Turn that check into a working contract record. by [Jack Butler-Kettle]() ยท About 4 min readShare ## Before you start Obtain the complete agreed contract and the guidance or template you intend to use. Identify the particular task and any urgent deadline. JCT is a family of contracts, not one set of universal clauses. The 2024 edition does not automatically replace an existing 2016 agreement. A main contract and subcontract can also use different forms or editions. Check each agreement separately, including amendments and incorporated documents. Sources checked on 25 October 2026. ## Step-by-step guide 1. ### 1. Identify the actual agreement Record the form's full name, abbreviation, edition, parties and execution details. Obtain the conditions, particulars, schedules, amendments and incorporated documents. Do not use the date of signing as a substitute for the edition. A contract signed after 2024 can still use a 2016 form. Check document priority and any agreed amendments. If documents conflict, record the issue rather than selecting the clause that produces the preferred answer. Our [JCT explanation]() introduces the contract family. The [subcontract document checklist]() helps assemble the working pack. 2. ### 2. Check relevant edition differences The [JCT 2024 information booklet]() describes changes concerning electronic notices, time procedures, building-regulation responsibilities, termination accounting and other matters. These are review prompts, not substitute clauses. Confirm their presence and effect in your selected form, including amendments. Use the [JCT 2024 edition information]() to identify the published contract and supporting material. Then check the actual document before giving operational instructions. Scroll across to read all columns. Checks before carrying a process from one edition to another | Process | Check in the agreed contract | | --- | --- | | Serving a notice | Permitted method, address, recipient, notice type and evidence of service | | Time and money | Relevant event or matter, notification requirements and assessment procedure | | Design and statutory roles | Appointments, duties, design obligations and project-specific amendments | | Termination account | Grounds, notices, valuation and payment procedure before taking action | 3. ### 3. Map the applicable procedure For each recurring task, record the contractual source, trigger, responsible person, recipient, required information and deadline. Link the entry to the relevant document revision. Distinguish an extension of time from entitlement to additional money. Do not transfer a clause number or assessment period between forms without checking it. Similarly, electronic communication being available does not establish that every notice can be served by any email address. Check the selected options and applicable notice rules. Identify the relevant jurisdiction and mandatory law separately. A familiar contract label does not resolve every statutory question. The [payment and notices explanation]() and [delay comparison]() explain these separate commercial questions. 4. ### 4. Maintain checked working records Label working templates with the form, edition and project-specific basis. Keep a checked notice calendar and document register beside them. When using a Library article, check its stated form and edition. General explanations help identify questions; the executed agreement determines the contractual wording. Escalate uncertain service, termination or entitlement questions before taking irreversible action. Record the advice and the version relied upon. A [signed contract review]() can turn the actual agreement into a project action record. Update that record when the parties agree a change. **Before you finish:** Confirm every operational clause reference, recipient and deadline against the actual agreement. Record unresolved issues before relying on a generic template. ## Worked example ### The facts Fictional example: a subcontract signed in 2026 uses a JCT 2016 form with amendments. The team downloads a notice template labelled JCT 2024. ### What happens 1. The reviewer checks the signed documents and records the 2016 form, edition and amendments as the contractual starting point. 2. The team checks the intended notice against that agreement, including recipient, method, deadline and required information. It does not copy the 2024 clause reference. 3. The checked project template records its contractual source and review date. Any unresolved question is referred for advice before service. ### What this shows A newer template did not update the contract. The team uses a procedure supported by the agreement it actually made. ## Sources 1. [JCT 2024 Edition of Contracts: information booklet](). The Joint Contracts Tribunal. 2.
