Partition action: when a co-owner receives no further compensation

You are registered as a co-owner in the land register. Yet when the property is divided, you are to receive neither land nor money. Can that be lawful?

A decision of the Austrian Supreme Court shows that this can happen in certain circumstances. What matters is whether you previously received part of the jointly owned property and agreed that its value would count towards your share in a later division.

The case concerned four siblings and an agreement made in 1984. More than 40 years later, that agreement determined that the brother left the co-ownership without any further payment.

1. What is a partition action?

Where several people own a property, any co-owner may generally seek to end the co-ownership. If the parties cannot agree, they may bring a partition action.

There are two main routes. In a division in kind, the jointly owned property is divided, for example into separate plots. Condominium ownership may also be created in suitable buildings. If a division is impossible or would substantially reduce the value, the court may order an auction and distribute the proceeds.

In a division in kind, each co-owner should generally receive a portion that corresponds to their share in value and character. Earlier agreements may affect what a person is still entitled to receive.

2. What happened in the four siblings’ case?

A mother and her four children jointly owned several properties. In 1984, the mother held one third and each child held one sixth.

At the time, the eldest son received a plot from the jointly owned land. He intended to build a house on it and became its sole owner. All parties agreed that its value would be credited against his share in a later division in kind. The agreed valuation date was the date of that later division.

The brother retained his one-sixth interest in the remaining property. The mother later transferred her own share to the three daughters alone.

When the dispute arose, the sisters sought to end the existing co-ownership and take over the remaining properties together, one third each. Their brother was to receive no additional land or money. Under the agreed calculation, the plot he had previously received was already worth more than his total entitlement.

The Austrian Supreme Court confirmed the outcome in its decision of 1 October 2026, 5 Ob 103/26x.

3. Why did registration in the land register not entitle him to another payment?

The brother was still a co-owner. His registered share, however, did not guarantee that he would receive anything further when the property was later divided.

The family had agreed in 1984 to take the transferred plot into account in the later division. In economic terms, the brother had already received part of the property in advance. That value could cover his entire entitlement.

A previous transfer alone is insufficient. The decision turned on the specific agreement linking the earlier transfer to the later division in kind. The other co-owners cannot simply impose such a credit unilaterally after the event. This also differs from crediting previous gifts under inheritance law. The case concerned an agreement among living co-owners about their jointly owned property.

4. How is a previous allocation credited?

A simplified example using round numbers illustrates the method used in the case. The agreement determines which calculation applies in another case.

• The plots still held jointly are worth €1,200,000.
• The plot transferred earlier is valued at €300,000 under the agreement.
• The combined value is €1,500,000.
• The recipient’s one-sixth share of that value is €250,000.

Because the recipient already received a plot worth €300,000 for these purposes, the calculated entitlement is fully covered. The recipient therefore receives nothing further in the later division.

The order matters. First add the value of the earlier plot to the value of the remaining property. Then calculate the share. Finally, account for what the co-owner already received. Dividing only the remaining plots and subtracting the full value of the earlier plot would give the wrong result. One sixth of €1,200,000 is €200,000. After subtracting €300,000, the recipient would be €100,000 below zero instead of €50,000 below zero, to their disadvantage.

5. Can the other co-owners retain the property jointly?

In this case, the remaining plots did not have to be split into three separate portions. The sisters could form a new co-ownership and retain the remaining property jointly.

The sisters’ agreement to the arrangement and the protection of their brother’s rights were material. His earlier agreement to the credit and the fact that his entitlement was already covered were decisive. His objection to the arrangement alone could not prevent the sisters from holding the property jointly.

This does not give a majority a general right to exclude a co-owner. The validity and interpretation of the agreement, and the applicable property value, may still be disputed.

6. Must any excess value be repaid?

In the example, the value of the earlier plot exceeds the calculated share by €50,000. This does not automatically make that sum repayable.

The Supreme Court decided that the co-owner could leave without a further allocation or payment. It did not decide whether he was obliged to repay any excess.

Repayment requires a separate legal basis. An agreement should therefore make clear whether the credit only reduces further entitlements or whether an excess must also be repaid.

7. Which property value applies?

Land values can rise or fall substantially over the years. Whether the land can be built on may also make a significant difference. The agreement should therefore specify as clearly as possible the valuation date and the condition in which the land is to be valued.

The siblings had agreed to use the land value at the time of the later division in kind. The value in 1984 was therefore not carried forward unchanged.

How to treat a house subsequently financed by the recipient is a separate question. Rezoning, encumbrances and the recipient’s investments may also matter. The Supreme Court did not lay down a general rule for all later zoning changes in this decision.

8. Which documents should you have reviewed?

When a property is to be divided, the older agreements are particularly important alongside the land register extract. A transfer from decades earlier can still be decisive.

The following documents are especially useful for an initial review:

• The current land register extract and records of previous ownership shares.
• Sale, gift, transfer and partition agreements, particularly for previously transferred plots.
• Agreements and correspondence on what is to be credited in a future division.
• Existing valuation reports and records relating to buildings, zoning, encumbrances and investments.
• Any partition claim already served, with its attachments.

If a share has since been sold, gifted or inherited, it is also necessary to establish who is bound by the earlier agreement today. In particular, a buyer cannot simply be assumed to take over all the seller’s personal obligations.

Anyone transferring a plot within the family today should therefore agree how it is to be treated in a future division. This includes clear provisions on valuation, any excess and subsequent changes of ownership.
