Family inheritance disputes can break even the strongest bonds. Are you worried that dividing an estate could end in a falling-out between siblings? You are not alone: conflicts between heirs are more common than you might think, and they can arise whether or not there is a will. In this article we examine why these contentious inheritances occur, what legal options exist in Catalonia to resolve them, and how Iusfamilia, a team of family lawyers specialising in inheritance matters and trained mediators, can help you protect your rights without putting any further strain on your family.
When a parent dies, the combination of grief and financial matters can easily cause friction between children. Disagreements commonly arise for reasons such as:
- Refusal or obstruction by one heir: A sibling refuses to accept their share of the estate or deliberately delays the process, preventing the assets from being distributed. It is not unusual to find that "my brother won't agree to divide the inheritance", leaving the succession indefinitely at a standstill.
- Valuation of assets: One of the heirs may not be in accordance with the valuation of a particular asset (for example, they believe the family home is worth more than the figure given). These differences make it difficult to reach an equitable distribution.
- Use of the family home: One sibling wants to keep the parents' home while another prefers to sell it, or worse, one moves into the jointly owned property without the others' consent. Indeed, the Supreme Court recently had to order the eviction of an heir who had unilaterally occupied the family home before the estate had been divided. The Supreme Court made clear that no co-heir may make exclusive use of a jointly owned estate asset to the exclusion of the others while it remains undivided.
Poor communication is often at the root of many of these conflicts. There may be verbal promises made by the deceased that were never put in writing, sibling rivalry over perceived preferential treatment, or simply a lack of trust. Whatever the cause, the reality is that these disputes can drag on for years or even decades if steps are not taken to resolve them. Indeed, because there is no statutory time limit for requesting the partition of an estate (the right to do so does not expire), some inheritances remain undivided for decades and can even pass to the next generation without ever having been settled.
Heirs in Dispute in Catalonia: Forced Inheritance Rights, Wills and Legal Specifics
Each autonomous community in Spain has its own succession rules, and Catalonia has a specific Catalan civil law framework governing inheritance. This introduces particularities that can shape disputes between heirs:
- Forced inheritance rights (legítima) in Catalonia: This is perhaps the most common source of conflict in our practice. Catalan forced inheritance law grants the deceased's children the right to receive, collectively, one quarter of the estate, regardless of the testator's wishes. In other words, even if the parent left the bulk of the estate to someone else, the descendants can claim at least 25% of the total inheritance. This reduced forced share (under Spanish common civil law, the children's forced share amounts to one third) can sometimes generate feelings of injustice or confusion among siblings. Our experience shows that sound lifetime succession planning, through a clear will or succession agreements, significantly reduces the risk of disputes.
- Disinheriting a difficult child: The Catalan Civil Code permits the disinheritance of a forced-share heir on strictly defined grounds (for example, a prolonged breakdown in the relationship attributable to the child). However, such cases frequently end in legal challenges brought by the disinherited party. If you are considering this course of action, it is essential to seek legal advice to ensure that the grounds are thoroughly justified and evidenced, so as to avoid future court battles.
- Co-ownership of inherited assets (proindiviso): It is common for several siblings to jointly inherit a property, land or other indivisible assets. In Catalonia, there is a specific judicial procedure for dissolving the co-ownership of inherited assets. A co-heir may apply to the court for a division: if the asset can be divided, it is partitioned physically; if it is indivisible, the court may award it to one of the heirs with compensation paid to the others, or order its sale and distribution of the proceeds. This provides a clear route to breaking a deadlock, although ideally the siblings would first reach an agreed solution, for example, one sibling wishing to keep the property buying out the others' shares.
In summary, the Catalan legal framework provides tools to protect the rights of all heirs. At the same time, it imposes obligations: for example, respecting the statutory minimum inheritance (legítima) of children and, importantly, from 2025 onwards, attempting to reach an agreement before resorting to litigation, as we shall explain below. Understanding these rules is essential when dealing with a complex inheritance in Catalonia. At Iusfamilia, we hold specialist qualifications in Catalan inheritance law (our lawyers have postgraduate degrees in Catalan civil law and a master's in succession law), which allows us to anticipate and navigate these particularities in our clients' best interests.
What to do when an heir refuses to distribute the estate?
This is one of the most common questions in contentious inheritance cases: "My brother won't sign to divide the estate, can I force him to?". Spanish law is clear: no heir can be compelled to leave an estate undivided indefinitely. Any heir has the right to request the partition of the estate at any time. In other words, if a co-heir insists on blocking the distribution, the others can take legal steps to break the deadlock.
Amicable solutions vs. litigation: mediation as the key to resolving contentious inheritances
An impartial mediator can help heirs reach an amicable agreement, sparing all parties the strain of court proceedings.
Until recently, when siblings could not reach an agreement there were only two options: going to court (through an estate division procedure) or pursuing family mediation. Since the entry into force of Law 1/2025 of 2 January, the balance has shifted decisively towards negotiated resolution: it is now mandatory to attempt a negotiated settlement before bringing a civil claim. In inheritance matters this is particularly significant, as the law itself recognises mediation as a valid form of prior negotiation. At Iusfamilia, being both qualified lawyers and accredited family mediators, this approach is in our DNA: we always explore the possibility of agreement first, both out of conviction and because it is now a legal requirement.
What does inheritance mediation involve? It is a voluntary and confidential process in which a neutral mediator helps the heirs to communicate and work together towards a solution. Unlike a judge, the mediator does not impose anything, they simply facilitate dialogue.
The benefits of mediation are clear: it is faster, less costly, both financially and emotionally, and it preserves long-term family relationships. In fact, when siblings reach an agreement themselves, they tend to be far more satisfied than if a judge imposes a solution.

What if mediation does not work? In that case, the courts remain an option.
