Section 146 Notices & Lease Forfeiture Explained
Lease forfeiture is a legal remedy available to landlords when a tenant breaches the lease terms. It is typically exercised through peaceable re-entry or possession proceedings and is governed by the Law of Property Act 1925.
What is Lease Forfeiture?
Forfeiture enables landlords to end a lease early due to a tenant’s breach. A forfeiture clause must be included in the lease. Correct legal procedure must be followed, particularly when regaining possession.
Understanding Section 146 Notices of the Law of Property Act 1925
Except for non-payment of rent, a landlord must serve a Section 146 notice before taking enforcement action. The notice must:
- Specify the nature of the breach
- State whether it can be remedied
- Allow a reasonable time to remedy (if applicable)
- Demand compensation if appropriate
Common Breaches That May Trigger Forfeiture
- Non-payment of rent (no Section 146 notice required)
- Unauthorised alterations or structural changes
- Illegal subletting or unauthorised assignment
- Failure to repair, or causing disrepair
- Use of the premises for unlawful activity
Serving a Section 146 Notice
The Section 146 notice must be given in writing and allow the tenant an opportunity to comply. If not complied with, the landlord may proceed with re-entry or apply to the County Court for possession.
Relief from Forfeiture
Tenants can apply to court for relief from forfeiture under Section 138 of the Law of Property Act 1925. Relief is commonly granted if rent arrears are cleared or the breach is remedied quickly. Courts have wide discretion in commercial cases.
