Renouncing an Inheritance in Spain (Renuncia a la Herencia): Rules, Deadlines and the Tax Angle (2026)

Renouncing an inheritance in Spain, a renuncia or repudiación, is a bigger decision than it sounds, because Spanish law transmits debts along with assets, and once made, there is no taking it back. This page covers how a renuncia must be done, the two clocks that can force your hand, who ends up with the share you turn down, and why renouncing in favour of a specific person is a legally different, separately taxed operation.

What a renuncia is, and what it is not

Accepting or renouncing is one of the two choices every called heir faces, alongside accepting a beneficio de inventario. A true renuncia gives up the share entirely: nothing from the estate, and nothing owed for its debts. That second part is the point of renouncing a heavily indebted estate, since pure and simple acceptance makes the heir liable for the estate's debts with their own present and future assets, not only with what was inherited.

The formal requirement: a notarial deed

Art. 1008 CC is unambiguous: «la repudiación de la herencia deberá hacerse ante Notario en instrumento público». There is no private-document version, no verbal renuncia, and no renouncing simply by staying passive, though passivity can eventually count as acceptance under the rule covered below. The notario drafts the escritura de renuncia, which is what gets shown to the tax authorities and to whoever takes the share next.

Total, unconditional, and irrevocable

Art. 990 CC bars a partial, conditional, or term-limited acceptance or renunciation. You cannot renounce half an inheritance, or renounce it only if a certain condition is met, or renounce it for now while reserving the right to accept later. It is all or nothing, immediately.

Once signed, the renuncia is final. Art. 997 CC states that acceptance and renunciation, once made, «son irrevocables», and cannot be challenged except where the consent itself was legally defective, or an unknown will later appears. There is no cooling-off period and no changing your mind because the estate turned out to be worth more than expected.

Co-heirs decide independently

When there is more than one heir, each choice stands on its own. Art. 1007 CC lets some heirs accept while others renounce, and lets each accepting heir choose separately between pure and simple acceptance and a beneficio de inventario. One heir's renuncia does not affect what the others decide about their own shares.

The two clocks: the nine-day bar and the thirty-day trap

Spanish law protects heirs from being rushed, but only up to a point, then it protects everyone else from an heir who never decides.

Art. 1004 CC sets the floor: no action can be brought against an heir to force a decision until nine days have passed since the death. Before that point, nobody, not a co-heir, not a creditor, not a notario, can compel a choice.

After that floor, art. 1005 CC lets any interested party go to a notario, who formally notifies the called heir that they have thirty calendar days to accept purely, accept a beneficio de inventario, or renounce, and warns them at that same moment that silence within those thirty days means the law treats the inheritance as accepted purely and simply, with the full unlimited-liability exposure that comes with it. This interpellatio in iure turns inaction into acceptance, so once the notice is served, doing nothing is itself a decision, and not the safe one.

Who takes the renounced share

A renuncia does not leave the share in limbo. It passes to whoever the will or the law calls next, as if the renouncing heir had never existed. In an intestate succession, that generally means the next relative in the statutory order covered on the declaración de herederos page; under a will, it depends on any substitución the testator provided, or otherwise on the default rule for a vacant share.

Creditors: can they stop you?

Renouncing to avoid an estate's debts is legitimate. Renouncing to keep your OWN assets out of reach of YOUR OWN creditors is different, and art. 1001 CC gives those creditors a remedy. If a renuncia is made to the prejudice of the renouncing heir's own creditors, those creditors can ask a judge for authorization to accept the inheritance in the heir's name, but only up to the amount of their own credit against that heir. Any surplus beyond what satisfies the creditors still does not go to the heir who renounced; it follows the ordinary rule above.

The tax angle: a pure renuncia vs. renouncing in favour of someone

This distinction has real money attached to it, and it is where most confusion happens. A pure and simple renuncia, made without naming who benefits, means the renouncing heir never becomes a taxpayer for that share at all: the person who is next called under the will or the law inherits it directly, and only that person owes the inheritance tax (ISD) on it.

Renouncing in favour of a specific person is a different legal operation entirely, even though it can look similar on the surface. Legally, it is treated as the renouncing heir first accepting the share and then transferring it to the chosen person, which creates two separate taxable events instead of one: the original heir's acceptance is taxed under the ISD, and the subsequent transfer to the named beneficiary is a further taxable transaction. Before signing anything that names a specific beneficiary rather than simply declining the share, get advice on the resulting tax bill, since it can be considerably higher than a clean renuncia.
