Formal Neutral

What it really means

A formal notice a landlord in England can use to end an assured shorthold tenancy without giving a reason, following strict legal rules and time limits. If you receive one, do not panic and do not move out immediately — check its validity with Shelter or Citizens Advice first.

Chinese explanation

英格兰房东用来终止 AST 租约的正式通知，无需说明理由，但必须遵守严格的法律程序和期限。收到后不要慌，也不要立刻搬走——先通过 Shelter 或 Citizens Advice 核实其有效性。

Example conversation

A: My landlord sent me a Section 21 notice. B: Get it checked by Shelter — quite a few of them turn out to be invalid.

A：房东给我发了 Section 21 通知。 B：先请 Shelter 帮你核查——不少这类通知其实是无效的。

What you could say back
