The patrimonial and extrapatrimonial rights do not form two watertight blocks. Contemporary doctrine confirms this: the gradual patrimonialization of certain personality attributes (image, voice, personal data) blurs a summa divisio that civil law presents as structuring. Understanding this classification requires mastering its technical criteria, but also identifying its flaws.
Criteria of pecuniary nature and assignability: what the summa divisio really covers
The distinction is based on two cumulative criteria. A right is patrimonial when it is capable of pecuniary evaluation and falls within the patrimony in the sense of the Aubry and Rau theory. A right is extrapatrimonial when it escapes any monetary evaluation and remains attached to the person itself.

The criterion of assignability derives from the first. Patrimonial rights are assignable inter vivos (sale, donation, exchange), transferable upon death, seizable by creditors, and subject to prescription. Extrapatrimonial rights are in principle non-assignable, non-transferable, non-seizable, and imprescriptible.
We observe that most popular articles stop there. They omit that these criteria have been deemed insufficient by a large part of the doctrine, precisely because pecuniarity is not binary. A right may not have autonomous market value while generating major economic effects – this is the case with the right to one’s image exploited through a licensing contract.

To delve deeper into the definition of patrimonial and extrapatrimonial rights, one must examine how the legal regime of each category behaves in the face of hybrid situations imposed by practice.
Patrimonial rights: legal regime and subcategories in civil law

The civil code organizes patrimonial rights into three subcategories, each with a significantly different regime.
- Real rights directly pertain to a thing. The right of ownership (art. 544 of the civil code) is the model: it grants its holder the usus, fructus, and abusus. Dismembered real rights (usufruct, servitudes) only grant part of these prerogatives.
- Personal rights, or rights of claim, establish a legal link between a creditor and a debtor. Their object is a performance: to give, to do, or not to do. Lease, loan, and employment contracts are classic illustrations of this.
- Intellectual rights pertain to immaterial creations (patents, trademarks, copyrights). Their particularity lies in the coexistence of a patrimonial aspect (assignable exploitation right limited in time) and an extrapatrimonial aspect (moral right of the author, perpetual and inalienable).
It is this third category that reveals the porosity of the distinction. Copyright illustrates a single subjective right of which one component is assignable, subject to prescription, and evaluable in money, while the other is not.
Extrapatrimonial rights: attachment to personality and protective regime
Extrapatrimonial rights are linked to the legal personality of the individual. These include the right to respect for private life (art. 9 of the civil code), the right to physical integrity, the right to one’s image, the right to a name, and the right to dignity.
Their protective regime derives from their nature. Non-transferability means that these rights extinguish upon the death of the holder. Non-seizability prevents creditors from seizing them. And imprescriptibility ensures that their holder cannot be deprived of them simply due to the passage of time.
We recommend not to confuse the non-transferability of the right with the transferability of the action for damages. The action for damages for an extrapatrimonial infringement is transmitted to the heirs if the victim had initiated it during their lifetime. The Court of Cassation has reinforced this position, which shows that moral harm, once crystallized into a compensatory claim, shifts into the patrimony.
Patrimonialization of image and personal data: a receding boundary
Recent case law regarding the right to one’s image and social networks illustrates a fine articulation between the two categories. The Court of Cassation has reminded that an infringement of the right to one’s image can simultaneously give rise to a right to compensation for moral harm (extrapatrimonial) and to patrimonial compensation when the image has economic value, particularly for public figures.

This dual compensatory regime reflects a broader movement. Several authors have pointed out since the early 2020s an erosion of the clear boundary between patrimonial and extrapatrimonial rights. Image, voice, and e-reputation are subject to licensing or partial transfer contracts while remaining attached to the personality of their holder.
Personal data follow the same trajectory. They are protected by an extrapatrimonial framework (respect for private life, right to be forgotten), but their commercial exploitation by digital platforms gives them considerable economic value. No text in the civil code clearly resolves their qualification.
Family empowerment and protection of adults: a regime that unifies the two categories
In adult protection law, family empowerment measures allow the authorized relative to act in court not only for patrimonial rights but also for certain extrapatrimonial rights of the protected person. The relative can thus defend the physical integrity or housing of the vulnerable adult.
The judicial practice treats the defense of both categories of rights in a unified manner within the framework of vulnerability. This common procedural treatment further weakens the practical significance of the classic distinction.
Recent doctrine also emphasizes the paradox of compensation: an infringement of an extrapatrimonial right results in the allocation of damages, thus creating a patrimonial claim. The transition from harm to compensation operates a legal nature conversion that the summa divisio struggles to satisfactorily explain.
The classification of patrimonial and extrapatrimonial rights remains a useful pedagogical and normative tool for organizing civil law. Its technical regime (assignability, transferability, seizability, prescription) retains concrete effects in matters of succession, enforcement proceedings, and prescription.
The increasing patrimonialization of personality attributes compels reasoning in terms of spectrum rather than hermetic categories. Practitioners dealing with issues of image, data, or protection of adults must integrate this porosity into their legal analysis.
