Auction of a building right: reversion clause and compensation calculation

Section 133 of the Austrian Enforcement Act permits enforcement by auction of a building right. The building right itself is therefore the auction object. Under section 6 BauRG, the building acquired or constructed under the right is accessory to that right. This differs from an auction of land carrying a separate superädifikat.

Section 3 BauRG limits the original term to at least ten and at most one hundred years. For a buyer, the original term says little if a substantial part has already elapsed. The first calculation should therefore subtract the expected award date from the contractual expiry date.

Section 168 EO requires the information and conditions relevant to the auction to appear in the edict. The edict does not replace reading the agreement. It shows which documents must be followed through in the particular court file.

Under section 9(1) BauRG, the building passes to the landowner when the building right expires. Statutory liens and preferential rights attached to the building right pass to the land once the right expires. The buyer is therefore dealing with a different legal position from perpetual ownership of the land.

In the absence of another agreement, section 9(2) BauRG provides compensation equal to one quarter of the existing building value. This is the statutory default. The building-right agreement may set another calculation or another share. The agreement is therefore the first document to examine when the auction file or a description refers to a Heimfallklausel.

The statutory default can be written as a simple working formula: compensation equals one quarter of the existing building value. Existing building value is not automatically the market value of the land, the highest bid or historic construction costs. Its assessment depends on condition, age, construction and valuation assumptions. A reliable figure requires the valuation report and agreement to be reviewed together.

A building right can have a different economic profile at the start of its term than shortly before expiry. The buyer should compare expected use during the remaining term with financing, maintenance, ground rent and required adaptations.

Ground rent is an ongoing charge of the building-right holder. Check amount, due date and arrears against the agreement and court documents. Section 4(2) BauRG permits an agreement on expiry for ground-rent default only where the ground rent has remained unpaid for at least two consecutive years. That requirement cannot be inferred from one payment statement alone.

At least four figures should remain separate in the bid limit: capital paid for the bid, ongoing payments, use until expiry and possible compensation when the right expires. The bid planning tool can structure the calculation. It does not replace review of the building-right agreement.

The German term Heimfallklausel may be used in an agreement, an edict or a description for different purposes. Section 4(1) BauRG provides that a building right cannot be limited by a resolutory condition. This protects the term from arbitrary early termination. The agreed expiry and the consequence under section 9 BauRG remain separate questions.

Check whether the wording describes the ordinary expiry of the right, a compensation rule, a ground-rent default or another contractual consequence. These categories lead to different legal questions. The buyer should not infer early termination or a particular payment from the label alone.

Section 189(2) EO generally excludes warranty for incorrect statements in the edict or documents communicated with it. Unclear information about expiry, ground rent or compensation therefore belongs on the list of open points before bidding.

Arrange the records in a fixed order. Start with the current auction edict and the complete building-right agreement. Add the separate building-right entry, valuation report, amendments, ground-rent statements and notices of changes to the building.

Mark the same key data in every document: parties, land, building, start date, expiry date, ground rent, due date, compensation and any consent requirements. Different spellings or dates must be explained. The valuation report review helps classify condition and building value. The article on auction edict and conditions provides the wider file review.

If the file does not contain a clear version of the agreement, keep the bid decision open until the term and compensation can be clarified. This is a direct economic consequence of an unclear remaining term.
