How Are Intellectual Property and Royalties Divided in a California Divorce?
Quick Answer: In California, intellectual property created during the marriage is generally community property under Family Code section 760, and the royalties it earns are usually community too. Intellectual property created before marriage or after separation is separate. When a work spans both periods, the income is apportioned. Dividing it means splitting the income, offsetting with other assets, or a buyout.
A patent, a copyright, a trademark, or a stream of royalties can be one of the most valuable things a couple owns, and one of the easiest to overlook. For founders, creators, and professionals, these intangible assets deserve the same attention as a house or a retirement account.

What Counts as Intellectual Property?
Intellectual property is a set of legal rights in something you created or built. In a divorce it can include patents that protect an invention, copyrights in books, music, software, or film, trademarks that protect a brand name or logo, and trade secrets. Just as important are the income streams these rights produce, including royalties, licensing fees, and residuals. All of it is property, even though none of it is something you can hold in your hand, and all of it can be divided.
The Core Rule: When Was It Created?
Characterization turns on timing. Under Family Code section 760, property acquired during the marriage is community property, and that includes intangible assets like intellectual property. Under section 770, property created or acquired before marriage, or received by gift or inheritance, is separate. Under section 771, what a spouse earns and creates after the date of separation is separate. So the first question in any intellectual property dispute is simple: when was the work created, and whose effort created it?
Royalties Follow the Underlying Intellectual Property
Income generally takes the character of the asset that produces it. If a copyright, patent, or trademark is community property, the royalties and licensing income it generates are usually community too, even if the checks keep arriving for years after the divorce. If the intellectual property is separate, the income is usually separate, unless community effort or community funds increased its value during the marriage, in which case the community may be owed a share.
Apportionment When a Work Spans the Marriage
Many real cases are not cleanly community or separate, because the work straddles the marriage. Consider these:
• A book started before marriage and finished during it, still earning royalties today.
• A patent invented during the marriage but licensed for income after separation.
• A brand built partly before and partly during the marriage, now generating licensing fees.
In these situations the court apportions the income based on when the creative work and effort actually happened. This is the same logic California uses to divide stock options and pensions that vest across a marriage, which we touch on in our posts on RSUs and on dividing retirement, and it can get technical fast.
How the Asset Actually Gets Divided
Because you cannot cut a copyright in half, courts and settlements use a few practical methods:
• Ongoing revenue sharing, where both spouses receive an agreed percentage of future royalties and licensing income.
• Offsetting with other assets, so one spouse keeps the intellectual property and the other receives equal value in a home, a retirement account, or cash.
• A buyout, where one spouse pays the other for their community share and keeps the asset outright.
Do Not Forget to Disclose It
Intellectual property is a classic forgotten or hidden asset, precisely because it is intangible and easy to leave off a disclosure. That is a serious risk. California requires full disclosure of all assets, and hiding intellectual property can be treated as concealment with severe consequences, a subject we cover in our posts on financial disclosures and on finding hidden assets. If your spouse created something of value during the marriage, it belongs on the table.
Valuation Is Hard, So Get It Right
Putting a number on intellectual property is genuinely difficult, because you are valuing future royalties, licensing potential, and brand strength that may not have peaked yet. This is where a forensic accountant or a valuation expert earns their fee, and where a lawyer who understands both the law and the business side adds real value. We cover the experts in our posts on the forensic accountant and on business and equity valuation.
Even intellectual property that has not been released or has not yet issued can carry real value. A pending patent application, an unreleased film, a manuscript already under contract, or a trademark still building recognition each represents future income the court can account for. A work does not have to be earning money today to be worth dividing tomorrow.
Frequently Asked Questions
I created it, so isn't it mine?
Not necessarily. If you created it during the marriage, it is generally community property even though only you did the work. Character depends on the timing, not on whose name is on it.
What about royalties that arrive after we divorce?
If the underlying intellectual property is community, its royalties generally stay community and are apportioned, even when the payments come in years later.
My intellectual property is not making money yet. Does it still count?
Yes. Future earning potential is an asset. A patent or copyright with no current income can still have real value that must be accounted for.
Can I keep my intellectual property and give up something else?
Often, yes. Offsetting the value against other assets, or buying out your spouse's share, is a common way to keep the asset intact.
