MOU meaning

Published by a LexisNexis Energy expert
What does MOU mean?
A memorandum of understanding (MOU) records the parties’ intentions and principal terms of a proposed transaction or collaboration to guide negotiations and approvals. It is not defined in legislation; the term is used across corporate, commercial, real estate and public‑sector practice. Whether an MOU is binding depends on intention to create legal relations, contractual certainty and consideration. Many MOUs are expressly non‑binding and marked “subject to contract”, but specific provisions—such as confidentiality, exclusivity/lock‑out, intellectual property, costs, governing law and jurisdiction, and dispute resolution—are often drafted to be legally enforceable. UK case law (including RTS Flexible Systems v Müller) confirms that labels are not conclusive: sufficiently certain terms and conduct can create a binding contract even if the parties anticipate a later formal agreement. Pure “agreements to agree” or to negotiate in good faith are generally unenforceable. Usage and legal analysis are broadly consistent across England & Wales, Scotland, Northern Ireland and Ireland. Scots practice also refers to heads of terms and letters of intent; land contracts proceed by concluded missives. In England & Wales, Northern Ireland and Ireland, the “subject to contract” formula—especially in property—strongly indicates no binding contract until formal documents are executed.

The criminal cartel offence in the UK: pre-2014 dishonesty test, ERRA 2013 reforms, statutory exclusions and defences, CMA/SFO MoU, prosecution guidance and immunity

The creation of the Competition and Market Authority (CMA) in 2013 The establishment of the Competition and Market Authority (CMA) in 2013 coincided with an overhaul of a component of the criminal cartel offence that prosecutors had to prove to convict directors and officers. When the Enterprise and Regulatory Reform Act 2013 (ERRA 2013) commenced on 1 April 2014, the dishonesty element of the cartel offence was scrapped, marking a radical change to what prosecutors had previously been required to establish. Under the revised regime, an individual commits the offence by agreeing, with one or more persons, that two or more undertakings will take part in specified prohibited cartel arrangements (price-fixing, market-sharing, bid-rigging, or limiting output), regardless of dishonesty. Any such arrangements must have occurred in the UK to be caught. As explained further below, this shift is partly offset by new exceptions, covering notification of customers, publication of arrangements, and compliance with a legal requirement, as well as defences, including that the accused did not intend to conceal...
