nothing. If you have minor children and both parents are gone, a court, not you, decides who becomes their guardian.

Beyond who inherits, the absence of a plan creates process problems. Assets pass through probate, a public court proceeding that can be slow and costly. No one has clear legal authority to manage your finances or make medical decisions if you become incapacitated, which often forces your family into a court guardianship or conservatorship. A plan exists to prevent all of this.

What are the core documents everyone needs?

A complete foundational plan is built from a short list of documents. Each does a specific job, and the set works together. We cover the full list in the estate planning checklist; the essentials are these.

• A will directs who receives your probate assets, names an executor to carry out your wishes, and, critically for parents, nominates guardians for minor children.
• A revocable living trust can hold your assets so they pass to heirs without probate, privately and often faster, and provides for management if you become incapacitated.
• A financial power of attorney authorizes someone you trust to handle money matters if you cannot.
• A healthcare power of attorney and a living will or advance directive name a medical decision-maker and state your wishes for care.
• Beneficiary designations on retirement accounts, life insurance, and payable-on-death accounts control those assets directly and override your will, so they must be kept current.

That last point causes more problems than almost any other. Beneficiary designations pass property outside your will, so a stale designation, an ex-spouse never removed, a predeceased beneficiary, a form never updated after a child was born, can redirect significant assets regardless of what your will says.

Do beneficiary designations override my will?

Yes, and this surprises many people. Retirement accounts, life insurance, annuities, and accounts titled "transfer on death" or "payable on death" pass to the named beneficiary by contract, outside the will and outside probate. If your will leaves everything to your spouse but your 401(k) still names a sibling, the sibling generally receives the 401(k). Reviewing beneficiary designations is one of the highest-value, lowest-cost steps in estate planning, and it should happen after every major life event.

When do I need more than the basics?

The foundational documents serve almost everyone. Greater wealth and complexity call for additional planning, primarily to manage estate tax, control how and when heirs receive assets, and protect the family.

The federal estate and gift tax exemption is $15,000,000 per person, or $30,000,000 for a married couple, in 2026 under the One Big Beautiful Bill Act. Estates below that face no federal estate tax, but several states impose their own estate or inheritance taxes at far lower thresholds, so state exposure can exist even when federal tax does not. Above the exemption, the federal rate reaches 40%, which makes lifetime planning valuable. Families at these levels often use irrevocable trusts such as GRATs, SLATs, and dynasty trusts to transfer wealth efficiently, as we describe in the trusts wealthy families actually use. Trusts also serve non-tax goals: providing for a child with a disability, protecting an inheritance from a beneficiary's creditors or divorce, supporting a surviving spouse while preserving assets for children, or setting conditions on distributions to young heirs.

Certain situations deserve specific attention. If you own a business, have a blended family, have no children, or have a dependent with special needs, the standard documents are rarely enough. For the childless case in particular, see estate planning without children.

A worked example: the cost of the default

The following is a hypothetical illustration. A married Wisconsin resident with two young children and $3,000,000 in assets dies without any estate plan.

Because there is no will, state intestacy law determines distribution, and because the children are minors, their share must be managed under court supervision until they reach adulthood, when they receive it outright regardless of readiness. With no named guardian, a judge selects who raises the children from among competing relatives. With no powers of attorney in place before death, any prior period of incapacity would have required a court-appointed guardian to manage finances and healthcare. A modest set of documents, a will with a guardian nomination, a revocable trust to manage the children's inheritance until a chosen age, and powers of attorney, would have replaced every one of those court processes with the parents' own decisions. The example is hypothetical, but the contrast is the lesson: planning is far cheaper and kinder than its absence.

Frequently asked questions

Do I need an estate plan if I am not wealthy?Yes. Estate planning is about control and protection, not just taxes. Even a modest estate benefits from a will, powers of attorney, and current beneficiary designations, which spare your family court proceedings and uncertainty.

Is a will enough, or do I need a trust too?A will is the minimum, but a revocable living trust adds probate avoidance, privacy, and management during incapacity. Whether you need one depends on your assets, your state's probate process, and your goals. Many families use both.

What happens to my assets if I die without a will?They pass under your state's intestacy law, which sets fixed shares among relatives and may exclude unmarried partners, stepchildren, and charities entirely. A court also decides guardianship of minor children. The outcome may not reflect your wishes.

How often should I update my estate plan?Review it after any major life event, marriage, divorce, birth, death, a large change in wealth, or a move to another state, and otherwise every three to five years. Beneficiary designations should be checked most frequently.

Do my retirement accounts pass through my will?No. Retirement accounts and life insurance pass by beneficiary designation, outside your will. Keeping those designations current is essential, because they override whatever your will says.
