Why choose My Commercial Lawyers for a JCT contract dispute?

A JCT dispute can turn on more than one clause.

The contract may have been amended. Payment notices may be disputed. One side may rely on delay, defects or termination terms that the other side interprets differently.

My Commercial Lawyers focus on construction disputes. The firm provides barrister-led construction dispute support, with litigation conduct where suitable.

Relevant experience includes:

  • JCT and FIDIC-aligned construction contracts
  • Employer and subcontractor contract disputes
  • JCT contract termination for non-payment
  • Unpaid fees for architects and construction professionals

The aim is to help you understand where you stand before you spend money on the wrong action.

What kind of JCT contract dispute are you dealing with?

You may already know the problem. What you do not know is what the contract allows you to do next.

My Commercial Lawyers may review suitable disputes involving:

Payment disputes under JCT contracts

You may have completed the work but not been paid.

The dispute may involve a payment application, valuation, deduction, pay less notice, final account or disagreement over what is due.

Before choosing a recovery route, the contract, notices and evidence need to be reviewed.

JCT variation disputes

Changes to the scope of work can lead to disagreements over instruction, valuation and payment.

The dispute may be about whether a change was properly instructed, what it is worth or who should carry the cost.

Delay and extension of time disputes

A project may be late, but the parties may disagree about why.

The dispute could involve extensions of time, responsibility for delay, project records, notices or financial consequences.

Defect disputes

One side may allege that work is defective or does not meet the contract requirements.

The other side may dispute responsibility, the extent of the defect or whether payment can be withheld.

JCT termination disputes

Termination can have serious commercial consequences.

Before taking or responding to a termination step, the contract, notices and circumstances need careful review.

Contractor and subcontractor disputes

The dispute may sit between an employer and main contractor, or between a contractor and subcontractor.

The right next step depends on the agreement between the parties and what has happened on the project.

Do not assume the standard JCT wording tells you where you stand

There is more than one type of JCT contract.

Your position can depend on the contract used, the edition, the completed contract details and any amendments.

You may also need to check:

A standard JCT form may also have been amended before it was signed.

Those changes can affect risk and responsibility. The starting point should be your actual contract, not a general explanation found online.

How My Commercial Lawyers reviews a JCT contract dispute

The first question is not whether you should start adjudication or go to court.

The first question is where you stand.

1. Clarify the issue

The team reviews the facts, contract and evidence.

This may include the signed JCT contract, amendments, notices, applications, invoices, emails and project records.

2. Review the options

Possible routes may include:

  • Negotiation
  • A formal response
  • Adjudication
  • Litigation
  • A payment recovery route
  • Another step

The right route depends on the dispute, contract, evidence and commercial reason to proceed.

3. Make the next step clear

You need to understand what the dispute involves and what the next step could be.

The aim is to give you clearer direction before you spend money on an action that may not fit your position.

Is adjudication the right next step for your JCT dispute?

It may be.

Adjudication is a common route for construction disputes, but it should not be treated as the answer to every JCT problem.

Before deciding, consider:

The question is not only, “Can we adjudicate?”

You also need to ask whether adjudication is the right next step for this dispute.

A JCT dispute may start with payment and become something wider

“We’ve done the work, but we haven’t been paid.”

That may be how the problem starts.

The other side may then raise alleged delays, defects, variations or failures to follow the contract.

You may suddenly be dealing with several issues at once.

This is where the contract and evidence matter. Sending another chasing email may not answer the wider dispute.

You need to know where you stand.
