A new subcontractor can take over a work package without resolving what the outgoing subcontractor is owed, who must repair defective work or whether the employer has released anyone. Treating site access as a complete legal handover can leave the main contractor paying twice or unable to trace responsibility later.
The right starting point is a three-part map: the existing contract, the legal route for the change, and the physical and financial position at the cut-off date. A handover should explain each part. It should not use "replacement" as if that word has one automatic legal effect.
This guide concerns contractual planning for a Kuwait project. Public procurement, a particular main contract and the facts of a dispute can add requirements. It does not authorize termination, a bond call or withholding payment in a particular case.
Decide whether this is subcontracting, assignment or a new contract
Under Civil Code Article 681, a contractor can entrust all or part of the work to a subcontractor unless the contract prohibits that or the nature of the work makes the contractor's identity material. Subcontracting does not change the original contractor's obligations to the employer; the contractor remains responsible to the employer for the subcontractor's work. [S1, Article 681]
Assignment is a separate issue. Article 680 addresses transfer of the contract with the other party's consent unless the contract provides otherwise, substitution in rights and obligations, and the requirements for effect against third parties. [S1, Article 680] Do not assume that permission to appoint a subcontractor is permission to transfer the whole contract or release the original contractor.
An outgoing subcontract may instead be brought to an end and a new subcontract made with another company. That route requires its own termination and payment analysis. The employer's consent to the incoming company's identity is not necessarily agreement to the outgoing company's final account or a release of the main contractor.
Write the chosen route in plain terms before circulating a handover agreement. Identify each party's capacity and the exact work package. If the parties intend a release or transfer, say whose rights change, from what date and subject to what conditions, then test whether the relevant law and contracts permit that result.
Check the right to stop the outgoing work before moving equipment
Collect the subcontract, amendments, instructions, notices and any default correspondence. Identify what contractual event is relied on, who may give notice, how notice must be served, and whether any cure process applies. A project manager's wish to change supplier is not itself proof of a contractual right to terminate without cost.
Civil Code Article 688 addresses the employer's ability to end the contract and stop work before completion, with compensation for expenses, completed work and profit the contractor could have earned, subject to the court's power to reduce the lost-profit component where fair in the circumstances. [S1, Article 688] Applying that provision within a subcontracting relationship requires review of the actual contract and facts. A convenience termination should not be relabelled a default termination to avoid dealing with the consequences.
If safety or an urgent site issue requires action, record it separately. Do not assume a later commercial settlement will cure every defect in the notice or evidence record.
Create a cut-off record both teams can understand
Use a dated inspection, with attendance and any disagreement recorded. Separate completed and accepted work, work awaiting inspection, incomplete work and alleged defects. Photographs should identify location, date and the item shown. Keep drawings, test results, instructions and versions, not just selected screenshots.
A useful handover schedule contains:
- Work areas and quantities, with the basis of measurement.
- Design, shop drawings and as-built records already supplied or still missing.
- Tests, approvals and inspections, including unresolved items.
- Materials on and off site, ownership documents and payment status.
- Plant, hired equipment, temporary works and access rights.
- Warranties, manuals, software, passwords and maintenance information, transferred through a secure process.
- Defects, disputed defects and the proposed party responsible for each next step.
An incoming contractor should not be required to acknowledge that all existing work is sound merely to obtain access. Equally, a reservation should be specific enough to help allocate work rather than becoming an unexplained statement that nothing is accepted.
Reconcile the final account without concealing disputes
Prepare separate columns for the outgoing subcontractor's claim, the main contractor's assessment, certified amounts, paid amounts and disputed adjustments. Identify retention, advances, variations, alleged delay amounts, defects costs and security. Explain the document behind each figure.
Do not treat a bond, a retention sum and a contractual claim as the same asset. Their wording and conditions differ. A proposed set-off or a bond call should be reviewed on its own basis, with attention to any notice or evidence requirements.
The incoming subcontract price should distinguish completion of unfinished work from rectification of existing work and genuinely new scope. Otherwise an apparent cost of "finishing the job" can include improvements that cannot fairly be passed to the outgoing party without further analysis.
If a partial payment is agreed, say whether it settles an identified amount only or the whole final account. Identify which claims and rights are reserved, who has authority to sign and what happens if payment is late.
Account for direct claims before agreeing the money flow
Civil Code Article 682 gives the subcontractor and workers engaged for the original contractor a direct claim against the employer for amounts owed to them, within the amount owed by the employer to the original contractor when proceedings are brought. It also addresses workers of the subcontractor. Article 683 provides a preferential right over relevant sums for the persons described in the preceding article. [S1, Articles 682-683]
Those provisions make the contract chain and timing important. They do not mean every lower-tier participant can claim every amount from every company on site. Trace the parties, contractual debts, sums remaining due and procedural position before deciding who should pay whom or accept a discharge.
A payment schedule should therefore identify the intended recipient, the debt being discharged and any supporting release or acknowledgment. It should not rely on an outgoing subcontractor's promise that no other claimant exists without checking the known record.
Define what the incoming subcontractor is taking on
The new agreement should identify the starting condition, scope, price basis, programme, testing and acceptance process. State which records can be relied on, what the incoming contractor must verify and how a newly discovered problem is notified and valued.
If it is intended to assume responsibility for some earlier work, define that responsibility and its limits. A general statement that the new contractor "takes over everything" may conceal a dispute about design, hidden defects, materials and warranties. Check insurance and third-party consents rather than assuming existing cover follows the work automatically.
Keep the main contractor's obligations to the employer in view. An allocation between the outgoing and incoming subcontractors does not by itself alter the employer's rights under the main contract or mandatory law.
Work through the handover as a practical scenario
Suppose a subcontractor leaves after installing part of a mechanical system. The replacement company quotes to finish installation and commission the system. The outgoing company claims unpaid variations; the main contractor alleges delay and defective installation.
Before signing, divide the replacement price into completion, rectification and new work. Preserve the current installation condition. Identify which design information and test records are missing. Set out how the parties will investigate a defect discovered during commissioning without assuming its cause in advance.
The final-account settlement and the new subcontract can then address different risks. Neither document should accidentally state that all previous defects have been released or that the incoming contractor has guaranteed work it has not inspected. This is an illustrative scenario, not a claim about a client matter or a court outcome.
What to prepare for legal review
Prepare the contract chain, amendments, notices, programme, measured progress, payment record, security instruments and proposed new scope. Identify urgent deadlines and any inspection or preservation step that cannot wait.
For wider context, use the firm's existing Kuwait construction-law guide. The construction and infrastructure practice can review the proposed route, notices, allocation and settlement documents within an agreed mandate. Start with the project role and proposed change; arrange a secure channel before sharing confidential contracts.
Questions project teams ask
Does employer approval of the new subcontractor release the main contractor?
Not by itself. Article 681 preserves the original contractor's obligations to the employer despite subcontracting. Any proposed release or transfer needs separate analysis and clear agreement.
Can the parties use one document for the whole change?
They can consider a coordinated agreement, but it still needs to separate termination or transfer, the final account, handover and the incoming scope. A short document is not a substitute for resolving those questions.
Can a subcontractor claim directly against the employer?
Article 682 provides a direct-claim mechanism subject to its conditions and limits. The particular contract chain, debts and timing must be reviewed; the provision is not a general promise of full payment.
Is a signed handover proof that every defect has been accepted?
Its effect depends on the wording, facts and applicable law. Record what was inspected, accepted, disputed or left open rather than relying on a broad label.
