An inherited home may be sold even though the heirs are not yet registered as owners, but only where the legal and tax chain can support conveyance and registration of the promised right. Before paying a deposit, identify every right-holder and representative, obtain the succession documents and agree in writing what happens if authority or title cannot be proved.
1. Start with the right being sold, not the word ‘heir’
Calling someone an heir says something about the succession; it does not answer the buyer's central question: will I receive and be able to register full ownership of this particular property? A person may be entitled to inherit without yet having been allocated the home. Another may own an undivided share, bare ownership or a right of usufruct. The answer depends on the deceased owner's title, matrimonial property arrangements, the applicable succession law and any acceptance or partition documents.
Ask the seller to define the exact right offered before discussing a deposit: the whole property, an undivided share or a limited right. Under the ordinary Spanish Civil Code, a valid partition gives the recipient exclusive ownership of the allocated asset. Selling an abstract inheritance right before partition is not automatically a sale of a specified share of this home. Someone who already owns a co-ownership share may dispose of that share within the law, but cannot promise the other owners' interests. A listing for “the entire house” needs title documents that support that description. Civil Code, articles 1067–1068.
2. Reconstruct the succession from documents
Normally begin with the death certificate and the certificate of last wills. The latter identifies whether a will was recorded and the notary who holds the latest one; it is not a substitute for the authorised copy of the will. Where there is no will, the appropriate declaration of intestate heirs must establish the people entitled. Depending on the case, a succession agreement or European Certificate of Succession may also be relevant. Then inspect acceptance and partition or allocation documents. If the proposal is a joint sale without a prior allocation, establish that all necessary interested parties will participate.
Do not rely on a photograph of one page of the will. Compare names, dates of death, substitutions, legacies, a spouse's rights, shares and conditions with the property on offer. A deed allocating a different property to an heir does not prove authority to sell this one. If several deaths created successive inheritances, trace every transfer. Obtain complete legible copies so that the notary and Land Registry can assess the chain. Ministry of Justice · Mortgage Law, article 14.
3. Identify every person whose signature or authority is needed
With several heirs, the signature of one of them seldom secures a transfer of full ownership. Identify the holders of every right the buyer expects to acquire, including a pre-existing share, bare ownership or usufruct. Do not assume that every surviving spouse has the same share. Matrimonial property, separate property, a will and the applicable succession law may produce different results.
If an interested person lives abroad, inspect the power of attorney before another person signs for them. Disposal of property requires express authority under the Civil Code; check that the instrument covers the transaction and any deposit agreement the representative proposes to sign. A minor, protected person or conflict of interest may call for specific controls or authorisations. Do not turn an unresolved authority issue into a non-refundable reservation. Civil Code, article 1713.
4. Check the Land Registry chain, not just the displayed name
Obtain a recent nota simple and compare the registered property, cadastral reference where shown, ownership interests, usufructs, mortgages, attachments and restrictions with the succession documents. An extract reports the registered position when issued; refresh it close to completion. Read the deed by which the deceased acquired the property as well. The fact that the deceased remains registered does not invariably prevent a sale.
The real question is whether the transfer from the registered owner through the inheritance to the buyer can be documented and registered. Spanish law requires a proper chain. The Directorate General has recognised cases in which all heirs whose interests together cover the ownership sell the inherited asset jointly without first allocating and registering it in their names. That possibility does not dispense with proof of the succession, authority or relevant taxes. Indeed, a 2025 decision refused registration on the particular facts because of a conflict of interest. If the chain is unfinished, agree in writing which documents or deeds must be produced before completion and who pays for them. DGSJFP decision of 6 March 2025.
5. Inheritance tax and municipal tax: ask for evidence
A property sale should not leave succession tax documents as an unexplained problem for completion day. Request evidence of the inheritance-tax filing or assessment that applies, and ask the notary or adviser what the Registry will require for the title chain. The competent tax authority and applicable rules vary with residence and territorial connections; there is no single tax rate or national form that fits every estate. The Spanish Tax Agency administers certain non-resident cases, but not all inheritances.
Check the status of municipal capital gains tax (plusvalía municipal) where it applies, and any fiscal impediment to registration. Article 254 of the Mortgage Law deals with evidence for registration and allows specific evidence of filing, declaration or notification for municipal tax; it is inaccurate to demand a payment receipt in every situation. A local property-tax (IBI) receipt is a different document and does not show that the estate's succession tax was dealt with. The contract should also allocate the cost of formalising the inheritance and removing charges deliberately. Mortgage Law, article 254 · Spanish Tax Agency.
6. International heirs can change the legal route
A Spanish property is not automatically inherited under the ordinary Spanish Civil Code. For deaths from 17 August 2015, EU Succession Regulation 650/2012 generally points to the law of the deceased's habitual residence at death, subject to the possibility of choosing the law of nationality under its conditions. Spanish territorial civil laws can also matter. The applicable law may alter who inherits, what a spouse receives, how assets are divided and which documents establish those rights.
A foreign will, a European Certificate of Succession, heirs in several countries or successive estates call for document planning before a deposit deadline is agreed. Translation, legalisation or apostille and verification of foreign instruments may take time; avoid promising a completion date based on assumption. The buyer needs a concrete route to a registrable deed, not a broad assurance that “the inheritance is done”. EU Succession Regulation 650/2012, articles 21, 22 and 83.
7. Turn each uncertainty into an express deposit condition
The arras agreement should name all parties, identify the property and exact right being acquired, state the price and say who receives and holds the money. If the inheritance papers are incomplete, “the seller will regularise the estate” is not enough. List the outstanding documents, who will obtain them, a realistic deadline, how every signer's capacity will be verified and whether completion will follow prior inheritance registration or a legally supportable joint sale. Deal expressly with charges, usufruct, possession and the party responsible for clearing each impediment.
Agree what happens if an heir refuses, another right-holder emerges, a power proves insufficient, the title chain cannot be shown or tax evidence prevents registration. A carefully drafted condition can provide for return of the buyer's deposit if an objectively defined title requirement is unmet by a specified date. Remedies and any extension must fit the rest of the contract. Do not assume that every payment labelled “deposit” allows either party to walk away by forfeiting it or returning double. The withdrawal mechanism associated with article 1454 of the Civil Code needs a clear agreement. If an agent holds a reservation sum, verify who controls it and whether the agency's form reflects these protections. Civil Code, article 1454.
8. Hypothetical example: two siblings market the whole family home
A house remains registered in a deceased person's name. Two children show a will and say they can sell it for €320,000. The Land Registry extract also shows a right in another person's favour; a third sibling is absent from the negotiations. The estate agent asks for a €10,000 reservation to take down the listing. At this stage, there is no basis to say that the two negotiators can transfer full ownership free of the registered right, even if both are heirs.
A prudent buyer would ask for the complete succession file, clarify the third person's right and the absent sibling's position, check any representative's express authority and obtain a current Land Registry extract. Only then should a reservation or deposit identify every necessary signer and provide a documented exit if the promised title cannot be conveyed. The remedy is not inevitably “register the inheritance first”: a properly documented joint sale may also be possible. The answer depends on the actual title and registration assessment.
9. A practical order of work before transferring money
Begin with the property's identity and a fresh Registry extract. Build a simple table of who owned, inherited or retains each right: full ownership, co-ownership share, bare ownership and usufruct. Record who will attend, who needs a power and what remains to evidence taxes and remove charges. With that map, have a notary and lawyer confirm the documentary route to a deed that can be registered. Only then settle the deposit terms, calendar and handling of the money.
Where there is a real succession dispute or unresolved title risk, the buyer can postpone, make the obligation expressly conditional or walk away before committing funds.

Common questions
Must the inheritance be registered before the sale?
Not in every case. A joint sale by all necessary interested parties may be possible with a provable succession title and registration chain. The documentary and tax route must allow the buyer's title to be registered; a promise to fix it later is insufficient.
Is the certificate of last wills itself the will?
No. It identifies whether a will was recorded and the relevant notary. Obtain the applicable succession title, such as the authorised copy of the will or a declaration of intestate heirs.
Can one sibling sign the deposit agreement for everyone?
Only with sufficient authority from every right-holder whose consent is needed. Family relationship, an informal conversation or a copy of the will does not amount to an express power to dispose of the property.
What if there is a usufruct?
Bare ownership and usufruct are different rights. Check the instrument and whether the usufruct remains in force, then establish how its holder will participate or the right will end before full ownership is promised.
Do I automatically lose my deposit if the inheritance is not ready?
That depends on the contract and facts. Before paying, agree a documentary condition, deadline and return of the money if the promised right cannot be conveyed. The Civil Code's withdrawal-style arras rules do not arise merely because a payment is called a deposit.
