If you own or plan to buy property in the US, understanding USA inheritance laws is essential to protect your assets and make sure your wishes are carried out across state lines.
Buying a home in the United States is exciting, but the legal side can quickly become complicated when you start thinking about what happens to that property later. US inheritance laws are not handled at a national level in the same way as in the UK. Instead, each state sets its own rules, which means your estate planning needs to be tailored to where your property is located.

How USA inheritance laws work in practice
In the US, inheritance laws determine who receives your assets after death and how those assets are divided. They also set out which relatives may have a legal claim on your estate, even if they are not named in your will.
The key point you need to understand is that states follow one of two systems โ community property or common law. This distinction directly affects how your property is treated, particularly if you own with a spouse.
Community property states and what they mean for you
If your property is in a community property state, the law assumes that most assets acquired during your marriage are jointly owned. This includes income, property purchased during the marriage and any assets that have been merged into shared ownership.
The vast majority of US states โ including popular overseas buyer locations such as Florida and New York โ follow common law rules.
The main community property states include California, Texas, Arizona and Nevada, along with others such as Washington, Idaho, New Mexico, Louisiana and Wisconsin.
In practical terms, this means:
- You and your spouse each own 50% of marital assets
- Your spouse is automatically entitled to their half
- You can decide what happens to your share through your will
However, not everything is automatically shared. Assets may still be treated as separate property if they were:
- Owned before marriage
- Received as a gift or inheritance
- Protected by a legal agreement such as a prenuptial contract
If you are structuring ownership of a US property, this distinction matters. For example, buying in one name only in a community property state does not automatically remove a spouseโs entitlement.
Common law states and ownership rules
In common law states, ownership is far more literal. The name on the title or the source of funds usually determines who owns an asset.
This creates a very different outcome:
- There is no automatic 50/50 split
- Property belongs to the person named on the deed
- A spouse does not automatically inherit half
That said, most states still protect a surviving spouse to some extent. Even if a will leaves them out, they can often claim a fixed share of the estate through the courts.
For overseas buyers, this makes ownership structure critical. If you are purchasing with a partner or family member, how the property is titled can directly affect inheritance outcomes.
What happens to your estate after divorce?
Divorce adds another layer of complexity. Some states automatically revoke gifts to an ex-spouse in a will, while others do not.
The safest approach is simple: if your circumstances change, update your will. Relying on default state rules can lead to outcomes you did not intend.
Do children and grandchildren automatically inherit?
Unlike in some countries, children in the US do not always have an automatic right to inherit. However, there are safeguards in place.
For example, if a child is unintentionally left out of a will โ such as being born after it was written โ courts may step in and award them a share.
Grandchildren generally do not have a direct right to inherit unless specific conditions apply, such as their parent having already passed away.
This means that if you want to provide for children or grandchildren, you need to be explicit in your will.
Why making a US will matters
Relying on a UK will alone is rarely enough when you own property in the US. The differences between state laws, combined with local probate processes, can create delays and unexpected outcomes.
Putting a US-compliant will in place allows you to:
- Clearly set out how your property should be distributed
- Reduce the risk of disputes
- Speed up the legal process for your family
For most overseas buyers, working with a US-based estate planning lawyer is not just helpful but essential, particularly as state laws and federal tax rules continue to evolve.
Final thoughts for overseas buyers
US inheritance law is not something to leave until later. The way your property is owned today will shape what happens to it in the future. With tax rules and thresholds evolving in 2026 and beyond, taking advice early is more important than ever. By understanding whether your state follows community property or common law rules and putting the right legal structure in place, you can avoid complications for your family later on.
Taking advice before you buy, rather than after, will give you far more control over the outcome.
FAQ about USA inheritance laws
Inheritance rules depend on the state where the property is located. States follow either community property rules, where marital assets are split equally, or common law rules, where ownership depends on title and contribution. In most cases, spouses have legal protection and can claim part of the estate even if excluded from a will.
There is no federal inheritance tax for beneficiaries, but estate tax may apply to the deceasedโs estate. As of 2026, the federal estate tax exemption stands at $15 million per individual. Some states also apply their own estate or inheritance taxes at lower thresholds, so the rules depend on where the property is located. It is worth taking professional advice, as thresholds and tax rules can change.
Yes, if you receive more than $100,000 from a foreign estate, you are typically required to report it to the IRS using Form 3520. This is a reporting requirement rather than a tax in most cases, but failing to declare it can lead to penalties. Thresholds and reporting rules can change, so it is worth confirming the latest IRS guidance for the relevant tax year.
