Your partner's children deny you the usufruct: how to claim it

The case, in five lines

What is brought

Declaratory action for the surviving spouse's legítima under article 834 of the Código Civil, seeking commutation of the usufruct by court order under articles 839 and 840 and payment of the income accrued since the death, after the community property has been liquidated. Where the whole division is outstanding, judicial division of the estate under articles 782 and following of the Ley de Enjuiciamiento Civil (the Civil Procedure Act).

Before which court

The sección civil del Tribunal de Instancia (the civil section of the first-instance court) of the deceased's last domicile (art. 52.1.4 LEC), through ordinary proceedings when the amount exceeds the limit for oral proceedings, which is the usual case. Before suing, an appropriate dispute resolution method must be attempted on the same subject matter (art. 5 LO 1/2025), a requirement that also covers judicial division.

Deadline

There is no short lapse period. The claim to demand division does not lapse between co-heirs (art. 1965 CC) and, if the children hold the assets as their own while denying your share, the Tribunal Supremo (the Supreme Court) applies to the claim for the estate the thirty years of art. 1963 CC, counted from when they begin to hold them that way. If you have already signed a harmful division, you have four years from when it was made to rescind it for loss exceeding one quarter (arts. 1074 and 1076 CC).

Who can bring it

Claimant: the surviving spouse who, when the other spouse died, was not separated either legally or in fact (arts. 807 and 834 CC). Defendants: all the heirs, here the two children of the first marriage, who must be sued together. An unmarried partner has no legítima under the common Código Civil.

Financial risk

If the children prove separation in fact, you lose the legítima altogether and costs may be awarded against you under the loser pays rule. Even if you win, the figure is set by the judge on the expert evidence, and under article 840 it is the children who choose between money and a batch of assets. Since LO 1/2025, a party that refuses without good cause the dispute resolution method it was called to receives no costs in its favour (art. 394 LEC).

You are a forced heir even if nobody named you

Article 807 of the Código Civil lists the widow or widower among the forced heirs, 'in the manner and to the extent this Code establishes', and article 834 sets that extent: the spouse who, when the other spouse died, was not separated legally or in fact, and who shares the estate with children or descendants, is entitled to the usufruct of the third reserved for betterment (the tercio de mejora). It is a right that arises from the law, not from the wishes of the deceased or of his children. It makes no difference that there was no will or that the declaration of heirs names only the children: the surviving spouse's legítima exists all the same, and the notarial record usually states it with the words 'without prejudice to the surviving spouse's statutory usufruct share'.

It is not ownership: it is the right to enjoy one third of the estate for life, to collect its income or to use the assets on which it is fixed, while the children keep the bare ownership. In the case described, with a flat that was his alone worth 240,000 euros and half of some premises and accounts held as community property adding up to another 120,000, the estate is 360,000 euros if there are no debts, and your usufruct falls on one third, 120,000. The complaint 'they will not give me the inheritance' hides two misunderstandings: without a will in your favour you did not inherit ownership of his assets, but the children cannot divide either as if you did not exist.

What the will says changes the strategy, not the floor. If your husband left you the usufruct of the whole estate, the usual device is a cautela socini (a clause forcing the heirs to choose): the children either respect it or keep only their strict legítima. If the will does not mention you, that omission does not harm your legítima. And if your husband had a foral civil status (vecindad civil) or the marriage was governed by a regional civil law, the rules are different: in Aragón and Navarra the surviving spouse has a usufruct over all the assets, and in Cataluña the widow's quarter (cuarta vidual) depends on her own means. Which law applies is settled under articles 9 and 16 of the Código Civil before anything is claimed.

Before the estate, what is already yours: community property, the home and household contents

The most expensive mistake is made before anyone talks about usufructs. If you were married under community property, death dissolves the community and it has to be liquidated first: half of the community assets is yours in your own right, not by inheritance, and only the other half, together with his separate assets, makes up the estate on which the third is calculated. When the children's draft awards them the premises and the accounts acquired during the marriage, they are not denying you the usufruct: they are taking assets half of which are yours. And half of the rent from the premises since the death is yours as co-owner.

In that liquidation the Código gives you a preference that almost nobody claims. Where one spouse has died, article 1406 allows the other to ask for the home of their habitual residence to be included with priority in their share, as far as that share reaches, and article 1407 lets that spouse choose between having it allocated in ownership or having a right of use or habitation created in their favour, paying the difference in money if its value exceeds their share. It only works if the home is community property. And be careful about treating as separate property the flat bought before the wedding: if it was the family home and it was finished being paid for with community money, it belongs in part to the community (arts. 1354 and 1357).

The household contents are separate. Article 1321 orders that, when one spouse dies, the clothes, furniture and effects that make up the contents of the couple's habitual home are to be handed to the survivor, without being counted against the survivor's share. It applies under any matrimonial property regime and takes nothing away from your usufruct; the only exclusions are jewellery and artistic, historical or other objects of extraordinary value. When the children try to inventory the furniture, this article ends the argument. And while the community property is being liquidated, article 1408 allows maintenance to be paid to you out of the common assets until you receive your share, to be deducted afterwards in so far as it exceeds the income and rents you would have been entitled to.

Without your signature the children can neither divide nor commute anything

The second idea that changes the case lies in the second paragraph of article 839: until the commutation is carried out, all the assets of the estate remain charged with payment of the usufruct share due to the spouse. Your right is not a mere claim for money against the children: it is a usufruct over a share that burdens the whole estate until, with your consent or by court decision, it is fixed on specific assets or commuted. The Dirección General de Seguridad Jurídica y Fe Pública (the Directorate General for Legal Certainty and Public Faith) repeats it in its rulings: a division made by the heirs needs the consent of the surviving spouse as forced heir, and without it the division does not get onto the Land Registry.

That gives you the strongest position at the table, even if it does not look like it. The children hold the declaration of heirs, but they cannot register the flat free of your right nor share out the accounts with effect against you. Nor can they impose the form of payment on you: under the Tribunal Supremo criterion those rulings rely on, commutation belongs to the heirs but with the agreement of the surviving spouse, and failing agreement the judge decides. And if they ask for an appointed contador-partidor (a partitioning executor named by the court clerk or a notary), article 1057 requires his division to be approved by the Letrado de la Administración de Justicia (the court clerk) or the notary, unless everyone confirms it: that is the moment to object.

The less pleasant side of that strength is that the deadlock also harms you: the accounts stay frozen and the rent from the premises goes to whoever collects it. That is why the strategy is not to wait for the children to tire, but to use the charge on the assets as leverage and to set out in the very first letter everything that is claimed. If there is a risk that they will sell a property, a cautionary notice of the claim (anotación preventiva de demanda) in the Land Registry prevents a buyer from arguing later that he knew nothing; as an interim measure requested before the claim it is not subject to the prior negotiation requirement (art. 5.3 LO 1/2025), although it obliges you to file the claim afterwards within the time allowed.

Article 840: the exit the law reserves for a second spouse

Article 839 gives the initiative to the heirs: they may satisfy the spouse's usufruct by granting a life annuity, the income from specific assets or a cash sum, by mutual agreement and, failing that, by court order. Article 840 turns that rule round precisely for your situation: where the surviving spouse shares the estate with children of the deceased alone, the spouse may require the usufruct to be paid off, at the children's choice, by granting a sum of money or a batch of assets from the estate. The initiative passes to you. The children choose the form, money or assets, but they cannot refuse to pay, and if there is no agreement on the figure the judge sets it.

The legislator had in mind exactly what you are going through: a life usufruct forces you to live for decades alongside bare owners you have no relationship with. Article 840 allows that tie to be cut with a single payment, although it is not always wise: if the usufruct can be fixed on the home you live in, keeping it secures a roof over your head for life. And there are two points almost nobody mentions. Several Audiencias Provinciales (provincial appeal courts) hold that commutation must be requested before or during the division, and that once the division is signed, with the usufruct already fixed, it can no longer be demanded. And if there are also children of the marriage, the most widespread reading is that article 840 does not apply.

The figure is where most of the case is fought, and the Código does not say how a usufruct is valued. The children usually offer the inheritance tax rule: a percentage obtained by subtracting the usufructuary's age from 89, with a minimum of 10 % and a maximum of 70 %. For a 66 year old widow on 120,000 euros, that is 27,600. It is a rule designed to assess a tax, not to measure what you lose, and no article of the Código Civil requires it to be applied. An actuarial report on the real return on the assets over your life expectancy can give considerably more when the assets produce income, and the income accrued since the death is added to it.

If they say you no longer lived together: separation in fact must be proved, not presumed

The only argument that can leave you with nothing lies in article 834 itself: the right belongs to the spouse who, when the other spouse died, was not separated legally or in fact. Legal separation is recorded in a judgment or a deed; separation in fact is recorded nowhere, which is why it is the ground the children take the case to. But the burden of proving it is theirs: article 217 of the Ley de Enjuiciamiento Civil places on whoever alleges them the burden of proving the facts that bar or extinguish the right claimed. It is they who must show that the marriage had ceased to be a shared life before the death, not you who must show that it still was.

Not every physical distance is separation in fact. Admission to a care home because of dependency, a long stay in hospital or living temporarily in different cities for work do not break a marriage: what matters is the end of cohabitation with the intention of ending the shared life. A care home place paid for by you, daily visits logged in the centre's register or medical records identifying you as the wife who accompanies and decides are proof of the opposite. And if there was a crisis and you later lived together again, resuming the shared life ends the separation in fact without any formality; the notified reconciliation required by article 835 applies only to spouses who were legally separated.

What does complicate the case is any trail you yourself may have left: registration on the municipal roll at another address, a divorce petition filed and never withdrawn, an agreement signed even if it was never approved, or messages in which you admit that you 'led separate lives'. Death brings the divorce proceedings to an end, but it does not erase the end of cohabitation that went with them. If there is anything of this kind, it is analysed before claiming and the case is brought with the evidence of cohabitation already gathered: the historical municipal roll, joint income tax returns, accounts carrying the everyday household expenses, witnesses from the building and the centre. And be careful with what is written during the negotiation: one unfortunate sentence in an email to the children becomes their best evidence.

How it is enforced and how much time you really have

Technically, a great deal. The claim to demand division does not lapse between co-heirs (art. 1965) and, if the children keep the assets while denying your share, the Tribunal Supremo applies to the claim for the estate the thirty years of article 1963, counted from when they hold them as their own. In practice, very little: your usufruct is worth less with every year you age, unpaid past income is more contested the further back it goes, and a property sold to a good faith third party complicates everything. And if you have already signed a division that harms you, you have four years from when it was made to rescind it for loss exceeding one quarter (arts. 1074 and 1076).

Before suing, article 5 of LO 1/2025 must be complied with: in civil matters, the claim is only admitted if an appropriate dispute resolution method was attempted first, and the requirement also covers the judicial division of the estate, a special procedure in book IV of the Ley de Enjuiciamiento Civil. Direct negotiation between the parties or their lawyers, mediation, conciliation or a confidential binding offer all qualify, but the subject matter must be the same: that is why the letter covers the whole estate, with community property, share, income and commutation, and not just the home. And if the children have not accepted the estate, the notarial demand under article 1005 obliges them to declare themselves within thirty calendar days, and their silence counts as unconditional acceptance.

Failing agreement, all the heirs are sued together before the sección civil del Tribunal de Instancia (the civil section of the first-instance court) of the deceased's last domicile. The usual route is ordinary proceedings, seeking a declaration of your share, its commutation by court order at the figure resulting from the expert evidence, and payment of the income. Where the whole division is outstanding, judicial division is available, in which article 783.2 of the Ley de Enjuiciamiento Civil calls you to the meeting as surviving spouse; your standing to start it is disputed, because article 782.1 refers to co-heirs and legatees of an aliquot share. We explain its mechanics in the guide on the co-heir who blocks the division.

How we run the case, step by step

1. 1

   Establish what is yours, what is the estate and which law governs

   We gather the death certificate, the marriage certificate with its entries on the property regime, the certificate of last wills, the will or the declaration of heirs and the purchase deeds for each asset. With them we separate community property from separate property and check your husband's civil status (vecindad civil).

2. 2

   Secure the evidence of cohabitation

   Before the children raise it, we request the historical municipal roll for the marital home, the care home receipts and visitor register, the medical reports and the joint income tax returns, and we identify the witnesses. This is the evidence that decides whether you keep the legítima.

3. 3

   Inventory, value and calculate the usufruct

   We request bank certificates of balances at the date of death, land registry extracts and tenancy agreements, the properties are valued and the actuarial report on the usufruct is commissioned. That tells us what your half of the community property, your third and the past income are worth.

4. 4

   Negotiate with a letter that meets article 5 of LO 1/2025

   A letter is sent to all the heirs covering the whole subject matter: liquidation of the community property with the preference over the home where applicable, household contents, recognition of the share, commutation under article 840 or fixing of the usufruct, and income since the death. If there is a risk of sale, a cautionary notice is requested as an interim measure.

5. 5

   Sue before the sección civil del Tribunal de Instancia

   Failing agreement, all the heirs are sued at the deceased's last domicile, with the actuarial report and the valuation, seeking a declaration of the share, commutation by court order and the income. If the whole division is outstanding, judicial division is considered.

6. 6

   Close the division with safeguards

   The judgment or agreement is carried into the deed of division: the sum is collected or the batch of assets received, or the usufruct is registered over the specific assets. If the commutation is by life annuity, security over property is required so as not to depend on the children's future solvency.
