What needs attention first?
This checklist suggests a review priority, not the likelihood of winning. Answers stay in this page and are not submitted.
What supports a claim for additional work?
Carrying out extra work and agreeing that it will be paid for separately are different questions. Identify who instructed the variation, what price or calculation method was agreed, and how completion was recorded. Contracts, estimates, messages, meeting minutes, site diaries and invoices should support the same sequence of events.
Will the site change before the evidence is recorded?
Replacement contractors, repairs or finishing work can obscure what was built and why a defect occurred. Preserve original drawings, specifications, photographs, inspection records and the work programme. Whether a pre-action evidence-preservation application or expert assessment is appropriate depends on what must be proved.
Can a successful claim be enforced?
Consider property, bank deposits and receivables that may have enforcement value, including prior-ranking rights. Provisional attachment preserves the prospect of enforcement; it does not itself recover payment. Direct payment of subcontract sums and possessory lien claims each have separate requirements and should not be assumed to apply.
Different records for different parties
Contractors should distinguish the original scope, variations, work completed and unpaid sums. Owners should separate uncompleted work, defects, delay, repair costs and any basis for deduction or set-off. A defect allegation does not automatically remove every payment obligation.

Does the absence of a written variation end the claim?
Not necessarily. Instructions, agreement, performance, acceptance and pricing records must be considered together.
Must a formal demand precede litigation?
It is not invariably a precondition. A demand can record the content and timing of a payment, termination or repair request.
Can all payment be withheld because of a defect?
The scope of defects, repair costs, unpaid price and any set-off or concurrent obligations require separate assessment.
