What Evidence Should A UK Commercial Landlord Gather Before Serving A Forfeiture Notice?

Before preparing a commercial lease breach or forfeiture notice, the landlord should align the evidence with the specific covenant breached. For non-payment of rent, keep a rent ledger, invoices, demands and bank records. For disrepair, alterations, unlawful use or nuisance, keep dated inspections, photographs, expert reports and correspondence showing the tenant was told about the issue.

Why Does The Lease Matter Most For A Notice Of Forfeiture?

The lease is the starting point because it identifies the premises, parties, forfeiture clause, covenants, rent dates, permitted use, repair obligations and any notice service rules. Evidence should use the same names, dates, address and breach wording as the lease and any licence, deed of variation or side letter.

When Is A Section 146 Notice Evidence Checklist Needed?

For most breaches other than non-payment of rent, section 146 of the Law of Property Act 1925 requires a notice specifying the breach, requiring remedy if capable of remedy, and requiring compensation if sought. Evidence should therefore show what the breach is, whether it can be remedied, what remedy is required, and how any compensation figure was calculated.

How Can Evidence Reduce Risk When Drafting A Commercial Eviction Notice?

  • Use dated records: inspection notes, photographs and reports should show when the breach existed.
  • Check sums carefully: arrears schedules should separate rent, VAT, service charge, insurance rent, interest and costs.
  • Preserve communications: emails and letters can show knowledge, warnings, admissions, waiver risk and opportunities to remedy.
  • Keep original source documents: leases, licences, plans, consents and expert reports should be stored with the draft notice file.
  • Confirm service details: use the lease notice clause and any current company or individual address checks before serving.
