Terminating a building contract for breach: organise grounds, evidence and settlement

1. Distinguish breach termination, notice and agreement

Termination for breach is not the same as giving notice because you no longer want the work. An agreed settlement has its own basis too. Classification can have major financial consequences. Do not send a general cancellation when responding to serious non-performance, and assess conduct such as withdrawing access in context.

ConsuWijzer distinguishes stopping for deficient execution from cancellation without that basis. After your message the contractor may argue you gave notice and demand another settlement. Before the final step, record facts supporting your declaration. A forceful tone does not strengthen an unclear basis.

For client termination by notice, article 7:764 BW gives a different settlement rule from breach termination. The starting point is the whole-work price less contractor savings from termination. It is not necessarily limited to hours already worked and materials ordered. For a price dependent on actual costs, the statute mentions costs incurred, work performed and profit the contractor would have made on the entire work.

Support the calculation: what work lapses, what costs remain avoidable and what obligations already exist? The rule does not prevent agreed price reduction, but distinguish mutual amendment from your own notice. Do not use cancellation, omitted work and breach termination interchangeably. A contractor’s price proposal is not automatically the correct statutory account either.

2. Describe the breach and its significance

Identify missing or defective agreed work and its project consequences. Attach contract, drawings, photographs and expert findings. Minor finishing points are not automatically equivalent to a fundamentally unusable structure. Assess termination’s extent against nature and significance of failure.

In ECLI:NL:RBAMS:2022:1657, Amsterdam district court discusses the statutory standard and exception for failure not justifying termination and its consequences. That does not guarantee your case is serious enough. Investigate contractor response and repair options too; a file showing only your complaints may be incomplete.

3. Check performance opportunity and default

Where performance remains possible, default is essential to the termination question. A written final period is a usual route. Sometimes default arises otherwise or impossibility matters. Assess your letters, periods and actual contractor statements rather than assuming a general exception.

The cited judgment also discusses the significance of responding to a specific repair-plan request. Not every unanswered email suffices. Gather full wording, sending evidence and context. Report later accepted planning too. Show access and cooperation with repair in the timeline.

4. Choose the extent of ending

Entire assignment or one defined unperformed part? Make the boundary concrete. Partial termination must leave remaining work and reciprocal performance clear. A new contractor needs to know what may be completed and what remains with the original party. Uncertainty complicates both execution and liability.

Ask what is legally and practically achievable. Literally reversing a largely built extension differs from undelivered materials. Do not demand refund treating the whole assignment as worthless without explanation. Useful-work value and defective performance each need support.

5. Work through payments and replacement costs

List contract price, changes and payments received. Then determine remaining performance after the chosen termination and required restitution or value compensation. The Amsterdam case illustrates that the precise claim matters. Having legal grounds does not mean every possible settlement has been correctly claimed.

Have replacement work priced separately as repair, completion and extension. This separates original-problem costs from new wishes. Assess damage, emergency measures and adviser costs separately. The difference between two total quotations is not automatically fully recoverable from the first contractor.

6. Organise declaration, site and proceedings

A final declaration should identify agreement, breach, earlier opportunities and extent. Preserve content and receipt evidence. Agree transfer of keys, material and file; record condition before third-party work. Acute danger may need temporary protection: document why waiting was irresponsible.

If disputed, establish the right court or dispute body from contract and valid terms. Urgent interim decision differs from final merits judgment. Collect formal papers with receipt dates and monitor deadlines. Do not wait for the insurer while a procedural deadline runs.

7. Fictional example: unfinished floor with useful preparation

Suppose a contractor largely prepares a storey but omits agreed installations. After several messages the client wants the whole contract ended and all advances returned. A third party can finish but also offers a costlier new layout.

Separate useful preparation, missing installations and new improvements. Assess partial termination and settlement to claim afterwards. This fictional example predicts no full refund. It shows why a termination letter and technical/financial inventory are both needed.

8. Checklist before final replacement

First ask the lawyer to confirm basis, period and declaration needed. Ensure the second contractor starts only within defined instructions. Keep evidence, execution and money claims in one schedule so practical resolution does not unnecessarily remove proof.

• Complete contract, terms and changes.
• Failures with photographs, agreements and expert support.
• Repair requests, deadlines, replies and accepted postponements.
• Payment account and useful/defective/missing work breakdown.
• Replacement quotation separating repair, completion and improvement.
