Defence Statement — Invalid Section 21 Notice
A defence document for use in county court possession proceedings, arguing that a section 21 notice is invalid on one or more statutory grounds.
This template was not drafted by a solicitor.
It is an editorial reference based on the official sources we cite. You are responsible for any document you send. For high-stakes matters (court proceedings, large sums, deportation, criminal allegations, child welfare), have a regulated solicitor review or draft your document.
When to use this template
Use this template when your landlord has issued possession proceedings based on a section 21 notice and you believe the notice is invalid. Common grounds of invalidity include the notice being served too early, the landlord failing to protect your deposit, the landlord failing to provide required documents (gas safety certificate, EPC, How to Rent guide), or the property being subject to a selective licensing requirement that has not been met.
When NOT to use this template
Do not use this template if the possession proceedings are based on section 8 (rent arrears or other grounds) — those require a different defence. Do not use it if you have no valid ground of invalidity and simply want more time — courts take a dim view of unmeritorious defences. Seek specialist housing advice if your situation is complex.
Legal Basis
Housing Act 1988 s.21 (recovery of possession); Deregulation Act 2015 (conditions on service of s.21 notices); Assured Shorthold Tenancy Notices and Prescribed Requirements (England) Regulations 2015; Tenancy Deposit Schemes (Landlord's Duties) under Housing Act 2004 ss.212–215; How to Rent guide requirement under SI 2015/1646.
Before you send
- Failing to attend the possession hearing — a default possession order will be granted in your absence
- Raising only one invalidity ground when several may apply — check all statutory requirements have been met
- Not checking whether the deposit was protected within 30 days of receipt under the Housing Act 2004
Common Mistakes to Avoid
- ✗Failing to attend the possession hearing — a default possession order will be granted in your absence
- ✗Raising only one invalidity ground when several may apply — check all statutory requirements have been met
- ✗Not checking whether the deposit was protected within 30 days of receipt under the Housing Act 2004
- ✗Overlooking the prescribed information requirement — protecting the deposit alone is insufficient; the prescribed information must also have been given
- ✗Missing the 14-day deadline to file a defence after receiving the possession claim

IN THE COUNTY COURT AT [COURT NAME] Claim Number: [CLAIM NUMBER] **BETWEEN:** [LANDLORD'S NAME] — Claimant and [YOUR FULL NAME (TENANT)] — Defendant --- **DEFENCE** The Defendant, [YOUR FULL NAME (TENANT)], defends the Claimant's claim for possession of [PROPERTY ADDRESS] on the following grounds. **1. The Section 21 Notice is Invalid** The Claimant relies on a notice purportedly served under section 21 of the Housing Act 1988. The Defendant contends that the notice is invalid for one or more of the following reasons: **Ground 1 — [FIRST INVALIDITY GROUND (BRIEF HEADING)]** [DETAILS OF FIRST INVALIDITY GROUND] **Ground 2 — [SECOND INVALIDITY GROUND (BRIEF HEADING)]** [DETAILS OF SECOND INVALIDITY GROUND] **2. Deposit Protection** [YOUR POSITION ON DEPOSIT PROTECTION (REMOVE PARAGRAPH IF NOT APPLICABLE)] The Claimant failed to protect the Defendant's deposit of £[DEPOSIT AMOUNT (£)] in a government-authorised tenancy deposit scheme within 30 days of receipt, as required by sections 213–214 of the Housing Act 2004. Accordingly, pursuant to section 215 of the Housing Act 2004, the Claimant cannot serve a valid section 21 notice. **3. Prescribed Documents** [YOUR POSITION ON PRESCRIBED DOCUMENTS] Under the Assured Shorthold Tenancy Notices and Prescribed Requirements (England) Regulations 2015, a landlord cannot serve a valid section 21 notice unless, at the start of the tenancy, the tenant was provided with: (a) a copy of the current gas safety certificate; and (b) a copy of the property's EPC; and (c) the current version of the Government's How to Rent guide. The Claimant failed to provide [WHICH DOCUMENTS WERE NOT PROVIDED] before or at the commencement of the tenancy. **4. Conclusion** For the reasons set out above, the section 21 notice dated [DATE OF THE SECTION 21 NOTICE] is of no effect and the Claimant is not entitled to possession. The Defendant respectfully asks the Court to dismiss the claim. --- **STATEMENT OF TRUTH** I believe that the facts stated in this Defence are true. Signed: ___________________________ Name: [YOUR FULL NAME (TENANT)] Date: [DATE DEFENCE SIGNED] Address: [YOUR ADDRESS FOR SERVICE]

Frequently asked questions
- What are common reasons a section 21 notice might be invalid?
- A section 21 notice may be invalid if it was served too early, the landlord failed to protect your deposit, or required documents were not provided. These documents include the gas safety certificate, Energy Performance Certificate (EPC), and the How to Rent guide. Additionally, the notice is invalid if the property is subject to a selective licensing requirement that the landlord has not met.
- How does deposit protection affect the validity of a section 21 notice?
- Landlords must protect your deposit in a government-authorised scheme within 30 days of receipt. They must also provide prescribed information. If they fail to do this, they cannot serve a valid section 21 notice under sections 213 to 215 of the Housing Act 2004. You should check whether both protection and information were provided.
- Can I use this defence if my landlord is using section 8 grounds?
- No. This defence is specifically for section 21 notices. If your landlord has issued possession proceedings based on section 8, such as for rent arrears or other grounds, you require a different defence. Using this template for a section 8 claim would be incorrect and ineffective.
- Should I use this defence if I just need more time to pay rent?
- You should not use this template if you have no valid statutory ground of invalidity and simply want more time. Courts take a dim view of unmeritorious defences. If your situation is complex, you should seek specialist housing advice to determine if you have a valid legal argument.
