Inheritance Law in the United States: Heir Guide

Inheritance Law in the United States: Heir Guide

Inheritance law in the United States is not one single nationwide code: it is a mix of state probate law, federal tax rules, court procedures, and the terms of the deceased person’s will or trust. For heirs—especially foreign heirs—the key questions are usually: who has the legal right to inherit, whether probate is required, who can act for the estate, what documents are needed, and whether U.S. estate tax filings may apply.

What “inheritance” means in U.S. law

In everyday speech, “inheritance” can mean any property received after someone dies. Legally, the term is narrower. Cornell’s Wex legal dictionary explains that inheritance refers to property that passes to an heir through intestacy when a person dies without a valid will (Cornell Wex). If there is a valid will, the people receiving assets are often called beneficiaries or devisees rather than heirs, although many families use the words interchangeably.

This distinction matters because the path to receiving property can be different. If there is a will, the probate court generally looks to the will to identify beneficiaries and the person nominated to administer the estate. If there is no valid will, state intestacy law determines who inherits. The result can depend on family relationships, marital status, and the state where probate is opened.

Probate in the United States: the basic process

Probate in the United States is the court-supervised process for proving a will, appointing someone to administer the estate, identifying assets and debts, and distributing property to the proper heirs or beneficiaries. The person appointed may be called an executor, administrator, or personal representative, depending on the situation and the state.

Although procedures vary by state, estate administration in the USA usually involves these practical steps:

  • locating the original will, if one exists;
  • filing a probate petition in the appropriate court;
  • obtaining court authority, often through documents such as letters testamentary or letters of administration;
  • identifying estate assets, debts, and possible creditors;
  • preparing accountings or reports if required;
  • paying valid expenses and taxes; and
  • distributing remaining assets to those entitled to receive them.

For more on the court authority an executor may need, see this guide to letters testamentary for foreign heirs. If you are waiting for a distribution, it is also useful to understand what an estate accounting should show; this probate accounting checklist for foreign heirs explains common items to review.

Inheritance rights in the USA: will, intestacy, and beneficiary designations

Inheritance rights in the USA depend first on how the asset is owned and whether it passes through probate. Some assets may be controlled by a will or intestacy law. Other assets may pass by beneficiary designation, joint ownership, or trust terms. That is why an heir should not assume that every asset mentioned by a family member will automatically be distributed through the probate court.

If there is a dispute, the probate court may need to decide whether a will is valid, whether a person has standing to object, or whether the estate representative is properly performing duties. Foreign heirs should pay close attention to notices from the court or estate representative, because missing a response deadline can make it harder to protect rights later. The exact procedure depends on the state and the court handling the estate.

Foreign heirs and U.S. inheritance: practical issues

Foreign heirs US inheritance cases often move more slowly because documents must cross borders. A foreign heir may need to prove identity, relationship to the deceased, address, tax status, or authority to act for another person. Documents issued outside the United States may need authentication or translation before a U.S. court, bank, title company, or estate lawyer will accept them.

Common document issues include birth certificates, marriage certificates, death certificates, powers of attorney, and proof of name changes. If your probate documents must be used internationally, this guide to apostilles for probate documents explains the role of authentication in cross-border estates.

Foreign heirs should also be cautious about unclaimed assets. Sometimes an heir is named in a will but cannot be located, or estate funds remain undistributed because contact information is outdated. If you believe a U.S. inheritance may exist but you have not been contacted, see this unclaimed inheritance guide for foreign heirs.

Federal estate tax and inherited property basis

U.S. tax treatment is a major part of estate planning and administration, but it is often misunderstood. The federal estate tax, when applicable, is generally an estate-level issue rather than a simple tax on each heir’s receipt of property. For decedents dying in 2026, the IRS basic exclusion amount for federal estate tax is $15,000,000 (IRS Form 706 instructions). For decedents dying in 2026, Form 706 must be filed if the gross estate plus adjusted taxable gifts and specific exemption is more than $15,000,000 (IRS Form 706 instructions).

Heirs should also understand income tax basis. The IRS states that the basis of property inherited from a decedent is generally the fair market value on the date of the individual’s death (IRS Publication 559). This can matter later if the heir sells inherited real estate, securities, or other property. The IRS also notes that in 2015, Congress passed a law requiring, in certain circumstances, that the recipient’s basis in certain inherited property must be consistent with the value finally determined for federal estate tax purposes (IRS FAQs on gifts and inheritances).

Can an heir refuse an inheritance?

Sometimes an heir may not want to receive property, especially if the asset is difficult to manage, located far away, or creates tax or family complications. U.S. law recognizes disclaimers or renunciations in certain contexts, but the rules are technical and timing can be critical.

One specific federal rule provides that a person 18 years of age or older may renounce or disclaim an inheritance of trust or restricted land or trust personalty through intestate succession or devise by filing a signed and acknowledged declaration before the probate decisionmaker prior to the final probate order (25 U.S.C. § 2206). Because disclaimers can affect tax, creditor, and family rights, heirs should get advice before signing anything.

What heirs should do next

If you are dealing with US inheritance law from abroad, start by identifying the state where the deceased lived, whether a probate case has been opened, and who has legal authority to act for the estate. Request copies of the will, probate petition, court appointment documents, inventory, and any accounting that has been filed or circulated.

Do not rely only on informal family updates. Inheritance law in the United States is document-driven, and the person who controls estate information may not always explain every option. A foreign heir should keep copies of all correspondence, confirm deadlines in writing, and seek state-specific legal and tax guidance before selling, disclaiming, or transferring inherited property.
