Intellectual property (IP) is one of the most commonly overlooked assets in a prenup discussion. A songwriter who builds a catalogue during a marriage, a software developer who writes code while living with a partner, or an author who publishes books throughout a long-term relationship may all find that IP rights become contested at separation. Australian family law treats IP as property, which means it can be included in a property settlement and divided like any other asset. A well-drafted prenup can address this directly.
Why intellectual property is different from other assets
Most assets have a fixed, identifiable value at a point in time. Intellectual property doesn't work that way. A patent might be worth very little when it's registered but generate millions in licensing revenue years later. A novel written during a marriage might still be earning royalties decades after separation. This creates two distinct problems: valuation and ongoing income.
Valuation is difficult because IP value is speculative. Courts and lawyers have to assess the expected future income stream, which involves assumptions about market performance, licensing deals, and the length of the relevant rights. Ongoing income is a separate issue entirely. Even if the IP itself is assigned to one party, royalty streams, licensing fees, and future sales don't stop flowing. Without a clear agreement in place, a former partner may have a legitimate claim to those ongoing earnings.
A prenup can address both problems by specifying how IP is to be treated before any dispute arises.
What types of intellectual property can a prenup cover?
Australian family law doesn't create a special category for IP. It's treated as property under the Family Law Act 1975 (Cth), which means a binding financial agreement (BFA) can address it directly. The types of IP that commonly appear in prenup negotiations include:
- Copyright: books, music, film, software, artwork, and written content
- Patents: inventions, industrial processes, and technical innovations
- Trade marks: business names, logos, and brand identifiers
- Business goodwill tied to personal reputation or creative output
- Licensing rights and royalty entitlements from existing agreements
Each of these can be structured into a prenup with different rules. A prenup might specify that IP created before the relationship remains solely with the creator, that IP created during the relationship belongs to the creator but royalties are shared up to a capped amount, or that all IP is excluded from the shared asset pool entirely.
Pre-relationship IP vs IP created during the relationship
Australian family law distinguishes between assets brought into a relationship and those acquired during it, though both can form part of the asset pool at settlement. Pre-relationship IP is generally easier to protect with a prenup because it's clearly identifiable and predates the relationship. A musician who enters a marriage with an existing catalogue of songs, for example, can specify in a prenup that those works and any income they generate remain separate property.
IP created during the relationship is harder to quarantine. Courts consider both partners' contributions to the asset pool, including non-financial contributions like supporting a partner's creative work, managing the household, or raising children so the other partner could focus on their craft. If a partner enabled the creation of IP by carrying the household financially or practically, they may have a legitimate claim to a share of that IP at separation.
A prenup can't eliminate those contribution arguments entirely. But it can establish a framework that limits the claim, sets a methodology for valuation, or creates a financial offset rather than a transfer of IP ownership. For more on how future assets can be addressed in a BFA, see our article on can a prenup cover future assets in Australia, which covers the broader rules around prospective wealth.
Royalties and ongoing income streams
The trickiest IP issue in a prenup is ongoing income. If a novelist writes three books during a marriage and those books generate royalty income for the next 20 years, a separation today doesn't end the income flow. Under Australian family law, a court assessing the property settlement could treat those royalties as part of the asset pool, or factor the expected future income into the overall division.
A prenup can deal with this in specific terms. Options include a lump-sum buyout provision where the non-creator receives a fixed amount in lieu of any ongoing royalty claim, a time-limited sharing arrangement where royalties are shared for a defined period after separation, or a clean separation clause that assigns all royalties to the creator in exchange for other property concessions.
The key is specificity. A prenup that simply says "IP remains with the creator" without addressing income streams creates a gap that courts may fill in ways the creator didn't intend.
Businesses built around intellectual property
Many creative and technology businesses are largely made up of IP. A software company's value may sit almost entirely in its codebase and brand. A design studio's worth may derive from its portfolio and client relationships. When one or both partners own such a business, the IP question and the business question overlap significantly.
Rockwell Family Law Services advises clients in this situation to address IP and business interests together in the same BFA provisions. A prenup that protects a business but ignores the IP that underpins it may offer less protection than it appears to. Our article on can a prenup protect a business in Australia covers how BFAs can be structured to shield business interests, which is directly relevant when the business value is largely IP-based.
What a prenup can't do with intellectual property
A prenup can allocate IP between partners and set rules for income. It can't override third-party rights. If IP is subject to an existing licensing agreement with a third party, a prenup can't unilaterally alter that agreement. It also can't extinguish a partner's contribution claims entirely where those contributions were substantial and directly linked to the creation of the IP.
Courts retain the power to set aside or vary a BFA in limited circumstances, including where a party didn't receive independent legal advice, where there was duress or unconscionable conduct, or where the agreement produces an outcome that is unjust in the circumstances. This is why the drafting process matters as much as the content. A prenup that addresses IP clearly, was prepared by a qualified family lawyer, and was signed with proper advice on both sides is far more likely to hold than one drafted loosely or signed under pressure.
Getting the drafting right
IP clauses in a prenup require more precision than most other asset provisions. The agreement needs to identify the IP clearly (by category, by registered title, or by description), specify how it is valued if a dispute arises, address income streams separately from ownership, and deal with IP that hasn't been created yet but may be during the relationship.
Rockwell Family Law Services works with clients who hold or expect to hold significant IP assets to draft binding financial agreements that reflect the real commercial value of those rights. The earlier this conversation happens, the more flexibility there is to structure something that protects the creator without creating unfairness to the other partner.
