Can you do a lease extension without a solicitor?

You can't do a lease extension without a solicitor. You will have to use a solicitor or licensed conveyancer for at least part of the lease extension, whether formal or informal. We advise against trying to complete the other parts of the extension without a solicitor, as the risk of delaying your extension by a year outweighs the potential savings on solicitor's fees.

The Leasehold and Freehold Reform Act 2024 was passed on the 24th May 2024, but is not fully enforced yet and the date for this is not yet clear. We will update our content as and when the finalised legislation is published.

Certain legal aspects of a lease extension requires a solicitor. However, there are stages that you can complete yourself if you are confident to do so. The challenge with handling part of the process without the help of a solicitor is that without the professional expertise required for complex transactions such as this, you are likely to make a mistake, such as serving an incorrectly drafted Section 42 Notice. If your notice is incorrect, it will be rejected and you will have to wait 12 months before you can try again.

Do I need a solicitor for an informal lease extension?

Even if you choose to do an informal lease extension rather than using the formal process, a solicitor, or licensed conveyancer must handle the deed of variation and your payment.

What do I need to do to extend my lease?

While the answer to: Do you need a solicitor to extend your lease? is simply yes, there are certain parts of the process you could do yourself, although we don't recommend taking this risk.

Check if you qualify for formal lease extension

You can check if you meet the eligibility criteria for a formal extension yourself, if not you can ask the freeholder if they'd be willing to extend informally.

Instruct your solicitor

Choose a lease extension specialist with good reviews and compare quotes to get a good price.

Get a lease extension valuation

Getting an independent valuation is a good way to determine a fair price for the premium. You'll need a current market valuation from a RICS surveyor. If you don't use a RICS member, you may end up paying more that the property is worth and the landlord could dispute your valuation and make you pay for another one.

Negotiate your premium

This can be done yourself, but it will be easier with a solicitor which will often achieve a better result.

(If you can't agree on premium) Apply to Tribunal

If you are unable to compromise on a fair price for the extension, you can apply to tribunal to determine the premium.

Pay the premium

Your solicitor will handle the payment into your landlords account.
