A legal notice in England used by landlords to end an Assured Shorthold Tenancy (AST) and regain possession of their property, often called a "no-fault eviction."Derived from Section 21 of the Housing Act 1988, it allows landlords to seek possession without needing to prove a breach of tenancy by the tenant.It requires a minimum of two months' notice and compliance with strict legal requirements (e.g., deposit protection, EPC, Gas Safety Certificate). If the tenant doesn't leave, a court order is required for possession.
