Receiving an inheritance should be an orderly process in which the wishes of a deceased person are fulfilled and their estate is passed on to their successors. In practice, however, many inheritances end up becoming a source of family conflict, legal disagreements and deadlocks that can drag on for years.
When a family member dies, it is not only assets, rights and obligations that are transferred, but also emotions, memories, financial expectations and, at times, pre-existing family conflicts. The combination of grief and the need to make decisions about the estate can create especially complex situations between siblings, relatives and other heirs.
For this reason, sound succession planning and having a lawyer for disputes between heirs from the outset can be decisive in protecting everyone’s rights, avoiding unnecessary confrontation and ensuring that the deceased’s wishes are fulfilled in accordance with the applicable law.
Key Takeaways
- Disputes between heirs mainly arise from disagreements over the valuation of assets, the distribution of the estate, interpretation of the will, or prior gifts.
- While the estate remains undivided, its assets belong to the estate community, and no heir may use them exclusively without the agreement of the others.
- Forced heirs are entitled to the forced share (legítima); in Catalonia this is a credit right (a quarter of the value of the estate), not a right to specific assets.
- If no agreement can be reached, options include mediation or judicial estate division proceedings.
- Accepting an inheritance subject to inventory limits the heir’s liability for any debts left by the deceased.
- Having a lawyer for disputes between heirs from the start helps protect rights, reduce emotional strain and preserve family relationships.
Why do disputes between heirs arise?
Inheritance disputes generally arise when heirs fail to reach agreement on one of the essential aspects of the succession: acceptance of the inheritance, valuation of the assets, administration of the estate, or the final distribution. Identifying these causes early with the help of a lawyer for disputes between heirs makes it possible to act ahead of time and prevent the disagreement from becoming entrenched.
The most common causes are:
- Lack of communication or trust between family members.
- Different expectations about the distribution.
- Disagreements over the value of properties, businesses or other assets.
- Different interpretations of the will.
- Conflicts over the use or management of shared assets.
- The existence of gifts made during the deceased’s lifetime.
- A sense of unequal treatment between siblings.
- Differences over how to take on debts or expenses linked to the estate.
In many cases, the problem does not arise solely for financial reasons, but from emotional issues, the perception that a family member received preferential treatment, or previously unresolved family situations.
Main problems when dividing an inheritance
Valuing and allocating assets
One of the points that generates the most disagreement is determining the value of the assets that form part of the estate and deciding how they should be divided.
Properties, family businesses, shareholdings and other assets can carry significant economic and emotional weight, which makes reaching agreement difficult.
To avoid conflict, it may be advisable to:
- Request independent professional valuations.
- Obtain objective market valuations.
- Analyse the different options for allocation.
When one of the heirs wishes to keep a specific asset, they may acquire the share belonging to the others through financial compensation, provided the parties concerned agree.
The inherited family home
The family home tends to be one of the assets that generates the most conflict between siblings.
While some heirs may want to sell it and split the proceeds, others may prefer to keep it for personal, sentimental or family reasons.
While the estate has not yet been divided, its assets remain part of the estate community and must be managed in a way that respects the rights of all co-heirs.
No heir may use a jointly owned asset exclusively to the detriment of the others, unless the parties agree otherwise or there is authorisation in accordance with the law.
In addition, expenses linked to the property, such as taxes, maintenance, repairs or utilities, can become another source of conflict if there is no proper coordination between the heirs.
When an heir blocks the inheritance
A common situation arises when one of the heirs refuses to sign documents, attend the notary or accept agreements on the distribution.
An heir’s refusal can make the process more difficult, but it does not mean the others must indefinitely accept a deadlock. In these cases, a lawyer for disputes between heirs can assess which legal mechanism is best suited to unblock the situation.
When no agreement is reached, those involved can turn to the legal mechanisms available, including judicial estate division proceedings, which allow the inventory to be drawn up, the assets valued and the distribution carried out in accordance with the law.
Inheritance rights and the main legal disputes
The forced share under Spanish common law
In regions where the common Civil Code applies, certain family members are considered forced heirs and are entitled to receive the forced share (legítima), unless there is a legally recognised and duly proven ground for disinheritance.
For children and other descendants, the forced share corresponds to a reserved portion of the estate under the rules set out in the Civil Code.
If an heir believes their forced-share rights have been infringed, they can bring the relevant legal actions to claim what they are entitled to.
The forced share in Catalonia
Catalonia has its own succession regime, governed by the Catalan Civil Code.
One of the main differences from common law is that the Catalan forced share has the nature of a credit right.
Children and other descendants are jointly entitled to receive a quarter of the value of the estate left by the deceased, except in cases provided for by law.
This means the person entitled to the forced share does not necessarily have a right to receive specific assets, but rather to claim the corresponding economic value.
For this reason, in Catalonia it is especially important to carry out proper succession planning through a will or other legally available tools, particularly where there is significant wealth or complex family structures involved.
Gifts made during the deceased’s lifetime
Gifts made before death can give rise to disputes when heirs believe that certain transfers of assets or money should be taken into account in the distribution.
Depending on the specific case, it may be necessary to examine issues such as:
- Whether collation of certain gifts applies.
- Whether a gift infringes forced-share rights.
- Whether certain lifetime dispositions should be reduced.
Each situation must be analysed individually in light of the applicable regulations.
Disinheritance
Disinheritance can only take place where the legally established grounds are met and must be properly recorded and justified.
When an heir is disinherited, they can challenge the decision if they believe the legal requirements have not been met.
For this reason, any decision of this kind requires proper planning and specialised legal advice to avoid future court proceedings.
Inheritances with debts, another common source of conflict
Accepting an inheritance means receiving both the assets and the obligations of the deceased.
For this reason, before accepting an inheritance it is important to review the full financial situation of the estate.
Where there are doubts about possible debts, one alternative may be to accept the inheritance subject to inventory, so that the heir’s liability is limited in accordance with the applicable law.
There is also the option of renouncing the inheritance where the costs or obligations outweigh the benefits it may bring.
What to do when heirs cannot reach an agreement?
When an inheritance dispute arises, there are several different ways to try to resolve it.
Negotiation and agreement between heirs
Whenever possible, reaching an agreement is the most advisable option.
Well-structured negotiation makes it possible to find solutions tailored to each party’s needs, such as:
- Agreed distribution of assets.
- Sale of certain assets.
- Allocation of properties to one of the heirs.
- Financial compensation.
- Agreements on the temporary use of jointly owned assets.
Mediation as an alternative for resolving inheritance disputes
Mediation is a particularly suitable tool for family conflicts arising from an inheritance. A lawyer for disputes between heirs with training in mediation can support this process, ensuring that any agreement respects the rights of all parties.
The loss of a loved one can bring a mix of emotions, memories, expectations and personal differences that make communication between heirs difficult.
In these cases, the intervention of a neutral mediator creates a space for dialogue where each party can express their interests and seek consensus-based solutions.
Mediation can help resolve issues such as:
- Disagreements over the distribution of assets.
- Valuation of the estate.
- Use or allocation of properties.
- Differences between siblings or family members.
- Compliance with the provisions of the will.
Its main advantages include:
- Greater speed compared with court proceedings.
- Lower financial cost.
- Greater control by the parties over the final outcome.
- The possibility of preserving family relationships.
Unlike court proceedings, where the final decision rests with a judge, in mediation it is the heirs themselves who actively take part in reaching an agreement.
Judicial estate division proceedings
When it is not possible to reach an agreement, it may be necessary to go to court.
Estate division proceedings make it possible to draw up an inventory of assets and debts, value them and carry out the distribution in accordance with the applicable law. Having a lawyer for disputes between heirs at this stage is essential to prepare the inventory and defend each heir’s interests.
Professionals such as a court-appointed estate distributor (contador-partidor) and expert valuers may take part in these proceedings to facilitate the formation of inheritance lots and the correct valuation of the estate.
Although this is a legally available solution for unblocking complex situations, it usually involves more time, financial cost and emotional strain.
The importance of planning an inheritance
Many inheritance disputes can be reduced through proper succession planning.
- Some preventive measures include:
- Drafting a clear, up-to-date will.
- Reviewing your financial situation periodically.
- Analysing the tax consequences of the succession.
- Planning the transfer of family businesses.
- Anticipating solutions for jointly owned assets.
- Appointing figures to facilitate the future management of the estate where appropriate.
In Catalonia, tools such as succession agreements (pactes successoris) can be especially useful for organising the transfer of assets in advance in certain cases.
In inheritance disputes, acting in time is key. Disagreements between heirs not only affect the distribution of the estate; they can also damage family relationships and create conflicts that, if not managed properly from the outset, can have consequences that are difficult to reverse.
Having a lawyer for disputes between heirs from the earliest stages of the conflict makes it possible to understand each party’s rights, weigh up the different options and define the most appropriate strategy for each case. Acting early favours the search for effective solutions, minimises the financial and emotional impact of the conflict, and makes it easier to reach agreements where they are viable. If agreements cannot be reached, it ensures a solid, effective defence of the client’s interests in court.

Frequently asked questions about disputes between heirs
Usually because the estate is undivided: it is not established what each heir will keep and there is no agreement on how to divide it. It can be resolved either out of court or through the courts.
No. No heir may use the inherited family home exclusively without the agreement of the other co-heirs.
It is the portion of the estate to which children or descendants are entitled and, failing them, the ascendants. In Catalonia it amounts to a quarter of the value of the estate’s assets at the time of the deceased’s death.
They can be formally required, before a notary or in court, to state whether or not they accept the inheritance; if they say nothing, it is understood that they do not accept it. If they block the division, judicial division of the estate can be requested.
Besides the costs, which are higher through the courts, in mediation it is the interested parties themselves who decide, whereas in court proceedings the judge decides.
If you accept it subject to inventory, only the estate’s assets are liable for the debts; if they are not enough to cover them, you do not have to pay anything out of your personal assets.
