Yes. A prenup does not need to describe a specific inheritance to protect it. It can state in advance that any inheritance either of you receives, before or during the marriage, stays separate property, which covers money or property you have not received yet.
Key Takeaways
- Yes, a prenup can protect an inheritance you have not received yet. It works by setting a rule now, that any future inheritance stays separate, rather than trying to describe a specific asset that does not exist yet.
- In most states, inheritance is already treated as separate property by default, even without a prenup. The real risk is not the default rule. It is what happens to that money after you receive it.
- The moment inherited money gets deposited into a joint account, used for a joint purchase, or mixed with marital funds, part of it can become marital property, the same trap that catches premarital assets and mortgage payments.
- A prenup can go further than the default rule by requiring the inheriting spouse to keep it in a separate account and by defining what happens to any growth or income the inherited asset produces during the marriage.
- Because the inheritance does not exist yet, this only works if the clause is written broadly enough to cover whatever you eventually receive, from whichever relative, in whatever form it arrives.
Yes, You Can Protect Something You Don’t Have Yet
The instinct behind this question makes sense. A prenup feels like a document that lists what you have and decides who gets what. If you have not received an inheritance yet, there is nothing to list, so it seems like there is nothing to protect.
That instinct is wrong, and it is wrong in a useful way. A prenup does not have to describe a specific dollar amount or a specific asset. It can instead write a rule that applies to a category of future events. “Any inheritance either of us receives, at any point, from any source, remains that person’s separate property” is a complete, enforceable instruction, and it works exactly the same whether the inheritance arrives next year or twenty years into the marriage. You are not protecting an asset. You are protecting a future outcome.
Inheritance Is Already Separate Property, Mostly
Here is what makes this question more interesting than it first appears. In most states, an inheritance is already treated as separate property by default, even for couples with no prenup at all. Unlike income earned during the marriage, money or property that arrives to one spouse specifically, through a will or by intestate succession, generally is not divided the way a paycheck or a joint investment account would be.
So if the default rule already protects inheritance, what is a prenup actually adding? The default rule protects the inheritance in theory. It does nothing to protect the behavior that happens after you receive it, and that behavior is where inheritances actually get divided in a divorce.
Where the Real Risk Is: Commingling After You Receive It
This is the same signature problem that shows up with premarital assets and houses owned before marriage, just with a different starting asset. Once you are married, the income either of you earns is marital property. Inheritance is the one major exception to that rule, treated as separate from the moment it lands, but only for as long as it stays separate in practice.
Picture a spouse who inherits $150,000 from a parent partway through the marriage. If that money goes into a joint checking account the couple uses for household expenses, it stops being cleanly traceable as separate property within a matter of months. If it gets used as part of a down payment on a house titled to both spouses, part of that $150,000 has now funded a jointly-owned asset, and untangling how much of the house is “really” separate becomes a fact-intensive argument years later, at exactly the moment neither spouse wants to be reconstructing bank statements from a decade ago.
None of this requires anyone to do anything wrong or unusual. Depositing an inheritance into the household account is the normal, well-meaning thing most people do. It is also the exact behavior that erodes the separate-property protection the law gives inheritance in the first place.
What a Forward-Looking Inheritance Clause Should Say
A clause written to protect a future inheritance needs to do more than repeat the default rule. It should define inheritance broadly, covering cash, real property, business interests, or anything else that might arrive from a will, a trust distribution, or intestate succession, so the clause does not accidentally miss the specific form an inheritance actually takes when it shows up.
It should state plainly that any such inheritance remains the separate property of the receiving spouse regardless of timing, and it should require that the money or asset be kept in an account or under a title held solely in that spouse’s name, precisely to prevent the commingling problem described above. A well-drafted clause also addresses what happens to any growth, income, or appreciation the inherited asset produces during the marriage, since states differ on whether that growth stays separate too, and a couple can decide the answer themselves instead of leaving it to a court later.
Thinking about a prenup?
Talk to an attorney before you decide. A 30-minute consultation is $150 — credited toward your agreement if you move forward.
Schedule a Consultation →Some couples add a reimbursement provision as a backstop: if inherited funds do end up contributing to a jointly-titled purchase, the inheriting spouse is repaid that contribution first, before whatever remains gets divided under the marriage’s normal rules. That single sentence can save years of argument if life does not go exactly as planned.
How This Fits Into Your Prenup
This clause does not need to be complicated, but it does need to be broad and specific at the same time, broad enough to cover an inheritance that has not happened yet, specific enough to actually prevent the commingling that erodes the default protection. It fits alongside the same thinking that protects any premarital asset from quietly becoming shared property, and it works the same way when one spouse already owns a house going into the marriage and keeps paying it down with income earned after the wedding.
The document does the planning. The discipline after you actually receive the inheritance, keeping it separate in practice and not just on paper, is on you, and a good attorney will tell you plainly what that discipline needs to look like for your specific situation. That is also what makes a prenup enforceable in court when the moment eventually comes to rely on it: full disclosure, clear terms, and no ambiguity about what was agreed to.

Frequently Asked Questions
Can a prenup protect an inheritance I haven’t received yet?
Yes. The clause does not need to describe a specific inheritance. It can state that any inheritance either spouse receives, at any point during the marriage, stays that spouse’s separate property, which covers inheritances that have not happened yet.
Is inheritance automatically separate property without a prenup?
In most states, yes, inheritance is treated as separate property by default. The bigger risk is not the default rule itself. It is what happens to the inheritance after it is received, since commingling it with marital funds can erode that protection over time.
What happens if I deposit an inheritance into a joint account?
Depositing inherited money into a joint account used for household expenses is one of the most common ways separate property becomes difficult to trace as separate, and part of it can end up treated as marital property in a divorce. Keeping it in an account titled solely to you is what actually protects it in practice.
Does the growth or income from an inherited asset stay separate too?
It depends on the state and on how the prenup is written. A well-drafted clause specifies what happens to appreciation, dividends, or income the inherited asset produces during the marriage, rather than leaving that question to a court’s default rule.
What if my inheritance comes as property, like a house, instead of cash?
A forward-looking clause should define inheritance broadly enough to cover real property, business interests, or any other form an inheritance might take, not just cash, so the protection applies no matter what actually arrives.
Do I need to update the prenup once I actually receive the inheritance?
Not necessarily, if the clause was written broadly enough to cover it from the start. Some couples choose to document the specific inheritance once it arrives for added clarity, but a properly drafted forward-looking clause should already cover it.
