Disinheritance and Exclusion from Inheritance

Michał Sochański, 21.01.2026

Disinheritance and exclusion from inheritance are legal institutions in inheritance law that allow for the deprivation of inheritance rights, even though the person to whom they apply formally belongs to the circle of heirs. Other cases are discussed in the article: Renunciation of Inheritance and Other Cases When a Potential Heir Does Not Inherit.

I encourage you to explore my other posts on inheritance law:

 

In this article, you will learn:

 

What Is Disinheritance?

Disinheritance means depriving a person entitled to a reserved portion of their right to receive it, as declared by the testator.

It is often confused with the so-called negative will, where the testator deprives an heir of their share in the estate but does not completely exclude them by taking away their right to the reserved portion, which they can still claim. Disinheritance specifically fulfills this function.

 

What Is the Reserved Portion?

 

The reserved portion (zachowek) is a legal institution designed to protect the closest relatives of the testator.

It ensures that descendants, the spouse, and parents of the testator, who would be entitled to inherit under statutory law, receive half of the value of their statutory inheritance share. This increases to two-thirds if the entitled person is permanently unable to work or if the entitled descendant is a minor.

You should know that descendants include all direct offspring of the same person: children, grandchildren, great-grandchildren, etc.

If the entitled person does not receive their reserved portion through a gift, inheritance appointment, or a legacy, they have a claim for payment against the heir to cover the shortfall.

This claim is pursued by filing a lawsuit with the court in the last habitual residence of the deceased. If this cannot be determined within Poland, the lawsuit is filed in the jurisdiction where the estate or part of it is located.

 

When Is Disinheritance Possible?

Disinheritance is only possible in cases specified in the Civil Code. It can be applied to a person entitled to the reserved portion if they:

  • Persistently act contrary to the principles of social coexistence against the will of the testator,
  • Commit an intentional crime against the life, health, freedom, or dignity of the testator or their close relatives,
  • Persistently fail to fulfill family obligations toward the testator.

 

What Is “Persistent Behavior Contrary to the Principles of Social Coexistence”?

This involves behavior by the heir that violates generally accepted norms of proper conduct and deserves societal condemnation. It must be of a negative nature, grossly breaching moral principles. Examples include a dissolute lifestyle characterized by criminal activities, alcoholism, drug addiction, gambling, or neglect of family welfare.

However, such behavior does not constitute grounds for disinheritance if the testator accepted it, for instance, by knowingly benefiting from the proceeds of crime, such as money or property.The behavior must also be persistent.

 

What Does “Persistence” Mean?

Persistence refers to prolonged misconduct by the heir or repeated improper behaviors, not necessarily of the same type.

 

What Are Intentional Crimes Against Life, Health, or Freedom and Gross Insults to Honor?

“Intentionality” in crimes involves the commission of a felony or misdemeanor in two forms:

  • Direct intent, where the perpetrator deliberately seeks to commit the crime,
  • Eventual intent, where the perpetrator foresees the possibility of committing the prohibited act and accepts it.

Common crimes against life, health, or freedom include:

  • Battery,
  • Causing grievous bodily harm,
  • Inflicting bodily injury,
  • Failing to render aid in danger,

A gross insult to honor occurs when the heir insults or slanders the testator.

 

Failure to Fulfill Family Obligations

Under the provisions of the Polish Family and Guardianship Code, every family member is subject to a series of duties that must be fulfilled to ensure the family’s proper development. These duties include maintaining family bonds, mutual support, and providing care and assistance, for example, due to age, health, or life circumstances.

For an heir’s behavior in failing to fulfill these obligations toward the deceased to justify disinheritance, it must be clearly reprehensible, meaning it results from their evident fault and stems from circumstances solely attributable to that person. Examples of such behavior include:

  • Frequently initiating conflicts with the deceased,
  • Making unwarranted and hurtful accusations against the deceased,
  • Forcing the deceased out of their home,
  • Failing to participate in the deceased’s life, such as visiting them or showing interest in their affairs.

It should be emphasized that failing to visit the deceased, if justified by grievances against them—even if it lasted for years—cannot be considered persistent failure to fulfill family obligations. Similarly, if the deceased neglected family contacts, they cannot use this as grounds to disinherit their closest relatives.

Who Can Be Disinherited?

Disinheritance may apply to:

  • Descendants, including the testator’s children, grandchildren, great-grandchildren, etc.,
  • Spouses, and
  •  Parents.

It cannot be applied to any other individuals.

 

How Can Disinheritance Be Carried Out?

Disinheritance can only be effected through a will. It occurs when the testator includes an appropriate declaration of intent in the will. It is important that the reason for disinheritance is explicitly stated, described, and justified in the will.

Disinheritance takes effect upon the opening of the estate, i.e., the death of the testator. Until then, it can be revoked if the relationship between the testator and the heir improves.

Disinheritance can be total or partial. Partial disinheritance results in depriving the heir of only part of the reserved portion. However, it is only valid if the reason for its application exists at the time the will is made. The absence of such grounds renders the disinheritance ineffective, and it cannot be rectified by the subsequent emergence of a reason. For instance, disinheritance cannot be conditional on future events, such as the heir developing a gambling addiction or neglecting family matters. However, it is permissible to specify that disinheritance will cease to have effect if, for example, an alcoholic son undergoes appropriate rehabilitation.

Disinheritance is not final—the testator can destroy, change, or revoke the existing will at any time before their death.

 

What Are the Legal Consequences of Disinheritance?

The legal effect of disinheritance is that the heir is deprived of both their direct share of the estate and the right to the reserved portion.However, the descendants of the disinherited person retain their right to the reserved portion, even if the disinherited individual outlives the testator.

 

When Is Disinheritance Not Possible?

According to current regulations, the testator cannot disinherit someone entitled to the reserved portion if they forgave their behavior before drafting the will.

If the testator lacked legal capacity at the time of forgiveness, it is only valid if done with sufficient discernment.

Interestingly, the law does not specify the form in which forgiveness must be expressed. It can be verbal, although written form is preferable for evidentiary purposes.

 

What Is Exclusion from Inheritance?

An heir can be excluded from inheritance in two ways:

  • Through a will, or
  • Through court proceedings.

 

Exclusion from Inheritance in a Will

Exclusion from inheritance in a will occurs when the testator omits certain individuals from the will, thereby depriving them of a share in the estate. This is known as a “negative will,” as mentioned earlier in this article. Importantly, the testator does not need to provide reasons for this decision. However, such exclusion does not remove the right to the reserved portion. This means that an excluded heir can still claim the reserved portion from the estate.

 

Exclusion from Inheritance Through Court Proceedings

Exclusion from inheritance through court proceedings is a specific tool provided for in Article 940 of the Civil Code. It applies exclusively to the deceased’s spouse and only under specific circumstances.

According to this legal provision, a spouse is excluded from inheritance if:

  • The testator filed for divorce or separation based on the spouse’s sole fault, and
  • The claim was justified.

Both conditions must be met simultaneously at the time of the opening of the inheritance.

Exclusion of a spouse from inheritance does not occur automatically; it requires a court ruling. This can only be achieved through a separate, specifically initiated proceeding by filing a lawsuit. This is because the death of the testator, as the plaintiff in divorce or separation proceedings, results in the automatic dismissal of the case by the court.

It should be noted that if the testator filed a petition or response to a petition requesting a ruling on the spouse’s fault but later changed their stance and requested a no-fault divorce ruling, there will be no grounds for excluding the other spouse from inheritance.A court ruling excluding a spouse does not happen automatically merely because the testator filed for divorce or separation.

The court must first conduct thorough evidence proceedings to establish beyond a reasonable doubt that:

  • There was a permanent breakdown of marital life (for separation) or a complete and irretrievable breakdown (for divorce),
  •  There are no negative grounds for granting a divorce,
  • The surviving spouse was solely at fault for the marital breakdown.

Only if all these conditions are met can the court issue a judgment excluding the deceased’s spouse from inheritance.

 

Who Can Request the Exclusion of a Spouse from Inheritance?

Any other statutory heir entitled to inherit alongside the spouse may request their exclusion. The defendant is the surviving spouse (heir) or, if they are deceased, their heirs.

 

What Is the Deadline for Filing a Lawsuit to Exclude a Spouse from Inheritance?

The deadline to file a lawsuit for excluding a spouse from inheritance is six months from the date the heir learned of the opening of the estate, but no later than one year from the opening of the estate (the testator’s death).

 

What Are the Legal Consequences of a Judgment Excluding a Spouse from Inheritance?

Regardless of whether the lawsuit is filed by one heir or several, a judgment excluding the spouse from inheritance affects all statutory heirs.

The legal consequence of such a judgment is that the spouse is excluded from inheritance as if they predeceased the testator. Consequently, they are also deprived of the right to the reserved portion.

 

FAQ

How can one disinherit a child (or other relative entitled to a reserved portion)?

Disinheritance of a child, spouse, or parents (as only these individuals can be disinherited) is done exclusively in a will. The testator must clearly state in the will the reason for disinheritance, which must be one of those listed in the Civil Code (e.g., persistent conduct contrary to the principles of social coexistence, a crime against the testator, failure to fulfill family obligations). This reason should be described and justified in detail.

What does it mean to disinherit someone?

Disinheritance means the testator, in their will, deprives their descendants (children, grandchildren, etc.), spouse, or parents of their right to a reserved portion (zachowek). This is a more far-reaching measure than simple omission in a will (a so-called negative will), because a negative will only deprives of a share in the estate but not the right to the reserved portion, which can still be claimed.

When is it possible to disinherit a child (or other person entitled to a reserved portion)?

Disinheritance of a person entitled to a reserved portion (child, spouse, parent) is possible only in three cases strictly defined in the Civil Code:

  1. When the entitled person, against the testator’s will, persistently acts in a manner contrary to the principles of social coexistence (e.g., leads a reprehensible lifestyle such as alcoholism, drug addiction, criminal activity).
  2. When the entitled person has committed an intentional crime against the life, health, or freedom of the testator or one of their closest relatives, or a gross insult to their honor.
  3. When the entitled person persistently fails to fulfill family obligations towards the testator (e.g., frequently starts arguments, is not interested in the testator’s life, does not provide help).

What is the reserved portion (zachowek) and who is entitled to it?

The reserved portion (zachowek) is a specific part of the value of an inheritance share that is due to the closest relatives of the testator, even if they were omitted in the will. Those entitled to the reserved portion are the descendants (children, grandchildren, etc.), spouse, and parents of the testator, who would have been called to inherit under statutory law. As a rule, the reserved portion amounts to half the value of the share they would have received under statutory inheritance. If the entitled person is permanently incapable of work or if an entitled descendant is a minor, the reserved portion is two-thirds of that share.

What specific behaviors can be grounds for disinheritance?

The grounds for disinheritance can be the following behaviors by a person entitled to a reserved portion:

  1. Persistent behavior contrary to the principles of social coexistence against the testator’s will: e.g., engaging in criminal activity, alcoholism, drug addiction, gambling, neglecting the family, provided the testator did not accept this and the behavior was long-lasting or repetitive.
  2. An intentional crime against the life, health, or freedom, or a gross insult to the honor of the testator or their close relatives: e.g., battery, causing grievous bodily harm, slander, defamation.
  3. Persistent failure to fulfill family obligations towards the testator: e.g., constantly starting arguments, making unjustified accusations, throwing them out of the house, lack of participation in the testator’s life, not providing care (unless this was due to the testator’s own fault).

How is disinheritance formally carried out?

Disinheritance can only be carried out in a will. The testator must include a declaration of intent to disinherit a specific person and precisely state the reason for disinheritance, which must comply with the statutory list of reasons and be evident from the content of the will. This reason should be described and justified in detail.

What are the main legal consequences of disinheritance?

The main legal consequence of effective disinheritance is depriving the disinherited person of their right to a reserved portion. This means they will receive neither a share of the estate nor any monetary equivalent as a reserved portion. However, it is important to remember that the descendants (e.g., children) of a disinherited descendant (e.g., the testator’s son) are entitled to a reserved portion from the original testator, even if the disinherited son outlived the testator.

In what situation will disinheritance be ineffective despite existing grounds?

A testator cannot effectively disinherit a person entitled to a reserved portion if they have forgiven them. Forgiveness can occur in any form (even verbally) but must happen before the will containing the disinheritance is made, or if the will already exists, forgiveness nullifies the effects of disinheritance. If the testator lacked legal capacity at the time of forgiveness, the forgiveness is effective only if made with sufficient discernment.

What is exclusion from inheritance, and how can it be applied to a spouse?

Exclusion from inheritance is a different institution from disinheritance. It can occur in a will (a so-called negative will, which deprives of a share in the estate but not the right to a reserved portion) or through court proceedings – the latter option applies exclusively to the testator’s spouse. A spouse can be excluded from inheritance by a court if the testator, before their death, had filed for divorce or separation due to the sole fault of that spouse, and this claim was justified. Both these conditions must be met jointly at the time of the testator’s death.

What are the legal consequences of a court judgment excluding a spouse from inheritance?

A final court judgment excluding a spouse from inheritance means that the spouse is treated as if they had not outlived the opening of the estate. This means they do not inherit from the deceased spouse either under statutory law or under a will (if they were named as a spouse), and they also lose the right to a reserved portion. Such a judgment affects all statutory heirs.
