What Is Inheritance? A Complete Guide to Wills, Trusts, Probate, and Estate Law in the U.S.

What happens to your money, property, and belongings when you die — and who actually controls the outcome? Most Americans have a vague sense that their assets will "go to family," but the reality is far more specific and often surprising. Inheritance in the United States is governed by a combination of federal tax law, state probate law, and the terms of wills, trusts, and beneficiary designations. Understanding how inheritance works — for both those who will leave assets and those who will receive them — is one of the most financially consequential pieces of knowledge an adult can have.

What Is Inheritance? A Complete Guide to Wills, Trusts, Probate, and Estate Law in the U.S.

What Does "Inheritance" Mean Legally in the United States?

Inheritance refers to the transfer of assets — money, real estate, personal property, investments, and other rights — from a deceased person to one or more living recipients. In American law, this transfer is governed by two overlapping systems:

Testamentary succession: Transfer based on a valid will. The person making the will (the testator) designates who receives what. Wills must generally be written, signed by the testator, and witnessed by two disinterested adults (witnesses who receive nothing under the will) to be valid. Exact requirements vary by state.

Intestate succession: Transfer dictated by state law when the deceased person has no valid will or when the will does not account for all assets. Each state has its own intestacy statute that determines the inheritance hierarchy — typically prioritising spouses, then children, then parents, then siblings, then more distant relatives.

A third mechanism — non-probate transfers — bypasses both systems entirely. Joint tenancy with right of survivorship, payable-on-death (POD) accounts, transfer-on-death (TOD) deed registrations, and life insurance policies with named beneficiaries all pass outside the will and outside probate court, directly to the named recipient upon death.

How Does the Probate Process Work?

Probate is the court-supervised process of authenticating a will (if one exists), inventorying the deceased's assets, paying debts and taxes, and distributing what remains to the beneficiaries. It is a legal proceeding, not a simple paperwork exercise.

The Probate Timeline

1. File the petition. The person named as executor (or, if no will, a personal representative) files a petition with the probate court in the county where the deceased resided.
2. Authenticate the will. The court determines whether the will is valid. If contested, this can become adversarial litigation.
3. Notify creditors. State law requires publication of a notice to creditors for a specified period (typically 3–6 months). Creditors may file claims against the estate.
4. Inventory assets. The executor catalogs all probate assets (those not passing by non-probate mechanisms), including real estate, bank accounts, investments, and personal property.
5. Pay debts and taxes. The estate pays valid creditor claims, final income taxes (Form 1040), and any estate tax due before distributing assets to beneficiaries.
6. Distribute remaining assets. Beneficiaries receive their shares as specified in the will or by intestate law.
7. Close the estate. The executor files an accounting with the court, receives discharge, and the estate is formally closed.

How long does probate take? A straightforward estate in an uncontested state may close in 6–12 months. Contested estates with real estate in multiple states, complex business interests, or disputed wills can take 3–5 years. Average probate costs run 3–7% of the gross estate value in attorney fees, executor fees, and court costs [American Bar Association, 2024].

Avoiding probate: Trusts, joint tenancy, and beneficiary designations on financial accounts allow assets to transfer immediately at death without court involvement. This is the primary motivation for trust-based estate planning.

Wills vs. Trusts: Which One Do You Need?

The will-versus-trust question is the most common starting point in estate planning discussions. The answer depends on assets, state laws, family situation, and privacy preferences.

A will is sufficient for most situations where:

• Total assets are below the state probate threshold (varies: California $184,500; Texas $75,000; Florida $75,000)
• Real estate is held jointly with right of survivorship
• All major financial accounts have named beneficiaries

A revocable living trust is preferred when:

• You own real estate in multiple states (each would require separate probate)
• You value privacy (the trust instrument is not a public record, unlike a probated will)
• You have minor children or dependents with special needs who should not receive assets outright
• Your estate is complex enough that probate costs would substantially exceed trust creation costs

An irrevocable trust is a different instrument — it removes assets from your taxable estate permanently, sacrificing control for tax and Medicaid planning benefits. Typically relevant for estates above the federal estate tax exemption ($13.61 million in 2024, reverting to approximately $7 million after the TCJA sunset in 2026).

"A will is not optional — it is the foundational document of every estate plan, whether you have a trust or not. Every person over 18 who owns anything should have a valid, current will." — Estate planning attorney James T. Morrison, member of the American College of Trust and Estate Counsel (ACTEC), Chicago, 2025.

The Federal Estate Tax: Who Actually Pays It?

The U.S. federal estate tax is the most misunderstood tax in American personal finance. Most Americans believe they will pay it; in reality, approximately 0.1% of estates pay any federal estate tax [Tax Policy Center, 2024].

The federal estate tax applies only to estates exceeding the "applicable exclusion amount": $13.61 million per individual in 2024 ($27.22 million per married couple with proper portability election). Assets below this threshold pass to heirs free of federal estate tax.

Important: this threshold is scheduled to decrease. Under the Tax Cuts and Jobs Act (TCJA) of 2017, the elevated exemption expires on December 31, 2025. Without congressional action, the exemption reverts to approximately $7 million (adjusted for inflation) in 2026. This "sunset" provision creates a planning window in 2025 for high-net-worth families to make gifts and utilize the current higher exemption before it potentially disappears.

State estate taxes: 12 states plus Washington D.C. impose their own estate taxes, with exemptions far lower than the federal threshold. Massachusetts and Oregon, for example, impose state estate taxes on estates above $2 million and $1 million respectively. The maximum state estate tax rate is 20% in Washington State.

The step-up in basis: This is the most consequential inheritance tax provision for most Americans. When you inherit an appreciated asset (a house, stocks), your tax basis for capital gains purposes is "stepped up" to the fair market value at the date of death — not the price the deceased originally paid. This means inherited assets often pass with no capital gains tax owed on decades of appreciation. A house purchased for $50,000 in 1985 and worth $600,000 at death passes to heirs with a basis of $600,000 — if they sell immediately, no capital gains tax is due.

Inheritance Tax vs. Estate Tax: A Critical Distinction

These two terms are often confused — and conflating them leads to unnecessary anxiety and poor planning decisions.

Estate tax is paid by the estate itself (from the estate's assets) before distribution to beneficiaries. It is based on the total value of assets owned at death.

Inheritance tax is paid by the beneficiary who receives the inherited assets. Only 6 states impose inheritance tax: Iowa, Kentucky, Maryland, Nebraska, New Jersey, and Pennsylvania. The tax rate and exempt relationships vary by state:

Maryland is the only state that imposes both an estate tax AND an inheritance tax.

For most beneficiaries in most states, inherited assets are received free of both state and federal inheritance or estate taxes. The step-up in basis provision means capital gains tax is also eliminated on most appreciated inherited assets.

The scenario where taxes genuinely impact inheritance is large estates (over $7–13 million), estates with significant real estate in high-tax states, or estates in the 6 inheritance-tax states passing to non-exempt relatives (e.g., siblings, nieces and nephews).

Contesting an Inheritance: When Family Members Dispute a Will

Will contests — formal legal challenges to a will's validity — represent some of the most contentious litigation in American law. They are expensive, time-consuming, and often permanently damage family relationships.

Grounds for contesting a will:

1. Lack of testamentary capacity: The testator was not of sound mind when they signed. Dementia, delusion, or mental illness can support this ground. Courts set a low bar — the testator need only have understood what they owned, who their natural heirs were, and what the will accomplished. Severe Alzheimer's may meet this threshold; mild cognitive decline typically does not.

2. Undue influence: Someone used improper pressure to override the testator's free will. Common in cases involving a caregiver, new romantic partner, or one adult child who isolated the testator from others.

3. Fraud or forgery: The will was created through deception, or the document itself is fraudulent.

4. Improper execution: The will was not signed, witnessed, or notarized as required by state law.

Who can contest a will? Only "interested parties" — those who would inherit under a prior will or by intestacy if the current will were invalidated. A distant cousin who receives nothing under intestacy typically lacks standing to contest.

What happens during a contest? The will's proponent (usually the executor) must prove validity. The contesting party bears the burden on grounds such as undue influence. Most contests settle before trial — a contested will that goes to full litigation can cost $50,000–$500,000 or more in attorney fees, consuming much of the estate.

Consider the case of the Davidson family: three adult siblings contested their father's final will, which left everything to the youngest — who had served as caregiver for the last 5 years. The estate was $1.2 million. Legal fees over 3 years of litigation reached $380,000. The eventual settlement left each sibling with approximately $270,000 — 30% less than each would have received had the original will stood and no contest been filed.

À retenir: A properly drafted will, executed with professional assistance while the testator has clear mental capacity, is the most effective will-contest prevention available.

Frequently Asked Questions About Inheritance in the United States

Do I have to pay taxes on money I inherit? For most Americans, no. Federal law does not impose income tax on inherited money or property. The step-up in basis means capital gains tax is eliminated on most appreciated assets. If you inherit in one of the 6 states with an inheritance tax and you are not an exempt relative, you may owe state inheritance tax. Consult a tax professional for your specific situation.

Can a parent disinherit a child? In most U.S. states, yes — testators have broad freedom to disinherit adult children. The exceptions are: (1) states with "forced share" provisions that guarantee spouses a minimum percentage; (2) Louisiana's "forced heirship" law that protects minor children and children with disabilities; and (3) pretermitted heir statutes that protect children born or adopted after the will was executed (unless the omission was intentional).

What happens if my spouse dies without a will in a community property state? Community property states (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, Wisconsin) treat most assets acquired during marriage as equally owned by both spouses. If your spouse dies without a will, their 50% share of community property typically passes to you (surviving spouse) under intestate law, while separate property follows the state's intestacy hierarchy.

How do I handle the inheritance of a retirement account (IRA, 401(k))? Inherited retirement accounts are governed by the beneficiary designation on file with the financial institution — not by the will or trust. Under the SECURE Act 2.0 (effective 2024), most non-spouse beneficiaries must fully withdraw an inherited IRA within 10 years of the original owner's death. Inherited amounts are subject to income tax as they are withdrawn. Spouses have additional options including treating the inherited IRA as their own.

Can I refuse an inheritance? Yes. A formal "disclaimer" (refusal) of an inheritance must be in writing, filed within 9 months of the decedent's death, and irrevocable. Common reasons to disclaim: the estate has significant debts (you do not want to inherit a liability-heavy property); Medicaid planning (disclaiming allows the asset to pass to a spouse who needs it while preserving Medicaid eligibility); tax planning (disclaiming to a lower-bracket beneficiary).

Digital Assets and Modern Inheritance: A Growing Challenge

The average American adult in 2026 owns hundreds of digital accounts, many with monetary value: cryptocurrency wallets, stock brokerage accounts, online businesses, domain names, social media accounts with monetization enabled, and digital content libraries. Traditional estate planning documents rarely address these assets specifically — and the results are often catastrophic.

The access problem: Digital assets are protected by passwords, two-factor authentication (2FA), and encryption. Heirs who cannot access an account typically cannot prove ownership or recover funds. An estimated $50 billion in Bitcoin is permanently inaccessible due to lost credentials from deceased holders [Chainalysis, 2023].

What to do:

1. Create a secure digital asset inventory: all usernames, account types, and instructions for access (do not store passwords in the will, which becomes public record).
2. Designate a "digital executor" — most states now allow this under the Revised Uniform Fiduciary Access to Digital Assets Act (RUFADAA), adopted in 47 states and D.C.
3. Use a reputable password manager with an emergency access feature (1Password, Bitwarden, LastPass all offer mechanisms to grant heir access after death).
4. Check each platform's legacy options: Meta/Facebook has a Legacy Contact feature; Google has Inactive Account Manager; Apple now has Digital Legacy contacts.

Cryptocurrency-specific considerations: Hardware wallets and seed phrases must be physically secured and their location communicated to a trusted heir. Leaving $100,000 in Bitcoin on a hardware wallet with no heir knowledge of its existence is equivalent to burning the money. Store seed phrases in a fireproof safe, safety deposit box, or with an attorney under attorney-client privilege.

Social media and online businesses: Some platforms allow account memorialization (Facebook, Instagram) rather than deletion. If a deceased person had a significant online business (Etsy shop, YouTube channel, Amazon seller account), revenue may continue flowing post-death — and the estate has the right to those proceeds. Identify these accounts explicitly in estate planning documents.

Planning Your Own Estate: A Practical Checklist

Estate planning feels abstract until someone close to you dies without one — and then it feels urgent. Most adults procrastinate because it forces confrontation with mortality; the practical steps, however, are surprisingly manageable.

Estate Planning Checklist for American Adults

Documents to create (in order of priority):

Steps to take now:

1. Review all beneficiary designations on 401(k), IRA, life insurance, and bank accounts — update for any marriage, divorce, birth, or death in the family.
2. Determine whether property is titled correctly (joint tenancy vs. tenancy in common matters enormously at death).
3. If you have minor children, choose and document a guardian in your will.
4. Communicate your wishes to the people who need to know: executor, healthcare proxy, digital executor.
5. Store documents somewhere accessible — a fireproof home safe, bank safety deposit box (ensure someone else has access), or with your attorney.
6. Review the estate plan every 3–5 years or after any major life change.

Most Americans can accomplish a complete basic estate plan (will, powers of attorney, advance directive, beneficiary review) in 2–4 hours with an attorney, for under $1,000. The percentage of Americans who have done so remains, as noted, below 33%.
