When a building right expires, compensation for the building may become the relevant asset for the next stage of the transaction. For financing, the key question is whether mortgages or other rights in rem exist over the building right and whether those rights affect the compensation under section 10 of the Austrian Building Rights Act.

The rule applies only where the building-right holder is actually owed compensation under the law or the building-right agreement. The expiry of the building right therefore does not by itself answer whether compensation is due or how much must be paid. Both questions depend on the documents and the actual process.

This article focuses on the security position connected with the compensation claim. General issues concerning the purchase of a building right, ground rent, valuation or other consequences are mentioned only where they are needed to understand the security attached to the compensation.

01 Question 1

Is it documented when and why the building right expires?

The building-right agreement, land register and documents showing the end of the right should describe the same process.

All paths at a glance

Overview of all answers.

01

The expiry process is not documented well enough yet.

Collect the building-right agreement, amendments, land-register extract and documents showing why the right ends. The compensation claim can be assessed meaningfully once those documents describe the same process.

02

It is still unclear whether compensation is owed and how much it is.

Review the compensation clause and the statutory requirements. Payment should be based on a traceable position identifying the claim, amount and recipient.

03

Security rights have not yet been sufficiently included in the payment process.

Allocate every registered mortgage and other right in rem to the building right and the possible compensation claim. Then align the agreement, creditor information and escrow process.

04

The claim, security rights and payment route are prepared in a traceable way.

Once the reason for expiry, compensation claim, rights and payment route fit together, the central review is prepared. Keep the documents current until completion and check changes immediately before payment.

Building right expires: what section 10 provides

Section 10 of the Austrian Building Rights Act links the security effect to a specific condition: when the building right expires, the building-right holder must be owed compensation for the building under the law or the agreement. Only then do mortgages and other rights in rem over the building right extend to the compensation.

The provision describes a change in the secured object. The building right, which was the original point of attachment, comes to an end. The statutory link then moves to the compensation claim. The payment claim becomes the relevant reference point for reviewing the security position.

The rule also shows what it does not decide. It does not establish that compensation is payable in every case. It does not determine the amount or explain how a specific right must be enforced without reviewing the documents. Those questions remain tied to the law, the agreement and the actual facts.

A purchase or financing review should therefore begin by checking whether the agreement expressly deals with expiry and compensation. The existing article on buying a building right or superstructure covers the general classification of these special forms. The narrower question here is what happens to security when a compensation claim arises.

When the compensation claim becomes relevant

The claim must follow from the specific legal basis. Section 10 refers to compensation owed under the law or the building-right agreement. A party therefore should not infer a fixed payment from the mere expiry of a term without reading the agreement and the applicable statutory rule.

Review the agreed term, the precise reason for expiry and the provisions concerning the building. It is equally important to identify the intended payer. A clause may refer to the condition of the building, a method of calculation or specific evidence that must be provided. The wording determines which facts still need to be established.

The calculation also has to be read together with the agreement. Relevant matters may include the building described in the documents, alterations, the agreed valuation method and the relevant assessment date. A general estimate does not replace a document review where the amount is needed for the release or protection of financing.

For a purchaser of land or a building right, this preliminary issue is central. The purchase agreement should make clear whether an existing or expected compensation claim is transferred, assigned, set off or dealt with through escrow. Without that allocation, the object of the security remains unclear.

How mortgages extend to the compensation

Under section 10, mortgages and other rights in rem over the building right extend to the compensation where the statutory condition is met. For a mortgagee, the expiry of the building right therefore does not end the security review. The compensation claim must become the new point of attachment.

Start by identifying which rights actually exist over the building right. This requires the relevant land-register entries and the instruments that create or define the rights. The reference to other rights in rem means that the review cannot stop at one bank mortgage. Each relevant legal position needs its own allocation.

The security effect must not be confused with a free payment. If compensation is to be paid to the building-right holder, the payment route must take the affected rights into account. Which consent, statement or process is needed depends on the instruments, the type of right and the agreement.

The general land-register review remains a separate step. The land-register and encumbrances topic explains ownership, priority and charges. The compensation claim requires an additional review of how the specific right and the specific payment are connected.

Which documents must be read together

Begin with the current building-right agreement and all amendments. They should show the term, reason for expiry, compensation rule, building and possible calculation method. Side agreements and later changes cannot be ignored where they affect compensation or security.

Then compare the land-register position with the instruments. Relevant items include entries concerning the building right, mortgage instruments, priority information and indications of other rights in rem. An older extract may not show later changes, so the payment process needs a recent extract.

The file should also include documents about the end of the building right and the compensation. These may include notices of expiry, calculations, valuations, acknowledgements, payment demands and correspondence with creditors. They show whether the parties are working from the same claim and the same amount.

Where the building has been altered or extended, its description must match across the documents. The agreement, plans and calculation must refer to the same building state. The article on buying a demolition house and allocating building costs provides a related example of why the building condition should be described precisely.

How the purchase agreement and escrow protect payment

The purchase agreement should identify the compensation claim as precisely as possible. It should name the legal basis, the relevant building-right agreement, the building, the proposed calculation and the currently known amount or method. If the amount is still open, the agreement must allocate the next steps and the economic risk.

The payment recipient also needs a clear allocation. Compensation may be intended for the building-right holder while rights over the building right extend to the claim under section 10. The agreement should therefore state who is to pay, to whom payment discharges the obligation and which evidence must be available.

In an escrow process, the release conditions should reflect the security rights. The escrow agent needs the relevant agreements, current land-register information and details from the affected creditors. Releasing funds merely because the building right has expired or been deleted may bypass the statutory allocation of security.

The correct process depends on the facts. The topic on escrow and the purchase price sets out the general logic of escrow payments. The specific compensation claim and rights attached to it must still be established from the complete file.

Review fields

Which questions must fit together before payment

The table separates the claim, security and payment process.

Review fields when a building right expires and compensation is due
Review field Evidence Risk if incomplete
Expiry Agreement and reason for expiry Date and process are inconsistent
Compensation Statutory or contractual basis Claim and amount are assumed
Security Mortgages and other rights in rem A right-holder is overlooked in payment
Building Description, condition and calculation The amount relates to a different building state
Payment Recipient, evidence and escrow release Funds are released without coordinated security

The legal and economic result depends on the building-right agreement, land-register position and payment process.

Important: The expiry of a building right does not automatically mean that compensation can be paid to the former building-right holder free of security rights. Section 10 requires mortgages and other rights in rem connected with the compensation to be reviewed.

Common errors concerning security over compensation

A common error is assuming that every expiry automatically creates a fixed compensation payment. Section 10 links its security effect to compensation owed under the law or the agreement. That condition has to be established first.

It is also risky to equate the end of the building right with a payment free of charges. The original legal object may disappear while the security extends to the compensation. Deletion or expiry should therefore never be treated as a substitute for reviewing the payment.

Rights that are not perceived as a classic bank mortgage are often overlooked. Section 10 refers to mortgages and other rights in rem. The land register and the underlying instruments should be read in full so that every relevant position is considered.

An unclear description of the building can lead to an incorrect calculation. If the agreement, plans and payment statement refer to different states or parts of the building, the compensation claim cannot be allocated reliably. That inconsistency should be resolved before payment.

A useful sequence before payment

Start by establishing why the building right ends and when that event occurs. Then read the agreement, amendments, land register and instruments concerning mortgages or other rights in rem together. This is the point at which the relevance of a compensation claim for security can be assessed.

Next determine the claim, its calculation and the person responsible for payment. The parties should record which documents are still missing and who must provide them. If calculations differ, the basis must be settled before payment or set-off is prepared.

The security effect can then be translated into the payment route. The agreement, creditor information and escrow instruction should name the same recipient, conditions and payment scope. A clear record makes it easier to show that the statutory and contractual requirements were taken into account.

The expression change of the secured object is therefore a practical review signal. Ending the building right does not end the security question. The decisive points remain whether compensation is owed and which rights extend to it under section 10.

The term mortgage lien is explained in the glossary. The complete agreement and payment file should be reviewed for the specific transaction.

FAQ

Questions about building-right expiry and compensation

What happens to a mortgage when a building right expires? +

If the building-right holder is owed compensation for the building under the law or agreement, the mortgage extends to that compensation under section 10. The specific claim and security must be checked against the agreement, land register and instruments.

Does every expiry of a building right automatically create compensation? +

That cannot be assumed. Section 10 requires compensation to be owed under the law or the building-right agreement. The claim, payer and amount must be established for the individual case.

Do rights other than a bank mortgage need to be reviewed? +

Yes. Section 10 refers to mortgages and other rights in rem. The review should therefore include all relevant entries and instruments that may affect the compensation claim.

Which documents matter before payment? +

The key documents are the building-right agreement and amendments, current land-register extract, mortgage instruments, documents on other rights, expiry records, compensation calculation and payment arrangements. They should refer to the same building state and claim.
