Learn how to challenge unlawful lease forfeiture in England and Wales, including legal protections, Section 146 notice requirements, how to apply for relief from forfeiture, key time limits and practical steps to protect your leasehold rights.

Lease forfeiture is one of the most serious consequences a leaseholder can face. It involves a landlord terminating a lease and seeking possession of the property because the leaseholder has breached one or more covenant terms. While landlords can forfeit a lease in appropriate circumstances, there are strict legal rules governing how this can happen in England and Wales. If these rules are not followed, or if relief from forfeiture is available, the leaseholder may be able to challenge the forfeiture, prevent eviction and potentially have the lease restored. This article explains the legal framework, practical steps, time limits and what protections leaseholders have when faced with unlawful lease forfeiture.
What Is Lease Forfeiture?
Lease forfeiture is a legal mechanism allowing a landlord (or freeholder) to end a lease before its contractual expiry because the leaseholder has failed to comply with important lease obligations. Common grounds include:
- Failure to pay ground rent or service charges;
- Persistent breach of other covenants (such as maintenance or insurance);
- Unauthorised subletting or use of the property.
Forfeiture results in loss of the lease and, in the end, possession of the property. For residential properties, landlords cannot simply re‑enter and evict a leaseholder without a court order, and there are statutory protections in place to safeguard tenants' rights.
Legal Requirements Before Forfeiture
Before a landlord can lawfully forfeit a lease for breach of covenant other than non‑payment of rent, they must comply with the Law of Property Act 1925 (Section 146). This involves:
- Serving a Section 146 Notice on the leaseholder that specifies the breach,
- Requiring the leaseholder to remedy the breach (if capable of remedy),
- Allowing reasonable time to do so, and
- If appropriate, requiring compensation for the breach.
For unpaid rent, a Section 146 notice is not required, but the landlord must still obtain a court order for possession before evicting a residential leaseholder.
In the case of non‑payment of service charges or other sums, forfeiture is only available where:
- The leaseholder has admitted the breach, or
- A court or tribunal (such as the First‑tier Tribunal (Property Chamber)) has determined that the breach occurred. The landlord cannot serve the Section 146 notice until at least 14 days after this determination.
If any of these procedural steps are not correctly followed, the forfeiture may be considered unlawful.
Relief From Forfeiture: A Key Protection
Leaseholders facing forfeiture often have the right to apply for relief from forfeiture, a legal remedy available in the county court or High Court. Relief from forfeiture effectively sets aside the forfeiture and restores the lease, provided certain conditions are met. This relief is based on equitable principles and gives the court discretion to preserve the lease despite a breach.
When Can You Apply?
- After a Section 146 notice has been served but before forfeiture occurs;
- After a forfeiture order has been made by the court;
- In some circumstances, after forfeiture has been peaceably effected (for example, where the landlord has taken possession without a court order).
There is typically a six‑month time limit to apply for relief from forfeiture when the grounds relate to rent arrears. For other breaches, leaseholders should act as soon as possible because delays can prejudice their case.
What Will the Court Consider?
When deciding whether to grant relief from forfeiture, the court will look at:
- Whether the leaseholder can remedy the breach (for example, paying arrears or stopping an unauthorised use);
- Whether the leaseholder has acted in good faith;
- Whether granting relief would be just and equitable in all the circumstances;
- The extent to which the landlord would suffer prejudice from allowing the lease to continue.
If relief is granted, the court will usually impose conditions, such as payment of arrears, interest and the landlord's costs. The leaseholder must comply fully with these conditions to retain the lease.
Practical Steps to Challenge Unlawful Forfeiture
1. Review the Landlord's Notices
Check whether:
- A Section 146 notice was served (if required);
- The notice correctly identifies the breach and required remedy;
- Reasonable time was given to remedy the breach. If not, the notice may be invalid.
2. Respond Promptly and Remedy the Breach
If possible, remedy the breach quickly (for example, by paying arrears or stopping the offending conduct). Even where a dispute exists, taking prompt action may strengthen your position if you later seek relief.
3. Apply for Relief From Forfeiture
If forfeiture proceedings have been raised or a forfeiture order obtained, apply to the county court for relief from forfeiture without delay. Provide evidence that you have remedied or can remedy the breach, and that granting relief is fair in all the circumstances.
The court's approach is discretionary but generally considers relief where the leaseholder has acted promptly and shown willingness to comply with the lease in future.
4. Seek Legal and Professional Advice Early
Lease forfeiture and relief from forfeiture involve technical legal procedures with strict time limits. Early guidance from a solicitor experienced in leasehold disputes can be critical, especially where possession proceedings are underway.
Common Scenarios Where Forfeiture Is Unlawful
Forfeiture can be challenged as unlawful where:
- The landlord failed to serve a valid Section 146 notice where one was required;
- The landlord did not await a tribunal or court determination of a disputed breach before serving the notice;
- The landlord's conduct amounts to waiver of the right to forfeit, such as by accepting rent after knowledge of the breach;
- No court order for possession has been obtained in respect of residential property.
In these cases, a leaseholder may be able to have forfeiture set aside and retain their lease.
Risks and Time Limits
- Delays reduce your chances of obtaining relief from forfeiture; prompt action is essential.
- Relief applications often require evidence of compensation paid or offered to the landlord. Failure to pay amounts due can weaken the application.
- Legal costs can be significant; many leaseholders consider specialist legal representation essential to navigate these disputes.
Key Takeaways

With the right steps and timely action, leaseholders facing forfeiture can challenge unlawful attempts and protect their interests.
