Change meaning

What does Change mean?
In legal practice, a Change is an agreed alteration to the scope, specification, deliverables, timetable or method of performance of works or services under a contract, together with any resulting adjustment to price, time and risk. It is a descriptive term rather than a statutory definition, though standard forms and sector practice give it structure. In construction, the concept is usually termed a “variation” (eg JCT, FIDIC) or dealt with through compensation events/changes to Scope (NEC). In outsourcing, IT and facilities management, Changes are administered through a change control procedure; in PFI/PPP, a change protocol sets detailed rules for Authority, Contractor and Mandatory Changes. In public procurement, post‑award Changes are regulated as “modifications” and are only permitted within the limits set by the relevant procurement regulations in England and Wales, Scotland, Northern Ireland and Ireland. Typical features include a formal Change Request and Change Order/Instruction; defined approval thresholds; evaluation of impact on programme, milestones, service levels/KPIs and payment mechanisms; methods for pricing (rates, lump sum, benchmarking) and for granting extensions of time or relief. Some contracts allow unilateral instructions (commonly by the employer), but most service Changes require bilateral agreement.

Property transactions: planning due diligence on use—permissions, conditions, enforcement, immunity and reporting (England and Wales)

Section 57 of the Town and Country Planning Act 1990 (TCPA 1990) requires planning consent for any material change in the use of buildings or land. Any limitations or conditions attached to a permission must likewise be adhered to. Liability for any existing breach will transfer to the purchaser. It is therefore essential to verify that the current use of the entire property is properly authorised and that all related conditions are being complied with, or to establish whether any unauthorised use or breach has become immune from enforcement. For further information, see Practice Note: Material change of use. Is the use authorised? Confirm the permitted use of the property, or, where relevant, each planning unit, and determine whether that use is authorised by: an explicit planning permission a certificate of lawful use, or permitted development rights If the permitted use does not mirror an express planning permission, do not assume it is unlawful; it may still be authorised by...

Herfindahl–Hirschman Index (HHI) in merger control: calculation, examples, thresholds, delta interpretation and red flags—practical checklist for competition lawyers

To gauge concentration within a particular market, competition authorities often turn to the Herfindahl‑Hirschman Index (HHI) as a primary tool that supports and streamlines their assessment. Although the absolute HHI level provides an early signal of post‑merger competitive pressure, the movement in the HHI (the ‘delta’) functions as a practical proxy for the change in concentration directly attributable to the merger itself and its immediate effects. How to calculate the HHI The HHI is obtained by adding the squares of the individual market shares of all firms participating in the market, without omitting any active competitor...

Deed poll at 16: can mother execute without father’s PR consent?

When a baby is born, the birth must be registered, and the surname entered at that time is intended to be the name by which the child is known. If a parent later wishes to change the child’s surname, they should first consult any other person who holds parental responsibility before any step is taken. This applies irrespective of the existence of a child arrangements order, and regardless of whether that person has contact with the child (Re PC (Change of Surname)). Where there is disagreement, the matter must be placed before the court for a determination. A contested change of surname must not be made unilaterally (Dawson v Wearmouth). Altering a name is a significant matter and should not be approached lightly. In deciding whether to grant leave, the court is guided by the welfare principle in section 1(1) of the Children Act 1989 (ChA 1989), and will act accordingly...

LTA 1954 contracting-out: AFL plan changes, no boundary change

Form LTBT1 Form LTBT1 is prescribed by the Regulatory Reform (Business Tenancies) (England and Wales) Order 2003, SI 2003/3096 (the Order). Where the parties intend to contract out of, or exclude, sections 24–28 of the Landlord and Tenant Act 1954 (LTA 1954), the Order stipulates that particular steps must be completed before any such agreement is concluded. Landlords frequently seek the flexibility of a contracted‑out lease, as it allows the tenancy to end on expiry of the term without the tenant acquiring a right to a new lease. Under the LTA 1954, the former position required court approval for a contracted‑out arrangement (the Pre‑2004 Procedure). The Order replaced that regime with a new process that obliges the landlord to serve a warning notice in, or in a form substantially similar to, that set out in SI 2003/3096. This notice must be given before the lease is granted or, if the parties propose to enter into an agreement for lease, before that agreement is made, because the tenant must receive...
