Inheritance in American Law: The Legal Framework of Wills, Legal Inheritance, Probate Process, and Tax Aspects in the USA

How does inheritance work in American law? This comprehensive guide explains wills, legal heirship, the probate process, trust structures, spouse's rights, federal estate tax, and inheritance rules for foreigners' assets in the US.

In American law, when it comes to inheritance, the first and most important observation is this: U.S. inheritance law is not a unified system regulated within a single national civil code. The distribution of inheritance, the validity of wills, the legal order of heirs, the probate procedure, spouse protection, and minor estate procedures are largely state law . In contrast, the federal level is more estate tax . While New York courts explicitly state that Surrogate's Court handles matters relating to the deceased's estate, such as the probate of wills and the administration of the estate, California courts also state that post-mortem estate disputes fall within the scope of probate. (nycourts.gov)

Therefore, any general information given under the heading "Inheritance Law in America" ​​should inevitably be read with the caveat that "it may vary between states." Nevertheless, there are some fundamental axes common to the US system: testate succession applies if a person has left a will, and intestate succession applies if no will has been left ; some assets go through a probate court while others go directly to the beneficiary or surviving spouse; the estate's debts and taxes are primarily paid from within the estate; and the surviving spouse cannot be completely excluded in many states. Therefore, it is necessary to address the subject in a way that explains the common structure without denying state differences. ( nycourts.gov )

The basic structure of inheritance law in the United States

In the United States, three main concepts form the backbone of inheritance law: will, intestacy , and probate. If a person dies and leaves behind a valid will, as a rule, the wishes contained in that will are asserted in probate court and its validity is examined. New York CourtHelp clearly explains that if a will exists, it is presented to the court during the probate process, and the executor designated in the will is authorized to manage the estate. (ww2.nycourts.gov)

If a person dies without making a will, the rules of intestacy of the relevant state apply, rather than their personal wishes . New York courts explicitly state that in the case of death without a will, the estate is distributed to legal heirs in accordance with EPTL 4-1.1. California courts similarly specify who takes priority and who acts as administrator in the absence of a will; the general order is the surviving spouse or partner, followed by children, grandchildren, parents, and siblings. This structure demonstrates that legal inheritance in the US also operates on a state-by-state basis, but according to specific sets of rules. ( nycourts.gov )

In simple terms, probate is the process of collecting the estate after death under court supervision, settling debts, and distributing the remaining assets to heirs or beneficiaries of the will. California courts define probate as the general framework concerning the assets, debts, and distribution process after a person's death. New York courts also differentiate between probate and administration, stating that probate is applied if a will exists, and administration if there is no will. (selfhelp.courts.ca.gov)

What happens if there is a will?

In the United States, a valid will is central to probate planning. However, a will alone does not automatically have legal effect; in most states, it must be presented to a court after death to have its validity confirmed. The New York Surrogate's Court defines the probate process as the procedure that proves the presented document is indeed the deceased's last will and testament, authorizing the executor. This demonstrates that a will is not merely a private document, but a declaration of intent subject to judicial review after death. (ww2.nycourts.gov)

In the United States, a person can, as a rule, determine through a will who will inherit their assets, in what proportions, and under what conditions. However, this freedom is not unlimited. Many states elective shares , in favor of the surviving spouse. Cornell LII defines the elective share as a mechanism that prevents a spouse from being completely excluded from the inheritance through a will and usually grants them a choice over a specific portion of the probate estate. Therefore, the outcome of "I can completely exclude everyone from the inheritance through a will in the US" is not possible in the same way in every state. (law.cornell.edu)

Another practical point of importance here is that a will does not always control non-probate assets. Life insurance beneficiaries, payable-on-death accounts, some forms of common ownership, and assets included in living trusts often pass directly by contract or ownership structure. Cornell LII states that non-probate assets can include life insurance, pensions, common ownership, and structures like living trusts. California courts also explicitly state that payable-on-death accounts can pass to the beneficiary without probate. (law.cornell.edu)

If there is no will, how is the inheritance divided?

In the US, if there is no will, the division of assets intestate succession rules of the respective state. New York courts clearly state this under the heading "When There Is No Will," indicating that the assets will be divided according to legal distribution rules. California courts, when explaining the order of priority in cases of death without a will, state that the surviving spouse and children generally take the first place. (nycourts.gov)

However, there is a crucial point here: generalizations such as "the spouse takes everything" or "children automatically divide equally" are not true for every state and every type of estate. The spouse's assets, the presence of children from previous marriages, whether the property is community property or separate property, and which assets are included in the estate all directly affect the outcome. The distribution logic in places with strong community property traditions, like Texas, may differ from that in common-law states like New York. TexasLawHelp materials and IRS Publication 555 clearly demonstrate that the distinction between community property and separate property has consequences after death. (TexasLawHelp.org)

Therefore, in U.S. death without a will case, the first thing to do is to classify the assets not just by "what is there?", but also by "under which state law and under which property regime?". The order of distribution among spouse, children, children from previous marriages, parents, and siblings depends on the technical provisions of state laws. New York CourtHelp's direct reference to EPTL 4-1.1 also confirms this technical nature. (nycourts.gov)

Which goods are included in Probate and which are not?

One of the most important distinctions in US inheritance practice probate and nonprobate assets . Probate assets are, as a rule, items of the estate held in the deceased's own name and for which the beneficiary has not been otherwise determined. Nonprobate assets, on the other hand, often pass directly to another person without waiting for court proceedings, based on the existing contract or ownership structure. Cornell LII clearly emphasizes this distinction. (law.cornell.edu)

California courts provide highly instructive examples on this matter. They explain that payable-on-death accounts can pass directly without probate if the correct beneficiary is designated; and that living trusts can help transfer significant assets, such as homes, to designated individuals without going through probate. California courts even highlight the function of living trusts in reducing probate time and costs. This clearly demonstrates why inheritance planning in the U.S. should not be seen as limited solely to wills. (selfhelp.courts.ca.gov)

Therefore, in the U.S., good inheritance planning often begins with the question: “Will this property go through a probate court after death, or will it be transferred through another means?” This is because a will, a trust, a POD account, common property, and beneficiary designation do not serve the same function. The distribution logic for property subject to probate differs from that of property not subject to probate; in some states, non-probate assets may also be particularly important in terms of the spouse's elective share rights. (law.cornell.edu)

What do the executor, administrator, and estate representative do?

In U.S. probate law, an estate has a "representative." If there is a will, this is often an executor; if there is no will, and the court an administrator . California courts, under the heading "estate representative," explain that if there is a will, the executor is appointed; otherwise, the court appoints a representative according to the legal order of priority. The surviving spouse or children are usually at the top of the list; however, the final decision, especially in disputes, is made by the court. (selfhelp.courts.ca.gov)

The primary duties of this administrator include collecting estate assets, establishing a balance of assets and liabilities, fulfilling valid claims, reporting to the court, and ultimately completing the distribution. The New York Administration Packet and Surrogate's Court statements emphasize the administrator's authority to collect assets, settle debts, and distribute shares to rightful heirs. A significant portion of inheritance disputes in the U.S. revolve around who this administrator should be or how they should perform their duties. (nycourts.gov)

Estate debts and creditors

In the United States, inheritance doesn't operate on the principle of "the deceased's debts are forgiven, and the heirs simply inherit the property." As a rule, the estate is administered first; any outstanding debts and expenses of the estate are paid from within the estate, and then distribution to the heirs takes place. California court creditor's claim material clearly indicates that creditors can file claims against the estate and that proper submission of claims is crucial. Furthermore, the probate terms page also emphasizes that debts and liabilities will be met from the estate. (selfhelp.courts.ca.gov)

Therefore, the practical risk for heirs is not just the share ratio; it is the estate's debt burden. Especially in cases with high credit debt, tax debt, healthcare expenses, or business liabilities, a “nominally large estate” can actually become a limited or problematic one. Estate inventory and creditor process are therefore of paramount importance in US probate practice. (selfhelp.courts.ca.gov)

Why are community property states important?

In the United States, marital property regimes are very important in inheritance distribution. According to IRS Publication 555, community property states include Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin. The same IRS source states that community property law can affect not only income tax calculations but also the tax basis of inherited property in the event of a spouse's death. (irs.gov)

Therefore, the same family structure can produce different results in New York than in California or Texas. In particular, the surviving spouse's position on community property is not the same as their position on separate property. In states with community property regimes, simply asking "Is there a will?" is insufficient when conducting inheritance analysis; it is also necessary to examine whether the property was part of the community property regime during the marriage or whether it is separate property. (irs.gov)

Small estates and simplified procedures

Not every estate in the U.S. undergoes a full probate process. States may offer faster procedures for small or low-value estates. California courts explicitly state that simplified “summary succession” and small estate affidavit processes exist for properties below certain thresholds; however, full probate typically 9 to 18 months . In California, for example, the threshold for some simplified personal property transfers on or after April 1, 2025, $208,850 . (selfhelp.courts.ca.gov)

New York also has similar small estate procedures. New York CourtHelp states that in some estate cases with personal assets $50,000, the small estate, or voluntary administration, procedure can be applied. These thresholds vary from state to state; therefore, even for small estate cases, one cannot say "this is the standard figure in the US." (nycourts.gov)

Federal tax aspects: estate tax, portability, and filing threshold

The prominent issue at the federal level of U.S. inheritance law is not a classic beneficiary-side “inheritance tax”; rather, it is essentially a federal estate tax regime based on the transfer of the estate. The IRS’s explanations of the estate tax and Form 706/706-NA reveal that the tax is primarily based on the transfer of the deceased’s taxable estate . The IRS has also stated that the filing threshold is $15,000,000 for 2026 and $13,990,000 for 2025. ( irs.gov )

Another important federal institution regarding surviving spouses is portability . The IRS states that Form 706 must be filed in a timely manner for the unused exception of the deceased spouse to be transferred to the surviving spouse , generally within 9 months of the date of death, with an additional 6 months requested if necessary . This is an extremely critical tool in inheritance planning, especially for high-net-worth spouses. ( irs.gov )

Inheritance of foreigners' assets in the United States

Individuals who do not reside in the United States or are not US citizens may also own real estate, shares, accounts, or other assets in the US. In this case, inheritance matters may involve not only state probate law but also federal estate tax. According to the IRS , for a non-resident (not a citizen) whose total US-situated assets at the time of death exceed $60,000 under certain conditions, Form 706-NA becomes relevant. The IRS explicitly states that there is no inflation indexation at this threshold. ( irs.gov )

This section is particularly important for individuals from Turkey who hold real estate or investment accounts in the United States. This is because simply being a resident of Turkey or a Turkish citizen does not mean that assets in the US will be unaffected by US law after death. Rather, the location of the property, the nature of the asset, and the individual's status are all considered together. In such cases, both the state law where the estate is located and the IRS estate tax regime often apply simultaneously (irs.gov)

Conclusion

In American law, inheritance is not a single, uniform system; it is a multi-layered area where state law and federal tax law work together. Probate and executor (if a will exists); intestacy and administrator (if no will exists); property subject to probate and property transferred outside of probate through trusts, PODs, or similar arrangements; protection of the surviving spouse in the context of elective shares and community property; minor estate procedures; debts and creditor claims; federal estate tax and portability are all part of this system. (ww2.nycourts.gov)

Therefore, in US inheritance law, the correct question is not "How is an inheritance divided in America?" but rather "In which state did the deceased live, where were the assets located, was there a will, which assets are subject to probate, what is the status of the surviving spouse and children, and is the federal tax threshold exceeded?" In US inheritance cases, the outcome is often not determined by a single general statement, but rather by analyzing state law, marital property regimes, asset structure, and the tax implications together.
