When the contract is the problem
Construction contract disputes often turn on the wording of the agreement.
The issue may be a missed notice, disputed variation, unclear scope, payment clause, extension of time request, defect allegation or termination step.
Before you act, you need to understand what the contract requires and whether the project records support your position.
This can help you decide whether to respond, negotiate, adjudicate, litigate or take another step.

Is this the right page for you?
This page is for you if the disagreement turns on what the contract says or what the parties agreed.
You may need help if:
- The contract terms are unclear
- The other side says you breached the contract
- You disagree about scope of work
- A variation was instructed but not paid
- A payment notice or pay less notice is disputed
- A deadline, programme or extension of time is contested
- Defects are being used to withhold payment
- You are considering termination
- You have received a termination notice
- The contract process was not followed
- You need to understand whether the contract supports adjudication or litigation
That separates this page from the general Construction Disputes page.

Contract wording can decide your next step
In a construction dispute, the contract often controls what you can claim, what you must do before acting, and what happens if the other side does not comply.
A missed notice, unclear scope, disputed variation or wrong termination step can change the position.
Before you respond or take action, you need to understand:
- What the contract requires
- What each party agreed to do
- Whether a notice was needed
- Whether the payment process was followed
- Whether the variation process was followed
- Whether defects affect payment
- Whether termination is available
- Whether the contract supports adjudication or litigation
The aim is to avoid acting on assumptions before the contract has been checked.
How My Commercial Lawyers reviews construction contract disputes
My Commercial Lawyers starts by reviewing the contract and the facts around the dispute.
The aim is to help you understand your legal and commercial position before you spend money on the wrong step.
1. Identify the contract issue
The first step is to work out what part of the contract is in dispute.
This may be payment, scope, variations, notices, delay, defects, completion, termination or breach.
2. Check the contract wording
The team reviews the clauses, schedules, amendments and any agreed terms that may affect the dispute.
This may include JCT, NEC or bespoke construction contract terms.
3. Match the contract to the evidence
The contract is then checked against what happened on the project.
This may include payment applications, notices, instructions, drawings, emails, site records, programmes or photographs.
4. Explain what the contract allows next
Once the contract position is clearer, the next step can be considered.
This may include a formal response, negotiation, adjudication, litigation or another route based on the contract and evidence.

Know the scope, fee and timeline before each instruction begins
My Commercial Lawyers works on a fixed fee instruction basis.
A construction contract dispute may involve more than one instruction. For example, one case may include several separate stages, such as reviewing the contract, advising on the position, preparing a formal response, starting adjudication or taking litigation steps where suitable.
Each instruction is scoped before it begins.
This means you know:
- What work will be carried out
- What the fee is for that instruction
- What the expected timeline is
- What is included
- What is not included
- What may need a separate instruction later
This helps keep the process clear and reduces the risk of confusion about fees, scope or timing.
The aim is clear advice, clear scope and practical next steps before you spend money on the wrong action.

My Commercial Lawyers helps you understand:
- What the contract says
- What obligations apply
- Whether notices were required
- What evidence supports your position
- Whether the other side has a valid argument
- Whether adjudication may be suitable

Construction contract dispute FAQs
What is a construction contract dispute?
A construction contract dispute is a disagreement about what a construction contract says, what the parties agreed, or whether one side has met its obligations.
It may involve payment, scope of work, variations, notices, delay, defects, termination or breach of contract.
What should we do if the contract is unclear?
Start by gathering the contract, amendments, key emails, payment records, notices and any project documents linked to the issue.
Do not rely on assumptions or send a formal response before the wording has been checked. The next step should be based on the contract, the project records and the evidence.
Can you help with JCT contract disputes?
Yes. My Commercial Lawyers can review suitable JCT contract disputes involving payment, notices, variations, delay, defects, termination and final accounts.
The team can help you understand what the JCT contract says and what the next step may be.
Can you help with NEC contract disputes?
Yes. My Commercial Lawyers can review suitable NEC contract disputes involving payment, compensation events, early warnings, notices, programmes, delays and contract administration.
The right next step will depend on the contract, the records and the commercial position.
Can you help with bespoke construction contracts?
Yes. If your construction contract is not a standard form, the wording needs careful review.
My Commercial Lawyers can review suitable bespoke construction contracts and help you understand the rights, obligations and risks before you respond or take action.
What if a variation was agreed but not paid?
A variation dispute usually depends on what was instructed, what was recorded, what the contract requires and what evidence supports the extra work.
Gather the contract, variation instruction, emails, site records, valuations, photographs and invoice details before asking for advice.
What if the other side says we missed a notice?
Notice requirements can affect payment, delay claims, extensions of time, variations and termination.
The contract should be reviewed to check what notice was required, when it had to be served, how it had to be sent and whether the project records support your position.
Can we terminate a construction contract?
Possibly, but termination can create risk if the contract does not support it or the correct process has not been followed.
Before terminating, you should review the contract terms, notice requirements, evidence of breach and the commercial impact of ending the contract.
Can adjudication help with a contract dispute?
Adjudication may help with some construction contract disputes, especially where payment, notices, variations or final accounts are involved.
It is not right for every matter. The contract, value, evidence and commercial position should be reviewed before deciding whether adjudication is suitable.
What should we send before you review the contract?
Send the signed contract, any amendments, key emails, payment applications, invoices, notices, drawings, specifications, variation records, delay records, site records and any formal correspondence.
If you are not sure what to send, start with the contract, the document that triggered the dispute and the key emails.
