The Contador-Partidor in Spain in 2026: CC Article 1057, the Testamentary Partition Accountant and How It Differs From the Albacea

The contador-partidor is the partition specialist of Spanish succession law: the person appointed under Article 1057 of the Civil Code to inventory, value and divide a deceased person’s estate among the coheirs. The testator can name one in the will, or if none is designated, a notary can appoint one datively at the request of heirs representing at least 50 per cent of the estate. The role is distinct from the albacea (testamentary executor under Article 892), who ensures the will’s provisions are carried out, and the heredero, who receives the assets. For a non-resident owner of Spanish property, understanding when and how a contador-partidor operates can mean the difference between a smooth estate division and a protracted cross-border dispute.

What is a contador-partidor and when does one operate?

A contador-partidor is a third party empowered to carry out the partition of a Spanish inheritance. Article 1057 of the Civil Code governs the appointment: the testator may delegate the “simple faculty of making the partition” to any person who is not a coheir, either by an act inter vivos or mortis causa in the will. The appointee need not be a legal professional, though in practice lawyers and notaries’ trusted associates often fill the role.

When the testator has not named a contador-partidor, or the named person cannot or will not serve, Article 1057’s second paragraph provides a fallback mechanism. A notary or judicial secretary can appoint a contador-partidor dativo at the request of heirs and legatees who collectively represent at least 50 per cent of the estate, with citation of other interested parties whose domicile is known. The partition produced by a dativo appointee requires approval by the notary or judicial secretary unless all heirs and legatees expressly confirm it. This dativo route was reformed by the Ley 15/2015 de Jurisdicción Voluntaria, which transferred the appointment competence from the courts to notaries and judicial secretaries for cases outside litigation.

The third route, under Article 1058, applies when the testator made no partition and named no contador-partidor: if all heirs are of age and have free administration of their assets, they may distribute the estate as they see fit by mutual agreement. Article 1059 covers the failure of that agreement: when adult heirs cannot agree, the matter proceeds through the judicial process under the Ley de Enjuiciamiento Civil.

How does the contador-partidor differ from the albacea and the heredero?

The distinction matters because foreign property owners often conflate the three roles. The heredero receives the assets. The albacea, appointed under Article 892, executes the testator’s wishes: arranging the funeral, paying cash legacies, supervising the will’s provisions and conserving the estate’s assets during the executor’s mandate. The contador-partidor performs the mechanical division: the inventory, valuation and adjudication of specific assets to specific heirs.

The testator can combine the albacea and contador-partidor roles by expressly granting partition powers to the albacea under Article 1057. Without that express grant, the albacea’s default faculties under Article 902 do not include partition, which remains the contador-partidor’s domain. The practical implication for a non-resident writing a Spanish will is that naming an albacea alone does not ensure the estate will be divided; a separate contador-partidor appointment, or an express Article 1057 grant to the albacea, is needed for the partition to be carried out by a designated person rather than left to the heirs’ agreement or a dativo appointment.

What powers and duties does the contador-partidor have?

The contador-partidor’s core function is the partición: the technical operation of dividing the estate. This involves three stages drawn from the Civil Code’s succession framework:

1. Inventario: cataloguing all assets and liabilities of the estate. When any coheir is subject to patria potestad or tutela, or has measures of support under the Ley 8/2021 reform, Article 1057 requires the contador-partidor to inventory the assets with citation of the legal representatives or support figures.
2. Avalúo: valuing the assets at the time of adjudication. The valuation date matters because Article 1074 measures lesion by the value of things “when they were adjudicated”.
3. División y adjudicación: allocating specific assets to specific heirs, respecting the testator’s wishes and the equality principle of Article 1061, which requires that each heir receive things of the same nature, quality or species where possible.

Article 1062 addresses indivisible property: if a thing cannot be divided or would lose value by division, it can be adjudicated to one heir who compensates the others in cash. But any single heir can demand its sale at public auction with outside bidders admitted, overriding the in-kind allocation. Article 1063 requires reciprocal accounting among coheirs for rents, useful and necessary expenses, and damages caused by malice or negligence. Article 1064 allocates partition costs: expenses in the common interest are deducted from the estate, while those in a single heir’s interest are charged to that heir.

When real property is involved, the partition must be formalised in a public deed (escritura pública) before a notary for registration in the Land Registry. This is the practical step that transfers registered title to the adjudicated heir.

Can a partition made by a contador-partidor be challenged?

Yes, and the 2026 Supreme Court has sharpened the rule. Article 1074 of the Civil Code allows the rescisión of partitions “by cause of lesion in more than a quarter part”, measured by the value of the things when they were adjudicated. This is the last surviving form of the Roman actio ultra dimidium in Spanish law: if an heir receives assets worth less than three quarters of what they should have received, they can seek rescission.

The critical distinction, confirmed by STS 655/2026 of 28 April 2026 (Sala Primera de lo Civil, ponente Seoane Spiegelberg, ECLI:ES:TS:2026:1947, recurso 5440/2021), is that a partition made by a contador-partidor designated by the testador under Article 1057 is fully subject to the Article 1074 rescission action. Only a partition made personally by the testator under Article 1056 enjoys the restrictive Article 1075 exception, which limits challenges to cases where the legitima of forced heirs is prejudiced or where the testator’s actual will can be shown to differ from the partition.

The Supreme Court clarified that the jurisprudential “equivalence” between a testator’s partition and a contador-partidor’s partition refers only to their unilateral (non-contractual) character, distinguishing both from the conventional partition of coheirs under Article 1058. It does not mean identical impugnation regimes. The testator’s own partition, made in exercise of their omnímodas facultades distributivas over their own patrimony, sits outside the rescission action. The contador-partidor’s partition, made under a delegated mandate, does not. The ruling aligns with STS 119/2005, 108/2014 and 280/2022, and resolves a confusion introduced by a Supreme Court ruling of 18 May 2010 that the Audiencia Provincial had relied on but that neither the Supreme Court nor the parties could locate in the records.

The practical lesson for anyone drafting a Spanish will is clear: a testator who partitions personally in the will (Article 1056) gives the heirs the narrowest grounds to challenge it. Delegating to a contador-partidor (Article 1057) preserves the heirs’ full Article 1074 rescission right for lesion exceeding 25 per cent.

What are the time limits and bars to the rescission action?

Article 1076 sets the limitation period at four years from the date the partition was made. Article 1078 bars the action for any heir who has already sold all or a considerable part of the immovable property adjudicated to them, on the logic that alienation implies acceptance of the allocation. Article 1077 gives the defendant heir a choice: indemnify the damage in money or in the same type of property that caused the prejudice, or consent to a new partition. A new partition does not affect heirs who were not prejudiced or who received no more than their share.

Article 1079 limits the remedy for omitted assets: if the partition simply left out some objects or values, the partition is not rescinded but completed or supplemented with the omitted items. Article 1068 confirms that a legally made partition confers exclusive ownership of the adjudicated assets on each heir, extinguishing the community of heirs (the estado de indivisión) that exists before partition.

When must a contador-partidor be used for a Spanish estate?

Situation	Governing article	Who partitions
Testator partitions personally in the will	Art 1056 CC	The testator
Testator names a contador-partidor in the will	Art 1057.1 CC	The appointed contador-partidor
No will, or no contador-partidor named, heirs agree	Art 1058 CC	The coheirs by mutual agreement
No will, heirs cannot agree, 50%+ request it	Art 1057.2 CC	Notary or judicial secretary appoints a dativo
Minor or protected coheirs involved	Art 1057.3, Art 1060 CC	Contador-partidor must inventory with citation of representatives; judicial approval may be required

The table shows the five routes a Spanish estate can take to partition. The testator’s own partition (Article 1056) is the most protected from challenge. The contador-partidor testamentario (Article 1057.1) is the most common delegation. The dativo route (Article 1057.2) applies when no will exists or the named contador-partidor is unavailable. The conventional partition (Article 1058) works when heirs agree. The judicial route (Article 1059) is the last resort.

Why does the contador-partidor matter for non-resident property owners?

A non-resident owner of Spanish property faces a structural problem at succession: the heirs may live in different countries, may not speak Spanish, and may not agree on how to divide a property that cannot be physically split. Article 1062 allows a single heir to force the sale of indivisible property at auction, which can mean disposing of a family villa below market value.

Appointing a contador-partidor in the Spanish will addresses this. The contador-partidor can value the property, allocate it to one heir with a cash equalisation payment to the others, or arrange a sale at fair market value rather than a forced auction. Because the contador-partidor is not a coheir, the partition has a neutral authority behind it that can reduce the scope for disagreement. The non-resident inheritance process in Spain involves notary acceptance, tax filing via Modelo 650 and Land Registry inscription, all of which require a completed partition.

For estates involving forced heirs under Spanish law, the contador-partidor must also respect the legitima: the reserved share of the estate that goes to children and descendants (or, failing them, parents and ascendants) under Article 807. A partition that violates the legitima can be challenged regardless of who made it. The spanish will for property owners guide explains how the will itself can pre-allocate the legitima to streamline the contador-partidor’s work.

How does the Ley 15/2015 reform change the dativo appointment?

Before the Ley 15/2015 de Jurisdicción Voluntaria, the dativo appointment of a contador-partidor under Article 1057.2 was a judicial matter. The reform transferred competence to notaries and judicial secretaries (Letrados de la Administración de Justicia), allowing families to appoint a contador-partidor dativo without initiating court proceedings. The reform aligns with the broader policy of moving non-contentious matters out of the courts and into the notarial system, reducing the time and cost of estate administration.

The requirement remains that heirs and legatees requesting the appointment represent at least 50 per cent of the estate, and other interested parties must be cited if their domicile is known. The partition produced by a dativo appointee requires approval by the notary or judicial secretary unless all heirs and legatees expressly confirm it, adding a safeguard that does not apply to a contador-partidor named by the testator, whose partition takes effect without external approval.

What happens if a coheir has measures of support?

The Ley 8/2021 reform, effective from 3 September 2021, added a fourth paragraph to Article 1057: if a coheir has support measures (medidas de apoyo) established under the disability reform, the contador-partidor must follow what those measures provide. Article 1060 was also amended to address the representation of persons with support needs in the partition, requiring judicial approval of partitions made by a curador with representation powers, and by a judicial defender appointed to act in the partition on behalf of a minor or a person with support measures.

This means that for estates involving a coheir who lacks full capacity, the contador-partidor’s work is subject to additional procedural safeguards. The inventory must be made with citation of the support figures, and the partition may require judicial approval depending on the representation arrangement. The reform replaced the old tutela and patria potestad language with the broader “medidas de apoyo” framework, reflecting the shift from substitution to support in Spanish disability law.
