A creative work, a patent or a trademark can have value that grows over time, produce royalties, support a business venture or become the basis of a professional project. If you are about to get married, it is understandable to wonder whether these assets remain yours, whether your spouse can claim financial rights and what happens in the event of separation or divorce.
I will explain which distinctions truly matter. The point is not merely establishing who conceived a work or registered a trademark: the family property regime, contracts already concluded, any activity carried out in a company and the financial contributions of the other spouse also have an impact. We will also examine what an agreement can regulate before marriage and which issues cannot be resolved with a generic formula.
A prenuptial agreement is not a general waiver of family rights
In Italy, there is no single model of a "prenup" equivalent to the one widespread in other legal systems. However, an agreement concluded before or during marriage can be relevant if it concretely regulates property relations between spouses, with an interest worthy of protection and without turning the future marital crisis into the cause of the contract.
The Court of Cassation, by order no. 20415 of July 21, 2025, recognized the validity of a property agreement linked to the possible breakdown of the marriage: the crisis can operate as a condition that makes the agreement effective, while the contract must have its own economic function, such as the acknowledgment of a financial contribution or the arrangement of specific assets. This reference is also useful for intangible assets, but it does not authorize considering any pact drafted before the wedding as valid. Review by the Court of Cassation on order no. 20415/2025
Precision is decisive. An understanding that identifies a software already created, a loan received to develop it and the criterion for repaying that loan is different from a clause that declares, in absolute terms, that a spouse waives in advance any economic consequence of a future separation or divorce. In the second case, family protections come into play and cannot be treated as a normal commercial transaction.
Furthermore, decisions requiring an up-to-date assessment of the children's best interests remain outside the prior availability of the spouses. A property agreement can therefore help distinguish ownership, investments and proceeds, but it does not replace the rules applicable to family breakdown when it actually occurs.
First distinction: author, owner of economic rights and trademark owner do not always coincide
"Intellectual property" does not indicate a single right. Copyright protects works of creative intellect, such as books, music, photographs, graphic works and, in cases provided by law, computer programs and databases. A patent instead concerns a technical invention; a trademark distinguishes products or services on the market. To protect an intangible asset in marriage, one must first understand which right exists and who owns it.
In copyright law, the author retains moral rights over the work, meaning the personal bond with the creation and the ability to claim authorship or oppose prejudicial modifications. Economic exploitation rights, such as publishing, reproducing, distributing or licensing the work, instead have a patrimonial dimension and can be subject to transfers or licenses. The copyright law distinguishes these two spheres and also governs the circulation of economic rights. Law no. 633 of 1941 on copyright, current text on Normattiva
Marriage does not turn the spouse into a co-author. If a person writes a novel, composes a song or creates a creative project, the marital relationship does not grant the other spouse the status of author. However, the property issue may concern the proceeds of the work, investments sustained by the family, a publishing or licensing contract, or any creative contribution actually provided by the other spouse.
For patents and inventions, further attention is required. The Industrial Property Code governs the attribution of rights over inventions and provides specific rules for inventions made within the scope of an employment relationship. Therefore, it is not enough to say that the idea was born during marriage: the inventor's work activity, the content of the employment contract, the compensation and the potential role of the enterprise all matter. Industrial Property Code
The trademark requires looking at the registered owner. It can belong to a natural person, a company or multiple subjects. If the owner is a company, the spouse cannot dispose of the trademark as if it were a personal asset of the other partner: the agreement between spouses can regulate their economic relations, but it does not replace corporate decisions nor does it unilaterally modify the ownership resulting from the company's registers and contracts.
Community or separation of property: what changes for economic value
The property regime affects purchases and proceeds above all. In the absence of a different choice, the legal regime is the community of property. The Civil Code governs assets entering the community, those excluded and the matrimonial conventions with which spouses can choose the separation of property or adopt other permitted regulations. Civil Code, rules on property relations between spouses
This does not mean that every copyright, patent or trademark accrued during marriage automatically becomes common in every component. For an intangible asset, at least four elements must be distinguished: the personal quality of author or inventor; the economic or industrial right; the contract governing its exploitation; the income actually produced. Date of creation, filing, registration, acquisition, source of funds and management methods can lead to different consequences.
Separation of property prevents some misunderstandings, not all. It can be a suitable choice when both wish to keep individually made purchases separate. However, it does not resolve a loan that one spouse has paid for the development of the other's work, a corporate shareholding registered in just one name, a creative collaboration or a licensing pact with third parties. For these relationships, documents indicating cause, amount, restitution and granted rights are needed.
The matrimonial convention requires the form of a public deed and must be annotated in the margins of the marriage certificate to be enforceable against third parties. A private agreement regulating an investment or license between spouses is therefore different: it can have its own contractual function, but it does not change the matrimonial property regime on its own.
Useful clauses for works, patents, trademarks and royalties
An effective agreement starts from identifiable assets. It is useful to clearly indicate which works, patent applications, patents, trademarks, domain names, software or contracts are intended to be considered. For a work, a description, a certain date and reference to the publishing or licensing contract may be useful; for a trademark, registration data; for a patent, the application or title number and the registered entity.
nA clause can then clarify what remains personal: for example, ownership of economic rights in works created before marriage, the exercise of the author's moral rights, shares in a company holding an already acquired trademark or patent. The same clause must avoid absolute formulas that ignore a subsequent transfer, voluntary community of property or a real creative collaboration between spouses.
The contributions of the other spouse deserve independent regulation. If one of the spouses finances the registration of a trademark, research activity, prototype production or promotion of a work, it must be established whether it is a loan, liberality, investment, participation in a common project or consideration for a performance. Without this distinction, a sum paid during the course of the marriage can become difficult to qualify precisely when the personal relationship is interrupted.
An agreement can also provide for a reimbursement criterion, linked to documented expenses or a determined contribution, and identify relevant documents: invoices, bank transfers, publishing contracts, royalty statements, excerpts of the account dedicated to the project. Proof of the contribution does not serve to turn the financing spouse into the automatic owner of the intangible right; it serves to make the economic reason of the pact legible.
When the asset is exploited through a company, the family agreement must respect the bylaws, shareholders' agreements, resolutions and share registrations. A spouse can obtain a reimbursement or a different property arrangement in internal relations, but cannot acquire powers belonging to the company, directors or other shareholders through a simple private writing.
What an agreement cannot decide in advance
Writing "no future claims" is not enough. An indistinct waiver of every economic right linked to marital crisis does not offer the same reliability as a pact regulating a concrete property event. Any divorce allowance responds to its own criteria, and its discipline cannot be simplified into a formula that preemptively neutralizes every protection, especially if a recognizable balance between the positions of the parties is lacking.
It is also necessary to distinguish the value of a right from the income it can produce. Ownership of a work or a patent does not necessarily coincide with the sums collected over time; likewise, a royalty alone does not demonstrate who contributed to the creation or financing of the asset. Each item must be kept separate to prevent the contract from using generic words, such as "intellectual property" or "earnings", for very different realities.
Finally, the protection of children cannot be anticipated with rigid rules on maintenance, the family home or parental responsibility. If the family goes through a crisis, these decisions require an assessment referred to the concrete situation and the best interests of the children at that time.
How to set up an informed choice before the wedding
The most useful sequence is to distinguish ownership and collaboration. First, pre-existing rights, registrations, licenses and involved subjects are identified; then it is clarified whether the other spouse contributed money, creative work or business activity. Only afterwards does it make sense to choose the property regime and prepare any agreement on reimbursements, attributions or proceeds.
For an initial comparison, registration titles, patent applications, employment or collaboration contracts, licenses, publishing contracts, the bylaws of any involved company and documentation of payments are normally useful. There is no need to accumulate irrelevant documents: what is needed are those showing who created, acquired, financed or exploited the intangible asset.
Frequently asked questions
Can I protect a work created before marriage?
Yes, but rights and proceeds must be distinguished. Being an author does not depend on marriage, and moral rights remain tied to the author's person. It is useful to identify the work, exploitation contracts and already foreseen royalties. If the other spouse finances activities related to the work, their contribution can be regulated separately without automatically granting them the status of author.
Does separation of property automatically protect patents and trademarks?
No, it only avoids certain property effects on purchases. It does not establish who is the author, inventor or owner of a trademark, nor does it resolve relations with companies, publishers, licensees or employers. For those profiles, registrations, contracts, date of acquisition and real economic contributions matter. Separation of property must therefore be coordinated with specific documents.
Can I provide that royalties remain solely with the creator of the work?
Ownership can be clarified and concrete property relations regulated. However, the clause must identify the work, contract and economic flows to which it refers. It is not prudent to use a generic waiver by the spouse of any future right, because proceeds, economic contributions and protections connected to marital crisis can have different rules.
Does the spouse who finances a patent become the owner of the invention?
Not automatically. Financing can give rise to a credit, an investment or a different contractual relationship, but it does not single-handedly transform the financier into the inventor or patent owner. The answer also depends on who filed the title, the inventor's employment relationship and the content of the agreement with which the sums were paid.
Can a prenuptial agreement eliminate any allowance in case of divorce?
A general formula does not provide a reliable guarantee. Property agreements can regulate a concrete event, such as a financial contribution or the arrangement of identified assets. It is different to claim to waive in advance and indiscriminately the economic protections that could come into relief in a future marital crisis: that clause requires particular caution and should not be confused with a normal property pact.
A useful pact must describe what it intends to regulate
The protection of intangible assets stems from document consistency. Property regime, ownership of rights, corporate relationships, licenses and economic contributions must tell the same story without contradicting each other. A well-constructed agreement does not promise to resolve every effect of a future crisis: it identifies the asset, clarifies the economic reason of the understanding and leaves out what the law requires to be assessed at the concrete moment.
