The news that your own developer is insolvent hits buyers hard. Often considerable instalments have already flowed, but the apartment is not yet finished. Immediately the question arises what happens to the money already paid and whether the building project will be completed at all.

Unlike with an unsecured advance payment, the Developer Contract Act (BTVG) stands in the background of a developer contract. It prescribes a security for advance payments and names a trustee who monitors the instalments. How well you are protected in the event of insolvency therefore depends strongly on which security model your contract provides for.

This article shows what is to be reviewed immediately in the event of insolvency, how the individual security models work, what role the trustee plays in an emergency and how you register your claim in the insolvency proceedings. From a lawyer perspective, early and orderly action often decides the outcome here.

Classify your situation

Developer insolvent, how is your payment secured?

Answer one or two questions about the status of your purchase and the type of security. You will receive an initial classification regarding the protection of your advance payments under the BTVG.

01 Question 1

How far has your purchase progressed?

What matters is how your advance payments are secured and how far construction has progressed. The Developer Contract Act (BTVG) prescribes a security for advance payments, and its form co-determines your position in the event of insolvency.

All paths at a glance

Overview of all answers.

01

The first step is always to clarify the agreed security model and the status of the instalments.

Before your rights can be assessed, it must be clear how your advance payments are secured under the BTVG and how much you have already paid for which construction phase. Check the contract and instalment schedule to see whether a security registered in the land register with an instalment schedule, a bank guarantee or an insurance is agreed and who has been named as trustee.

Gather the contract, the instalment schedule, the payment receipts and the correspondence with the trustee. On this basis your position can be classified in the event of looming or opened insolvency.

02

With security registered in the land register and an instalment schedule, your position is tied to construction progress and to the registration.

Under the instalment schedule model you only pay once the respective construction phase is reached, and your prospective right is secured in the land register. In the event of insolvency it matters which entries exist in your favour and which instalments you have paid for which progress. The trustee releases instalments only where the confirmed construction progress is present.

Have the land register status, the instalment schedule and the trustee releases reviewed. This clarifies how far the payments you have already made are secured and which steps towards securing and completion are now due.

03

With contractual security, the reclaim is directed against the security provider, not only against the developer.

If your advance payment is secured via a bank guarantee or an insurance, you are entitled to a claim against the security provider in the security event. This security is meant to apply precisely when the developer no longer performs. Decisive are the exact content of the guarantee or insurance and the conditions and deadlines provided for therein.

Have the security document reviewed and clarify under which conditions and within which deadline the claim is to be asserted. Missed deadlines can endanger the claim, which is why swift action is important here.

04

If a BTVG-compliant security is missing, you should have your rights reviewed quickly and in a targeted way.

The BTVG prescribes a security for advance payments. If no permissible security can be recognised in the contract, or if payment was made in advance contrary to the law, your situation is particularly delicate, because the statutory protection is missing in the event of insolvency. Here it must be examined which claims exist against whom and how the possible damage can be limited.

Secure all documents immediately and have the contractual and statutory situation assessed. The earlier the weak point is identified, the sooner steps towards securing can still be taken.

What to review immediately in looming or opened insolvency

The first step is clarity about your own situation. Check how much you have already paid, which construction phase was reached for it and how your advance payments are secured under the BTVG. These three points determine how strong your position is and which steps make sense next.

Look in the contract and instalment schedule to see whether a security registered in the land register with an instalment schedule, a bank guarantee or an insurance is agreed and who was named as trustee. Contact the trustee, because they know the status of the instalments and releases and are a central point of information in an emergency.

Record all payments without gaps and assign every receipt to the respective construction phase. Avoid hasty further payments before the situation is clarified. An early legal assessment prevents you from taking steps in uncertainty that weaken your position.

How the BTVG secures advance payments

The core of the BTVG is the protection of advance payments. Because the buyer makes advance payment for a performance that is only to arise in the future, the law prescribes a security. It can be done contractually via a bank guarantee or insurance, in rem via a security registered in the land register together with an instalment schedule, or via a security by lien on the property.

Under the common instalment schedule model, payment is tied to construction progress: you only pay once the agreed construction phase is reached and confirmed. As a result, a corresponding value at the building always stands opposite your payment. The details of the instalment schedule are deepened in the glossary entry on the instalment schedule.

Which model applies in your case is stated in the contract and decisively determines your position in the event of insolvency. The overall overview of the security system and its risks is offered by the article on the risks of the developer contract under the BTVG.

Security in an emergency

BTVG security models in the event of insolvency

How well you are protected depends on the agreed security model. The overview classifies the common models and their effect in the event of insolvency.

Comparison of the BTVG security models regarding their mode of operation and effect in the event of insolvency
Security model Mode of operation Significance in the event of insolvency
Land register with instalment schedule Payment by confirmed construction progress, secured in the land register Instalments are coupled to the construction phase reached Position depends on registration and instalments paid
Bank guarantee Bank guarantees the repayment of the advance payment Claim is directed against the bank as security provider Applies independently of the insolvency proceedings under the guarantee conditions
Insurance Insurer secures the advance payment Claim is directed against the insurer Applies under the conditions of the policy and its deadlines
No permissible security Advance payment without BTVG-compliant security Statutory protection of the advance payment is missing Increased risk, the claim hits the insolvency estate

The overview does not replace a review of the individual case. Which security applies and how it works in the concrete insolvency case is to be assessed on the basis of the contract and the security document.

The role of the trustee in an emergency

Under the BTVG the trustee must be a lawyer or notary and is to be named in the contract. Their task is to administer the instalments and to release them only once the construction progress provided for is confirmed. This places an independent controlling body between your payment and the developer.

If the developer becomes insolvent, the trustee is a central point of information. They know which instalments have already been released and which have not yet been paid out. Amounts not yet released are tied to their purpose and may not flow to the developer without further ado, because the confirmed construction progress is missing. The function of the trustee is explained in the glossary entry on the trustee.

Contact the named trustee early and document the correspondence. Clarify which of your payments have already been released and which still lie with the trustee. This information is decisive for the assessment of your position.

Registering the claim in the insolvency proceedings

If insolvency proceedings are opened over the assets of the developer, the court appoints an insolvency administrator and issues an insolvency edict. It states the relevant deadlines, in particular the deadline for the registration of claims and the date of the examination hearing. Keep to the deadline stated in the edict so as not to endanger your claim.

Register your claim in writing with the insolvency administrator and enclose the contract, the instalment schedule and the payment receipts. At the examination hearing a decision is made on the registered claims, that is whether they are recognised or contested. A recognised claim is the basis for later participation in the proceedings.

Important is the distinction between secured and unsecured claims. A position secured in the land register or a claim from a bank guarantee or insurance stands independently of the general distribution in the insolvency. A mere monetary claim against the developer without security, by contrast, hits the insolvency estate. Which classification applies is to be reviewed carefully.

Common mistake: Letting the registration deadline stated in the insolvency edict lapse, or continuing to pay before the situation is clarified. Both can considerably weaken your position. Review the security, the instalment status and the deadlines first. In case of doubt it helps to arrange an initial consultation (72 euros) before you take further steps.

Completion, replacement contractor and open defects

Besides the money, the question of the building itself arises. Whether and how the project is continued depends on the decisions in the insolvency proceedings and on the ownership and security situation at the property. In some cases the project is continued, in others the buyers must organise the completion themselves.

If a replacement contractor is commissioned with the completion, their performance is to be clearly distinguished from the original contract. Record the construction status at takeover precisely, ideally with photos and an inventory, so that it remains recognisable later which performance stems from the insolvent developer and which from the new contractor.

If defects show on the performance already rendered, their classification and assertion is to be assessed separately. How to proceed after a handover and which rights exist is deepened in the article on the rights in case of construction defects after handover.

When legal help is sensible

The insolvency of a developer combines contract, security and insolvency law. Even the classification of your security and the question whether a claim is secured or unsecured requires a precise review of the contract, the instalment schedule and the security document. Mistakes regarding deadlines or the registration of claims can hardly be corrected later.

Early legal support helps to take the right steps in the right order, from contacting the trustee through the timely registration of the claim to the assertion of claims from a bank guarantee or insurance. The overview of the entire topic is offered by the topic page on the developer contract and the BTVG.

Even if a dispute over open payments or performances has already arisen, the early classification is worthwhile. How payment questions at the building can develop is shown in the article on the remuneration claim and refusal of payment.
