Marriage Annulment in Austria: Grounds, Procedure, and Consequences

Marriage Annulment in Austria: Grounds, Procedure, and Consequences Marriage annulment in Austria explained: grounds for nullity (Ehenichtigkeit) and rescission (Eheaufhebung), court procedure, deadlines, and how it differs from divorce. Topics: Daily Life, .

Marriage annulment (Eheannullierung) in Austria is not the same as divorce. While a divorce terminates a valid marriage, an annulment declares that the marriage was never valid from the start because it violated the law at the time of conclusion. Austrian law distinguishes between two separate legal instruments: Ehenichtigkeit (nullity of marriage) and Eheaufhebung (rescission of marriage).

This guide explains the difference between nullity and divorce, the five grounds for declaring a marriage void under §§ 20–25 of the Austrian Marriage Act (Ehegesetz — EheG), the three grounds for rescission (§§ 33–45 EheG), applicable deadlines, and the legal consequences for property, children, and maintenance. The article draws on the Ehegesetz, Austrian court practice, and official clarifications from the Ministry of Justice.

Nullity vs. Rescission: Two Separate Legal Concepts

Austrian family law draws a sharp line between two forms of annulment. Understanding the difference is crucial because each has distinct legal effects.

Ehenichtigkeit (nullity of marriage) means the marriage is declared void from the beginning (ex tunc). The court establishes that the marriage never legally existed because fundamental legal requirements were violated at the time of the ceremony. The petition can be filed not only by the spouses but also by the public prosecutor (Staatsanwaltschaft).

Eheaufhebung (rescission of marriage) is the dissolution of a marriage at the request of a spouse whose consent was defective. Unlike nullity, rescission operates for the future (ex nunc) — just like a divorce. The marriage is considered valid until the court decision becomes final.

In practice, Eheaufhebung is more common than Ehenichtigkeit, but both are far rarer than standard divorce. As Finanz & Recht notes, rescission is the “fourth way to end a marriage” alongside death, divorce, and nullity.

When a Marriage Is Void: The Five Grounds for Nullity

Under § 20 EheG, a marriage can be declared void only in the cases explicitly listed in the law. The list of five grounds is exhaustive.

Form defects (§ 21 EheG) — a marriage is void if the ceremony did not follow the formal requirements of § 17 EheG. However, the law provides a cure: if the spouses lived together for five years (or at least three years before one spouse’s death), the marriage is retroactively considered valid.

Lack of capacity (§ 22 EheG) — a marriage is void if one spouse was legally incapacitated (geschäftsunfähig), unconscious, or suffering from a temporary mental disorder at the time of marriage. Important exception: after the condition ends, the spouse may confirm the marriage, making it valid from the start.

Sham marriage (§ 23 EheG) — the so-called Namensehe (marriage for a surname) or Staatsangehörigkeitsehe (marriage for citizenship). If the marriage was concluded exclusively or predominantly to obtain a surname or citizenship, without intent to establish a marital community, it is void. Only the public prosecutor can file a petition under § 23.

Bigamy (§ 24 EheG) — a marriage is void if one spouse was already in a valid marriage with a third party at the time of the ceremony (Doppelehe).

Consanguinity (§ 25 EheG) — marriage between direct-line relatives or between full or half siblings is prohibited and void.

The grounds for declaring a marriage void are exhaustive. No violations other than those expressly listed in §§ 21–25 EheG may result in nullity.

Rescission of Marriage: When a Spouse Can File

If a marriage is formally valid but one spouse entered it under a defect of will, the law grants the injured party the right to seek rescission (§§ 33–45 EheG). Unlike nullity, only the affected spouse can file — the one whose free will was compromised.

Error (§ 35 EheG) — a spouse may seek rescission if they were mistaken about personal qualities of the other spouse, of such a nature that, had they known the truth, they would not have married. Examples include concealment of a serious illness, infertility, a criminal record, or a mental disorder. Crucially, the error must concern personal qualities, not financial status or social standing.

Fraud (§ 36 EheG) — arglistige Täuschung. If one spouse deliberately deceived the other about circumstances that could have prevented the marriage, the deceived party may seek rescission. Examples include false information about religion, marital status, or intention to have children.

Duress (§ 37 EheG) — a marriage concluded under Drohung (threat) may be rescinded. The threat must be real and aimed at suppressing free will. Rescission is not possible if, after the threat ceased, the spouse’s conduct indicated a wish to continue the marriage.

Filing Deadlines for Rescission

The key limitation for Eheaufhebung is a one-year preclusive period. Under § 35(2) and § 36(2) EheG, the petition must be filed within one year of the spouse discovering the error or fraud. For duress (§ 37(2)), the deadline runs from the moment the threat ceases.

Missing this deadline means the right to rescind the marriage is lost irrevocably — even if the grounds were valid. Exception: if the spouse was prevented from filing (e.g., imprisoned or abroad without communication), the deadline may be suspended.

For nullity (Ehenichtigkeit), the one-year deadline does not apply — a petition can be filed at any time. However, under § 21 (form defects), if the spouses lived together for five years, the marriage becomes valid.

Court Procedure: How to File for Annulment

The annulment process begins with filing a petition (Klage) with the district court (Bezirksgericht). Jurisdiction is determined by the respondent’s domicile or, failing that, the last joint habitual residence of the spouses. If neither applies, the Bezirksgericht Innere Stadt Wien handles the case.

Required documents:

• Marriage certificate (Heiratsurkunde)
• Evidence supporting the grounds for annulment (medical reports, correspondence, witness statements)
• Expert opinions if necessary (e.g., psychiatric evaluation for § 22)

For nullity cases, the court may initiate proceedings ex officio — if it becomes aware of a violation affecting public interests (e.g., bigamy). The public prosecutor may also file a petition under § 23 (sham marriage).

The proceedings follow civil procedure rules (Zivilprozessordnung). The typical duration is 3 to 12 months, depending on complexity.

As the European e-Justice Portal explains, Austrian courts have jurisdiction if either spouse is an Austrian national, if the respondent is habitually resident in Austria, or if the petitioner is resident in Austria and both spouses had their last joint habitual residence there.

Consequences: Property, Children, and Maintenance

The consequences differ depending on the type of annulment.

With Ehenichtigkeit (nullity), the marriage is considered never to have existed:

• Property is divided not under marriage law (§§ 81–98 EheG) but under general civil law — each spouse takes back what they contributed, and jointly acquired assets are divided under ABGB rules on simple partnerships.
• Surname — a spouse who changed their name may keep it but must be informed of the legal implications.
• Children — those born in such a marriage are considered legitimate (ehelich). Their rights are fully protected.

With Eheaufhebung (rescission), the consequences are identical to divorce:

• Property division follows §§ 81–98 EheG. Jointly acquired assets are split equally unless a marriage contract provides otherwise.
• Maintenance (Unterhalt) — the former spouse may claim support if unable to provide for themselves. The rules are the same as for divorce.
• Pension rights — pension splitting applies for contributions made during the marriage.

Crucially, Eheaufhebung has no retroactive effect. All legal consequences that arose during the marriage (such as acquired citizenship) are preserved.

Annulment vs. Divorce: Why Choose One Over the Other

Many wonder why pursue annulment when divorce is simpler. The answer depends on the circumstances.

Divorce (Scheidung) is available in three forms: fault-based (§ 49 EheG), after three years of separation (§ 55 EheG), and by mutual consent (§ 55a EheG). Divorce terminates a valid marriage from the moment the decision takes effect.

Annulment (Ehenichtigkeit) establishes that the marriage was never valid. For some, this has moral, religious, or legal significance:

• For Catholics — the Church does not recognise divorce but may recognise nullity. While civil and Church annulment are separate procedures, a civil court ruling may be considered by a Church court.
• For sham marriages — only annulment through the public prosecutor can invalidate a marriage concluded without intent to form a family.
• For bigamy — the second marriage can only be annulled, as it was illegal from the start.
• For inheritance — with nullity, a spouse who knew about the defect may lose inheritance rights; with divorce, inheritance is automatically excluded after the divorce.

In practice, Austrian courts handle no more than 100–200 annulment cases annually, while divorce cases exceed 15,000 per year. Annulment remains an exceptional remedy.

As noted by vastenburg.at, if a marriage has irretrievably broken down, divorce is usually the appropriate path. Annulment is reserved for cases where the marriage was defective from the start.

Frequently Asked Questions

Can I get my marriage annulled if I simply changed my mind after the wedding?

No. “Changing your mind” is not a valid ground for annulment. If you have simply become disappointed in the marriage, divorce is the only option.

Does marriage annulment affect a residence permit?

With Ehenichtigkeit — yes. If the marriage is declared void for sham purposes (§ 23 EheG), this can lead to revocation of the residence permit obtained through that marriage. With Eheaufhebung, the residence permit is generally preserved if the marriage was genuine.

Can a Church annulment replace a civil one?

No. Church and civil annulment are independent procedures. A Church court ruling has no legal force under Austrian state law. You must go through a separate civil procedure.

How much does a marriage annulment cost in Austria?

Court fees depend on the value in dispute (Streitwert). Expect approximately €500 to €2,000 in court fees plus legal representation costs.
