Serving a Section 42 Notice for a Lease Extension
A Section 42 Notice (also known as a Tenant's Notice) is the formal legal document used by a qualifying leaseholder to claim their statutory right to a lease extension under the Leasehold Reform, Housing and Urban Development Act 1993.
Serving this notice officially starts the legal process with your freeholder, fixes the valuation date, and sets a strict statutory timeline. Because any technical errors can render the notice invalid and bar you from reapplying for 12 months, it must be drafted and served with absolute precision.
In this article we'll explain how to serve a section 42 notice, what to do if there is a superior landlord, the common mistakes, costs and timescales.

- Immediate eligibility: The requirement to have owned your property for two years before serving a notice was abolished by the Leasehold and Freehold Reform Act 2024. You can now serve a Section 42 Notice from day one of ownership.
- The 90-year extension: Serving the notice triggers your legal right to extend the lease by 90 years and reduce the ground rent to a peppercorn (zero).
- Strict timelines: The notice must give the freeholder at least two months to respond with a formal Counter-Notice.
- The 12-month penalty: If your notice is deemed invalid or you miss a statutory deadline, your claim is withdrawn and you are legally barred from applying again for 12 months.
What is the purpose of a Section 42 Notice?
A Section 42 Notice formally notifies the freeholder of your intention to extend your lease and establishes your opening offer for the premium. The freeholder must respond by the deadline specified in your notice, which must be no less than two months from the date of service.
Common scenarios for serving a notice
- A homeowner extending their lease: This is the most common scenario. Following the abolition of the two-year ownership rule, a leaseholder can now serve a Section 42 Notice to extend their lease from the first day of their legal ownership.
- A seller assigning the rights: Because buyers no longer have to wait two years to apply themselves, assigning the notice is less common today. However, a seller can still serve a notice on the freeholder and assign the benefit of that notice to the buyer upon completion, allowing the buyer to take over the existing claim immediately.
Expert Tip: You must wait for HM Land Registry completion
With the abolition of the two-year rule, you might assume you can serve a Section 42 Notice on the exact day you get your keys. However, if you serve the notice before HM Land Registry has officially updated the title register with you as the new proprietor, your notice is legally invalid .
To serve a valid Section 42 Notice, you must hold the legal title, not just equitable title. Registration can take upwards of six months after completion. If you need to extend your lease urgently after buying, your solicitor must apply to HM Land Registry to have your registration expedited. Once approved, an expedite request usually requires the registration to be completed within 10 working days, allowing you to serve the notice safely.

What must a Section 42 Notice contain?
The Section 42 Notice is a prescribed form that must contain specific statutory information. To be considered valid, it must include:
- The full name of the leaseholder and the address of the property.
- Sufficient particulars of the property and the original lease details, including the commencement date and term granted.
- The premium you propose to pay for the lease extension.
- The terms you propose should be contained in the new lease.
- The name and address of your appointed representative (usually your conveyancing solicitor).
- A specified date by which the landlord must respond with a Section 45 Counter-Notice, which must be at least two months after the date the Section 42 Notice is given.
Can you serve a Section 42 Notice yourself?
While the law permits leaseholders to draft and serve their own notice, most instruct a specialist lease extension solicitor. If your freeholder finds faults or inaccuracies in your notice, they have the right to apply to the court to have it dismissed.
The 12-Month Invalidity Penalty
If your application is dismissed due to errors in the notice, your current claim is stopped. Crucially, you are then legally barred from making another statutory claim for 12 months.
During this waiting period, your lease will continue to shorten, which will inevitably increase the premium you must pay the next time you apply. You will also have wasted time and be liable for the freeholder's reasonable legal fees incurred as a result of the failed attempt.
Case Studies: Getting a Section 42 Notice wrong
You may think serving a section 42 notice is easy, and try and do it yourself; however, here are some case studies demonstrating different ways a notice can fail:
- The "Realistic Premium" Rule: Cadogan Estates Ltd v Morris [1998]. In this case, the leaseholder proposed an unrealistically low premium of £100. The court invalidated the notice because it was not recognisable as a genuine proposal. This established that opening offers must have a realistic basis, and nominal figures will cause the claim to be struck out.
- Missing Required Particulars: Speedwell Estates Ltd v Dalziel [2001]. The leaseholder served a notice that lacked the required particulars, including tenancy instruments and occupation details. The Court of Appeal confirmed that the notice was entirely invalid. As a result, the leaseholder was forced to restart the process, pay the landlord's costs, and wait at least 12 months before serving a fresh notice.
- Incorrect Response Deadlines: Free Grammar School of John Lyon v Secchi [1999]. A Section 42 Notice must give the landlord at least two months to respond with a Counter-Notice. In this case, the leaseholder specified a date that was too early. The court rejected the argument that a "reasonable recipient" would understand the mistake, ruling that the strict statutory timeline was breached and the notice was invalid.
- Serving the Wrong Landlord: Lay v Ackerman [2004]. The notice was served on an incorrect landlord rather than the true "competent landlord". The court invalidated the notice entirely due to improper service.
How does the landlord respond? (The Counter-Notice)
Once you serve a valid Section 42 Notice, your freeholder is legally obliged to respond by serving a Section 45 Counter-Notice within the timeframe specified in your notice (which must be at least two months).
If the freeholder fails to serve a valid Counter-Notice within this period, they may be legally obliged to grant the lease extension on the exact terms and premium you proposed in your original Section 42 Notice.
If the freeholder admits your right to extend, their Counter-Notice will either:
- Accept your proposed terms and premium.
- Accept your right to extend but propose a different premium (a counteroffer).
Once a counteroffer is served, your respective RICS surveyors have a statutory six-month period to negotiate the premium. If no agreement is reached, either party may apply to the First-tier Tribunal (Property Chamber) to determine the final cost.
The statutory lease extension process
Before your solicitor serves the notice, you must complete the following preparatory steps:
Check your eligibility
You must hold a qualifying long lease (originally granted for more than 21 years). Thanks to the Leasehold and Freehold Reform Act 2024, the previous requirement to have owned the property for two years has been abolished.
Get a RICS premium valuation
You must instruct a RICS-qualified surveyor to provide a professional valuation. This report assesses the market value of the premium based on the statutory formula and provides the "best-case" opening offer that your solicitor will insert into your Section 42 Notice.
Instruct your solicitor
Your solicitor will identify the competent landlord, draft the notice accurately, and serve it via the correct legal channels. They will also register the notice at HM Land Registry to protect your claim against the title.
Dealing with an Absent Freeholder
If your landlord or freeholder cannot be located or is unresponsive, you cannot follow the standard Section 42 process. Instead, your solicitor must apply to the County Court for a Vesting Order to force the extension through in their absence.
