CONSTRUCTION PROJECT PAYMENTS | WHEN IS WITHHOLDING PAYMENT JUSTIFIED & HOW SHOULD FINANCIAL DISPUTES BE HANDLED?
Introduction
Construction project payments are a critical part of successful project execution. Contractors, subcontractors, suppliers and clients all depend on agreed payment arrangements to keep materials, labour, fabrication and site activities moving.
However, payment disputes can arise when a client believes work is incomplete, defective, delayed or different from the approved scope. In other situations, a contractor may believe that completed work has been properly delivered but payment has been delayed or withheld without sufficient explanation.
The important question is therefore not simply whether payment has been withheld. It is why the payment has been withheld, what the contract says, and whether the reason is supported by the project records.
For interior design, renovation and fit-out projects, having a clear quotation, payment schedule, scope of work and variation procedure can significantly reduce financial disagreements.
What Does Withholding a Construction Payment Mean?
Withholding payment generally means delaying or retaining all or part of an amount that would otherwise be payable under a construction contract.
Depending on the contract, withholding may relate to issues such as:
- Incomplete work
- Defective workmanship
- Unapproved variations
- Outstanding documentation
- Failure to meet contractual requirements
- Disputed quantities or measurements
- Failure to achieve an agreed project milestone
The specific rights of each party depend on the contract terms and applicable law. A party should therefore avoid assuming that any construction payment can simply be withheld whenever there is dissatisfaction with the project.
When May Withholding Payment Be Justified?
1. When the Contract Expressly Allows It
The first consideration should always be the signed agreement, quotation or contract.
Payment terms may specify circumstances in which an amount can be retained, deducted or withheld.
Before withholding payment, the party should identify:
- The relevant contract clause
- The payment milestone involved
- The amount affected
- The reason for withholding
- Any notice required
- The procedure for resolving the issue
The contract should guide the process rather than an informal decision made during project execution.
2. When There Is a Genuine and Documented Performance Issue
Payment may be disputed where there is a genuine contractual issue involving the quality, quantity or completion of the agreed work.
For example, if a contractor has not completed an agreed installation milestone, the client may have grounds to question payment associated with that milestone, depending on the contract.
However, the issue should be documented clearly.
Useful records may include:
- Approved quotation
- Signed contract
- Site reports
- Progress records
- Photographs
- Inspection reports
- Approved drawings
- Payment certificates
- Invoices
- Correspondence
Documentation helps distinguish a legitimate payment dispute from a general disagreement.
When Should Payment Generally Not Be Withheld?
Payment should not automatically be withheld simply because a party is unhappy with an unrelated aspect of the project.
For example, a client should not necessarily withhold an entire payment because of a minor issue affecting only a small portion of the agreed work.
Similarly, a contractor should not automatically withhold a subcontractor’s payment simply because the contractor is experiencing unrelated cash-flow difficulties.
The contractual entitlement should be assessed carefully.
In Kenya, public procurement regulations expressly require a procuring entity to make prompt and timely payments to a contractor that has satisfactorily performed its contractual obligations, subject to the applicable contract requirements. (Kenya Law)
What About Defective or Incomplete Work?
Defective or incomplete work can create a legitimate payment dispute, but the response should be proportionate and based on the contract.
A practical process is:
Identify the issue → Document the issue → Notify the responsible party → Agree corrective action → Confirm completion → Process the applicable payment.
This approach gives the contractor or subcontractor an opportunity to correct the problem while protecting the client’s contractual interests.
The objective should be resolution rather than unnecessary financial escalation.
What Happens When a Client Disputes an Invoice?
A disputed invoice should be reviewed against the agreed quotation, contract and project progress.
The parties should establish:
- What amount was invoiced?
- What project milestone does it relate to?
- What work has been completed?
- What payment has already been made?
- What amount remains outstanding?
- What specific amount is disputed?
- Why is it disputed?
- What does the contract say about the dispute?
Separating the disputed amount from the undisputed amount can help prevent an entire project payment from becoming unnecessarily blocked.
How Should Contractors Handle Delayed Payments?
Contractors should maintain proper payment records throughout project execution.
A payment tracker can include:
| Payment Item | Amount | Due Date | Status | Reason for Delay |
|---|---|---|---|---|
| Initial deposit | Agreed amount | Contract date | Paid/Pending | — |
| Progress payment | Agreed amount | Milestone | Paid/Pending | — |
| Variation | Approved amount | Agreed date | Paid/Pending | — |
| Final payment | Balance | Completion | Paid/Pending | — |
When payment is delayed, the contractor should first communicate with the client and establish whether the issue concerns documentation, project progress, quality, valuation or another contractual matter.
How Should Financial Disputes Be Handled?
The best approach is to follow the dispute-resolution procedure agreed in the contract.
A sensible escalation process is:
Step 1: Review the Contract
Identify the payment terms, obligations, notices and dispute-resolution procedure.
Step 2: Review the Project Records
Compare the payment claim against quotations, invoices, drawings, approvals, site records and completed work.
Step 3: Communicate in Writing
The parties should clearly state:
- The amount claimed
- The amount disputed
- The reason for the dispute
- The contractual basis
- The proposed resolution
Step 4: Attempt Negotiation
Many payment disagreements can be resolved through direct discussion before formal proceedings become necessary.
Step 5: Use the Contractual Dispute-Resolution Mechanism
Depending on the agreement, this may involve negotiation, mediation, adjudication or arbitration.
Kenyan construction disputes have traditionally used mechanisms such as arbitration, while recent developments have also focused attention on adjudication as a potentially faster mechanism for construction payment disputes. (oraro.co.ke)
Why Written Records Matter in Construction Payment Disputes
A construction payment dispute can become difficult when the parties rely primarily on verbal conversations.
Written records provide evidence of what was agreed and what happened during execution.
Important documents include:
- Signed quotations
- Contracts
- Payment schedules
- Invoices
- Receipts
- Variation approvals
- Material approvals
- Site reports
- Completion records
- Emails and written correspondence
For example, a recent Kenyan High Court construction dispute examined contractual payment arrangements between a contractor and subcontractor, including the effect of a pay-when-paid provision and whether it changed the underlying payment obligation. (Kenya Law)
This illustrates why payment clauses should be understood before a project begins rather than only after a dispute develops.
How Can Construction Payment Disputes Be Prevented?
The best payment dispute is one that is prevented through proper project planning.
Before project execution begins, the parties should clearly establish:
✔ Total project price
✔ Payment schedule
✔ Initial deposit
✔ Payment milestones
✔ Scope of work
✔ Material specifications
✔ Completion requirements
✔ Variation procedure
✔ Payment due dates
✔ Defects and correction procedures
✔ Dispute-resolution process
Clear documentation gives both parties a common reference point throughout the project.
Why Payment Planning Matters for Interior Projects
Interior projects can involve multiple financial commitments at different stages.
A typical project may require funds for:
Design → Procurement → Fabrication → Delivery → Installation → Finishing → Completion
For example, kitchen cabinets or wardrobes may require material procurement and fabrication before installation takes place.
This means the agreed payment schedule should be structured around the actual execution requirements of the project.
A well-planned payment arrangement helps the contractor coordinate suppliers, fabricators, labour and installation without unnecessarily disrupting project progress.
Frequently Asked Questions
When can a construction payment be withheld?
A construction payment may be withheld where the contract permits withholding and there is a valid contractual reason, such as a documented performance issue, incomplete work or another specified entitlement. The exact position depends on the contract and applicable law.
Can a client withhold the entire construction payment because of a small defect?
Not necessarily. The appropriate response depends on the contract, the nature of the defect and the amount genuinely in dispute. The parties should review the contractual payment and dispute provisions.
What should a contractor do when a client delays payment?
The contractor should review the payment terms, confirm the amount due, document completed work, communicate with the client in writing and follow the agreed dispute-resolution procedure if the issue remains unresolved.
How can construction payment disputes be prevented?
Clear contracts, payment schedules, scope definitions, variation procedures, progress documentation and written communication can significantly reduce payment disputes.
Should construction payment disputes go directly to court?
Not necessarily. The contract may require negotiation, mediation, adjudication or arbitration before or instead of litigation. The appropriate process depends on the contract and applicable law.
Why is a payment schedule important?
A payment schedule establishes when project payments become due and allows both the client and contractor to plan project execution, procurement, labour and other financial commitments.
Conclusion
Construction project payments should be managed according to the agreed contract, documented project progress and clearly defined payment procedures.
Withholding payment may be justified in certain circumstances, particularly where the contract permits it and there is a genuine, documented issue affecting the payment entitlement. However, withholding payment without understanding the contractual position can escalate an otherwise manageable disagreement.
The most effective approach is to establish clear payment terms before project execution, maintain accurate project records, communicate concerns promptly and use the agreed dispute-resolution process when disagreements arise.
For contractors and clients alike, transparent payment schedules, proper documentation and professional project management are essential for keeping construction and interior projects financially and operationally on track.
