JCT definition

What does JCT mean? JCT refers, in practice, to the Joint Contracts Tribunal and its suite of standard-form construction contracts used to procure building works and services. It is an industry shorthand rather than a term defined in legislation or case law. The JCT suite (including Design and Build, Standard Building Contract, Intermediate, Minor Works, term and framework contracts, sub-contracts and collateral warranties) provides a structured allocation of risk and clear provisions on design responsibility, payment and retention, variations, extensions of time, liquidated damages, loss and expense, insurance, termination and dispute resolution (including adjudication under the UK “Construction Act”).

Practice Note

This Practice Note reviews design obligations within the JCT suite of contracts—chiefly the Design and Build Contract (D&B) and the Standard Building Contract (SBC) where a Contractor’s Designed Portion applies (commonly termed a CDP). It also touches on the Intermediate and Minor Works forms. Across the JCT suite, the Contractor may assume design responsibility to different extents.

Tomlin orders in England and Wales: CPR guidance on drafting, confidentiality, approval, variation, enforcement, limitation, CCA issues, court-specific requirements, sample wording and precedents

This Practice Note This Practice Note reviews mechanisms used in settling litigation. A Tomlin order consists of a consent order paired with a schedule. It operates to stay proceedings on terms that have been agreed. The provisions contained in the schedule may remain confidential. This Practice Note describes the scope of confidentiality attaching to the schedule and sets out how it differs from a standard consent order. Sample wording for a Tomlin order is included, alongside links to precedents, as well as guidance on court approval. It also addresses varying, setting aside and enforcing a Tomlin order, including the considerations the court will take into account when handling applications for each. Further guidance is provided on interpreting and applying the relevant provisions of the CPR; however, some courts and divisions impose very specific requirements for both drafting and approval, and for approaching the schedule and confidentiality issues. Accordingly, you must consider the particular rules and court guide provisions in the forum where your claim is proceeding when drawing up the Tomlin order...
