Divorce from a spouse with a mental illness in Poland – what you need to know

Wedding vows speak of love “in sickness and in health.” Mental illness puts that promise to an exceptionally difficult test. People who come to us with this situation have usually spent years trying to keep the marriage together – and only after exhausting every other option do they start asking whether divorce is possible. The answer is yes. But the path is more complex than in a straightforward divorce case.

Is a spouse’s mental illness a barrier to divorce?

No – a spouse’s mental illness does not in itself prevent a divorce from being granted. The condition that must be met remains the same as in any divorce case: it must be established that the marriage has broken down completely and permanently within the meaning of Article 56 § 1 of the Family and Guardianship Code (Kodeks rodzinny i opiekuńczy) – meaning that the spiritual, physical, and economic community between the spouses has ceased. Where the breakdown is genuine and irreversible, the court may grant a divorce even where one of the parties is living with a serious mental illness.

Mental illness is, however, a circumstance the court takes into account in a broader context – when assessing fault, when examining the negative conditions for divorce, and when considering whether granting a divorce would be contrary to the principles of social coexistence. This means that every such case requires an individual approach.

Can a mentally ill spouse be found at fault for the breakdown?

This is one of the most frequently asked questions – and the answer is not straightforward. Fault in the breakdown of a marriage presupposes, as a general rule, deliberate and voluntary breach of marital obligations. A mentally ill spouse may act in ways that damage the marriage but which they do not fully control and of which they may not be fully aware. In such cases, fault in the legal sense is difficult to establish.

Courts have accepted, however, that mental illness is not an automatic shield against a finding of fault. A mentally ill spouse may be found at fault for the breakdown in several situations. First, where they consciously and deliberately refuse to seek treatment despite being aware of their illness and its impact on the family. Second, where they deliberately concealed their illness before the marriage was contracted – which may also provide grounds for annulment of the marriage. Third, where their conduct, even if connected with the illness, involved conscious and deliberate violation of marital duties.

The court examines the specific circumstances of each case. The mere fact that a mental illness appears in the medical history does not determine the question of fault either way.

When can the court refuse to grant a divorce?

Even where the breakdown of the marriage has been established, the court may dismiss the petition where one of the negative conditions under Article 56 § 2 of the Family and Guardianship Code applies. In cases involving a mentally ill spouse, two of these conditions are particularly relevant.

The first is the welfare of the parties’ minor children. Where granting the divorce would seriously harm the children’s welfare, the court may refuse. A parent’s mental illness is a circumstance the court examines carefully in this context.

The second is the principles of social coexistence (zasady współżycia społecznego). The court may refuse a divorce where granting it would be contrary to these principles. The Supreme Court, in its judgment of 4 February 1985 (reference IV CR 557/84), addressed situations in which a spouse’s illness does not threaten the stability of the marriage or the welfare of the children – and in such circumstances, a refusal to grant the divorce may be justified.

This does not mean that every case involving a mentally ill spouse will fail. Courts assess the overall picture – the severity of the illness, its impact on family life, the situation of the children, and the actual state of the relationship between the spouses. The case is not lost in advance – but it requires careful preparation.

The role of a psychiatric expert in the proceedings

In cases where one spouse’s mental health is a significant factor, the court almost invariably appoints a forensic psychiatric expert. The expert assesses the spouse’s mental condition, their capacity to understand their own actions and their consequences, and sometimes their ability to participate in the court proceedings at all.

The expert’s opinion can be decisive on the question of fault. Where the expert finds that the spouse’s conduct resulted from a condition that prevented them from acting consciously and voluntarily, the court may decline to attribute fault. Conversely, where the expert confirms that the spouse was aware of their illness and deliberately refused treatment, a fault finding remains possible.

What if the ill spouse cannot participate in proceedings independently?

Where the ill spouse’s mental condition is severe enough that they are unable to manage their own affairs – for example, where they have been legally incapacitated (ubezwłasnowolniony) or where incapacitation proceedings are underway – the court appoints a procedural guardian (kurator procesowy) to act on their behalf in the proceedings. The appointment of a guardian does not block the divorce proceedings, but it significantly affects how they unfold.

In our experience, this is often the stage at which the greatest practical difficulties arise – and where early legal advice helps avoid costly procedural mistakes.

Practical guidance

If you are considering divorcing a spouse with a mental illness, several matters deserve particular attention.

Gather medical documentation – the history of treatment, diagnoses, and any refusals to engage with therapy or medication may be key evidence. Also collect documentation of the illness’s impact on family life and the children’s wellbeing.

Establish whether the spouse has been legally incapacitated or whether such proceedings are underway – this directly affects how the divorce case will proceed.

Consult a lawyer before filing, to assess whether any negative conditions exist that could block the divorce and how they can be effectively addressed.

FAQ

Does a spouse’s mental illness automatically mean divorce is impossible? No. Mental illness is not a barrier to divorce where the marriage has broken down completely and permanently. The court examines the overall circumstances, including any negative conditions that might prevent a divorce from being granted.

Can I seek a finding that my mentally ill spouse bears exclusive fault? It is possible, but only where their conduct leading to the breakdown was conscious and deliberate – for example, where they knowingly refused treatment or concealed their illness before the marriage. The illness alone is not a sufficient basis for a fault finding.

What if my ill spouse refuses to agree to the divorce? A spouse’s objection to the divorce does not block proceedings where the negative conditions under Article 56 § 2 of the Family and Guardianship Code do not apply. The court will consider whether granting the divorce would be contrary to the principles of social coexistence or to the children’s welfare.

Could the mental illness provide grounds for annulment rather than divorce? Yes – where the spouse was in a state that excluded conscious expression of will at the time the marriage was contracted, annulment may be possible under Article 12 of the Family and Guardianship Code. This is a separate legal institution from divorce, with different conditions and consequences. It is worth discussing with a lawyer which route is appropriate in the specific situation.

How long do these proceedings take? Cases involving a mentally ill spouse typically take longer than standard divorce proceedings, because of the need for a psychiatric expert’s report and sometimes the appointment of a procedural guardian. As a rough guide, proceedings of this kind can take from one to several years.

I am a foreign national – does Polish law apply to my situation? Where both spouses are habitually resident in Poland, Polish courts generally have jurisdiction and Polish law applies to the divorce. The rules described in this article – including the role of the psychiatric expert and the negative conditions for divorce – apply regardless of the parties’ nationality. If one spouse has been incapacitated by a court in another country, or if there are parallel proceedings abroad, the situation may be more complex and legal advice specific to the cross-border elements is strongly recommended.

Is there any alternative to divorce in cases of serious mental illness? Legal separation (separacja) is available as an alternative under Article 611 of the Family and Guardianship Code, with many of the same legal effects as divorce but without dissolving the marriage. This may be a relevant option in cases where the negative conditions for divorce are present but the parties wish to formalise their separation. Whether separation or divorce is the appropriate route depends on the specific circumstances.
