Estoppel definition

What does Estoppel mean? In practice, estoppel prevents a party from denying or reversing a state of affairs where, by words or conduct, it induced another to rely on it, and it would be unjust to allow that party to resile. It is primarily a case-law doctrine (equitable and common-law) rather than statutory, used across contract, property and civil procedure. Core elements commonly include: a clear representation or assurance; reasonable reliance; a change of position or detriment; and unconscionability. Main forms include: - Estoppel by representation of fact (common law). - Promissory estoppel (equity): typically suspends enforcement of existing rights and is generally a defence, not a...

Bars to decrees of nullity and estoppel in voidable marriages: England and Wales

Published by a LexisNexis Family expert

Practice notes

This Practice Note

This Practice Note sets out the situations in which the court may decline to issue a decree in nullity proceedings. It outlines the universal bar applicable to every matter, alongside the three bars confined to particular cases. It also addresses the issue of estoppel within nullity claims. From 6 April 2022, the Divorce, Dissolution and Separation Act 2020 (DDSA 2020) took effect.

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...
