Terminating a Construction Contract: Free Termination, Good Cause and Withdrawal
A construction contract can be ended – but the BGB knows several routes with very different cost consequences. This guide explains free termination under Section 648, termination for good cause under Section 648a and withdrawal from a consumer building contract under Section 650l in outline, classifies the cost consequences and refers to specialist legal advice.
Sometimes a construction contract should or must be ended – because of delay, defects, a growing loss of trust, or because a withdrawal (Widerruf) is possible. For this, the German Civil Code (BGB) provides several routes with very different cost consequences. This guide explains the free termination under § 648, the termination for good cause under § 648a and the withdrawal of the consumer construction contract (Verbraucherbauvertrag) under § 650l in outline.
Important note
This article provides general orientation and does not replace legal advice. Terminating and withdrawing from a construction contract have significant financial consequences – seek advice in advance from a specialist lawyer for construction and architecture law.
Short answer: The BGB allows three routes: the free termination under § 648 (possible at any time, but the contractor keeps the claim to remuneration minus saved expenses), the termination for good cause under § 648a (only work actually performed is to be paid) and the withdrawal of the consumer construction contract under § 650l within 14 days. Which route fits depends on the type of contract and the reason for termination.
What does the free termination under § 648 BGB mean?
Short answer: Under § 648 BGB, the client can terminate the construction contract at any time and without giving a reason. The catch: the contractor retains the claim to the agreed remuneration, but must offset saved expenses and earnings from other work. In practice, you therefore pay part of the profit for work not performed – the free termination is thus usually the most expensive option.
The free termination is therefore less a financial than an organisational last resort: it ends the collaboration, but costs a large share of what you would have paid anyway. It makes sense above all if you want out of the contract without a provable breach of duty, for example because your life plans have changed. Important: the contractor must offset what they save on materials and wages through non-performance, as well as what they earn elsewhere in the time freed up. Anyone who keeps a clean record of this offset can often significantly reduce the remaining claim.
Before you terminate, you should check the contract carefully. How to do this and what traps to look out for is shown in the guide Checking the construction contract.
When is a termination for good cause possible?
Short answer: The termination for good cause under § 648a BGB comes into consideration when continuation is unreasonable – for example in the case of significant delay, serious defects or payment breaches. As a rule, the precondition is setting a deadline together with a threat of termination. The big advantage: you pay only for the work actually performed, not for lost profit.
Termination and withdrawal routes in the construction contract (in outline)
| Route | Provision | Cost consequence |
|---|---|---|
| Free termination | § 648 BGB | remuneration minus saved expenses |
| Good cause | § 648a BGB | only work performed to be paid |
| Withdrawal | § 650l BGB | reversal of the contract, compensation for value possible |
The good cause must objectively exist and can be disputed by the construction company in the event of a dispute. Documentation is therefore crucial: written complaints about defects, deadlines with a clear threat of termination, photos and – where possible – the assessment of an independent building surveyor. Anyone who hastily terminates on the grounds of supposedly good cause, even though the preconditions are not cleanly substantiated, risks the termination being reinterpreted as an expensive free termination under § 648. This reinterpretation is one of the most common and most expensive mistakes when ending a contract.
In the case of delay, it is worth looking at your rights: the guide Construction delay: your rights explains when delay exists and which claims arise.

How does the withdrawal of the consumer construction contract work?
Short answer: With a consumer construction contract, you are entitled to a 14-day right of withdrawal under § 650l BGB. The period only begins with a correct withdrawal notice (Widerrufsbelehrung) – if this is missing or faulty, the period is significantly extended. The withdrawal leads to a reversal of the contract; for work already performed, compensation for value (Wertersatz) may be due.
Withdrawal differs fundamentally from termination: it reverses the contract retroactively rather than ending it for the future. The precondition is that a consumer construction contract actually exists – that is, a contract with a consumer for the construction of a new building or substantial conversion works. The 14-day period is tight, but is considerably extended by a missing or faulty withdrawal notice. Therefore check the notice carefully before assuming that a withdrawal is no longer possible – on this point in particular, specialist legal advice is worthwhile.
What makes a consumer construction contract and which mandatory details it must contain is explained in detail in the guide Checking the construction contract.
What cost consequences does a termination have?
Short answer: The cost consequence depends on the route: with the free termination you owe the remuneration minus saved expenses, with the termination for good cause only the work performed. A withdrawal leads to a reversal with possible compensation for value. A joint measurement/performance assessment (Aufmaß) protects against disputes over the share already performed.
- Check the contract and grounds for termination – ideally with a lawyer.
- For good cause: set a deadline with a threat of termination and document it.
- Always declare the termination or withdrawal in writing and in a provable way.
- Jointly assess the work performed (measurement, photos, protocol).
- For a consumer construction contract, check the withdrawal notice and the start of the period carefully.
Conclusion: check first, then terminate
Whether free termination, good cause or withdrawal – the right choice determines the costs. Check the contract carefully, document everything in writing and seek legal advice before terminating. You will find official legal texts at Gesetze im Internet; neutral consumer information is provided by the Verbraucherzentrale (consumer advice centre).
