Checklist for Registering a Lease Extension: Avoiding HM Land Registry Requisitions

When dealing with a short lease (typically any residential lease with under 85 years remaining), extending the lease term is vital to protect the property’s market value and ensure mortgageability.

However, after negotiating the premium and executing the deed, the transaction can still hit hurdles at HM Land Registry (HMLR). Requisitions delay registration, increase administrative costs, and create legal uncertainty for buyers and lenders.

Use this checklist to ensure your lease extension application is registered correctly on the first attempt.

1. Pre-Submission Verification & Short Lease Checks

Before submitting your application to HM Land Registry, confirm the underlying lease details:

• Verify the Remaining Unexpired Term: Ensure the existing lease qualifies as a short lease requiring statutory extension under the Leasehold Reform, Housing and Urban Development Act 1993 (or an agreed voluntary route).

• Confirm Title Number(s): Check both the leasehold title number and the landlord’s freehold or intermediate leasehold title numbers.

• Review Lender Consent Requirements: If there is a mortgage secured against the short lease, confirm whether a formal deed of substituted security or lender consent is required prior to registration.

2. Document Preparation Checklist

A complete registration packet must include the following correctly executed documents:

• Form AP1 (Application for Registration): Ensure all relevant title numbers (leasehold and freehold) are listed in Panel 2.

• Deed of Surrender and Regrant / Deed of Variation:

  • Must clearly state the extended term and new expiry date.

  • Must reference the date and parties of the original lease.

• Lender Consent / Discharge Documents:

  • If the property is mortgaged, the existing lender’s consent must be lodged to ensure the legal charge automatically attaches to the new extended lease term.

• SDLT5 Certificate or Self-Assessment Document:

  • Required if Stamp Duty Land Tax (SDLT) is payable on the premium or rent, or if an exemption applies and must be formally declared.

• HM Land Registry Fee: Ensure the correct fee under the current Fee Order is included (calculated on the premium paid).

3. Common HM Land Registry Requisitions (And How to Prevent Them)

Failing to handle Land Registry requisitions promptly can have severe financial consequences. In a notable unregistered lease extension warning case study, an unanswered requisition led to cancellation, preventing a subsequent remortgage and resulting in nearly £50,000 in firm liability. it Should also be noted that post-completion accuracy is rapidly becoming the most widely used metric for evaluating conveyancing firm performance. Lenders, regulators and insurers use it to score your firm from publicly available HMLR data. It is possible that lenders are are already scoring your firm via avoidable requisition reports.

4. Post-Registration Verification

Once HM Land Registry completes the application:

1. Inspect the Official Copies: Verify that the lease term on the Register of Title reflects the new expiry date.

2. Confirm Mortgage Charge Annotation: Ensure the lender’s legal charge is correctly registered against the newly extended leasehold title.

3. Notify the Client & Lender: Provide updated title official copies confirming the short lease defect has been legally resolved.
