An inheritance contract is often treated like a will, although its binding effect and formal requirements may go further. After death, the issue is therefore not only what the document says but also whether it was validly made and later brought to an end.
Sections 602 to 604 ABGB provide the statutory framework. This article explains how to check form, scope and withdrawal without treating one clause as a complete answer.

Define the binding scope
Not every sentence has the same contractual succession effect.
Classify termination
Withdrawal, mutual cancellation and a new will must not be confused.
Why form comes first
Why form comes first
An inheritance contract is not an informal family arrangement. Statutory form and personal participation decide whether a binding agreement exists at all.
In a dispute, the original, notarisation, supplements and the formation of the parties’ intent should be reviewed together. A copy with an unclear origin may not be enough.
Which statements are actually binding
Which statements are actually binding
The wording must show whether an appointment as heir or another binding arrangement was intended. Wishes, conditions and motives may have a different legal function.
The parties and their shares also matter. A later disposition can conflict only to the extent that it violates a valid binding arrangement.
How withdrawal differs from cancellation
How withdrawal differs from cancellation
Withdrawal requires a statutory or contractual basis. A unilateral statement is not automatically effective merely because the relationship later deteriorated.
Mutual cancellation, permitted withdrawal and revocation of a will are different acts. Their form and receipt should be recorded in the chronology.
Which records help in a dispute
Which records help in a dispute
The original, notarisation notes, supplements, cancellation letters and proof of receipt of later statements are important. Together they show the development of the binding intention.
Before challenging or defending the contract, read the entire document chain. Further succession updates are available through the firm newsletter.

| Question | First record | Next review |
|---|---|---|
| Check form | Probate proceedings | Secure the making form and the parties involved first. |

Inheritance disputes turn on the complete document chain. Broad assumptions about shares, value or liability often lead in the wrong direction.
Frequent questions
Inheritance contracts in Austria: form, binding effect and withdrawal
Is an inheritance contract stronger than a will? +
A valid inheritance contract can be binding. Its scope depends on form, content, parties and later statements.
Can an inheritance contract be revoked at any time? +
Not automatically. Withdrawal and cancellation have their own requirements under the law, contract and evidence.
Is a copy enough? +
A copy can be an important starting point. The full chain of instruments, supplements and later changes should be secured where possible.
