The short answer: in Missouri, your inheritance is generally yours to keep — but only if you handled it the right way during the marriage.
Inheritance is one of the most commonly misunderstood assets in a divorce. Most people assume that because the money came from a parent or grandparent, it’s automatically off-limits. That’s true on day one. What happens after that depends entirely on what you did with it.
The Default Rule: Inheritance Is Separate Property
Missouri is an equitable distribution state, which means courts divide marital property fairly — not necessarily equally — at divorce. But before anything gets divided, every asset has to be classified as either marital or separate (also called non-marital) property.
Under § 452.330 RSMo, separate property includes:
- Property either spouse owned before the marriage
- Property acquired during the marriage by gift, bequest, devise, or descent (in plain English: gifts and inheritance)
- Property acquired in exchange for separate property
- Property excluded by a valid agreement (like a prenup or postnup)
Inheritance falls squarely in this category. If your aunt left you $80,000, that money starts out as 100% yours. Your spouse has no claim to it — at least not yet.
How Inheritance Becomes Marital Property: Commingling
This is where most people lose their inheritance without realizing it. The legal term is commingling, and it means mixing separate property with marital property to the point where the two can no longer be reasonably separated.
Once that happens, the inheritance loses its separate character and gets thrown into the marital pot for division.
Common Ways Inheritance Gets Commingled
Depositing it into a joint account. This is the single most frequent mistake. The moment you put inheritance money into an account titled jointly with your spouse — and certainly once you both start using that money for household expenses — it begins to lose its separate identity.
Using it on the marital home. If you used inheritance to pay down the mortgage, finish the basement, or remodel the kitchen, that money is now intertwined with the marital home. You may get credit for the contribution, but proving it requires meticulous records.
Putting your spouse’s name on the title. If you inherited a piece of real estate or a vehicle and added your spouse to the title, that’s often treated as a gift to the marriage — converting separate property into marital property.
Using it as a down payment on jointly titled property. Same problem. The down payment came from your separate funds, but the asset itself is now jointly owned and presumed marital.
Treating it as “our money.” If you and your spouse routinely spent the inheritance on vacations, household bills, or shared investments, courts may decide you intended it to be marital from the start.
How to Keep Inheritance Separate
The short version: never let it touch marital property.
Open a separate account in your name only. Deposit the inheritance there and don’t use it for joint expenses, mortgage payments, or anything that benefits the marriage as a whole. The account should never have your spouse’s name on it.
Keep it titled in your name only. If you inherit a house, a car, or any titled asset, do not add your spouse to the title. Period.
Keep records. Bank statements showing the original deposit. Probate or estate documents proving where the money came from. Every transaction in and out of that account. The burden of proof in a Missouri divorce is on the spouse claiming property is separate — meaning if you can’t trace it, you can’t protect it.
Don’t reinvest it into shared assets. If you want to use inheritance money to invest, do it in a separately titled account.
Consider a postnuptial agreement. If you receive a substantial inheritance during the marriage, a postnuptial agreement can lock in its separate character so it’s not in dispute years later.
What If You Already Commingled It?
This is where things get fact-specific. Even commingled inheritance isn’t automatically lost — but you’ll need to make a tracing argument.
Tracing is the process of following an asset back to its separate source. If you can show that a specific portion of a joint account or asset came from inheritance funds, courts may award you that portion back as separate property.
For example: you inherited $100,000 and deposited it into a joint account that already had $20,000 in marital savings. You then used $30,000 of the combined funds for a kitchen remodel. With clear records, an attorney can often argue that a meaningful percentage of the remaining account balance is still your separate property.
Tracing is harder when:
- The account has had years of activity without clear records
- Funds have been withdrawn and redeposited multiple times
- The inheritance was small relative to overall account activity
- Records have been destroyed or are incomplete
This is one of the areas where bringing in a forensic accountant can pay for itself many times over in a divorce involving significant assets.
Can My Spouse Claim Some of It Anyway?
Even if your inheritance is unquestionably separate, your spouse may still try to argue for a share through other doctrines.
The “Source of Funds” Argument
If you used inheritance to acquire a marital asset (like a home), Missouri courts recognize a “source of funds” approach. You may get credit for your contribution, but the appreciation in value during the marriage might be considered marital. So the original $50,000 you put down might come back to you, but the $200,000 in equity built up over 15 years could be split.
The “Transmutation” Argument
If your spouse can show that you and they treated the inheritance as joint property — using it for shared purposes, depositing it in joint accounts, openly relying on it as a family asset — a court may find that you transmuted it from separate to marital. Intent matters here.
Spousal Support Considerations
Even when inheritance stays separate from property division, courts can still consider it as a financial resource when deciding spousal support under § 452.335 RSMo. A large inheritance can affect both how much support you owe and how much you might receive.
What If My Spouse Inherited Something? Can I Claim a Share?
The same rules apply in reverse. If your spouse received an inheritance during the marriage and kept it strictly separate, you generally have no claim to it.
But if they commingled it with marital assets, used it for the family home, or depended on it for joint expenses, that opens the door for you to argue some or all of it should be considered marital.
This is particularly important in cases where one spouse received a large inheritance and used it as a substitute for their own income — letting both spouses live a higher lifestyle than the working spouse alone could support. Courts pay attention to that.
Anticipated or Future Inheritance
A common question: “My mother is leaving me money in her will — can my spouse claim part of that?”
No. Future or anticipated inheritances are not divided in a Missouri divorce because they aren’t owned by anyone yet. Until your parent passes and the estate is distributed, the money isn’t legally yours.
That said, courts can sometimes consider an expected inheritance when determining spousal support — if it’s likely to materialize in the foreseeable future and would meaningfully change your financial picture. This is rare and very fact-specific.
What About Inheritance Received After You File for Divorce?
If you receive an inheritance after the divorce petition is filed but before the judgment, it’s still separate property under Missouri law. The classification rules in § 452.330 don’t depend on when the asset was received — they depend on how it was acquired (gift, bequest, descent) and whether it was kept separate.
The complication: if you receive a large inheritance during the divorce, your spouse may try to use it as leverage in spousal support negotiations or to argue for a different division of marital assets.
Common Questions
Is inheritance always considered separate property in Missouri?
By default, yes — inheritance starts as separate property. It only becomes marital if it’s commingled with marital assets or if you take actions that show you intended to gift it to the marriage.
Can my ex get my inheritance if it’s in a trust?
Trusts add a layer of protection, but they’re not bulletproof. If you’re a beneficiary with a vested right to specific income or principal, courts may consider those distributions when dividing assets or awarding support. Discretionary trusts where you have no enforceable right to distributions are usually safer.
What if I used inheritance to buy our house together?
Then it’s complicated. You may be entitled to credit for the down payment as separate property, but the house itself is likely marital. The appreciation during the marriage will probably be split.
Does it matter if my spouse knew about the inheritance?
Knowledge alone doesn’t change the classification. What matters is what you did with it. If your spouse knew you inherited $200,000 but you kept it in your sole name and never spent it on the marriage, it stays separate.
Should I keep inheritance secret from my spouse?
No. Hiding assets in a divorce — even separate ones — can backfire badly and damage your credibility with the court. The right move is to be transparent and properly document the inheritance as separate.
Protect What’s Yours Before It Becomes a Fight
If you’re already heading toward divorce and you’ve inherited money during the marriage, the worst thing you can do is wait. Every day that passes without clear records and proper segregation makes the tracing argument harder.
