# Casualty clause

*Legal · Global*

## Short definition

Lease terms governing damage and rebuild after a fire/disaster.

## Full definition

Specifies whether the landlord must rebuild, how long abated rent runs, and when either party may terminate. Highly negotiated in [Class A](/glossary/class-a); tenant wants a hard 12-month terminate-if-not-rebuilt right.

## Why this matters for Class A leasing

Casualty clause is part of the legal vocabulary that institutional Class A occupiers, landlords, and advisers use across Global markets. Understanding it correctly affects how you read lease documents, model occupancy economics, and benchmark deal terms across cities. Class A Atlas tracks regional variation alongside the global standard so [cross-border](/topics/cross-border-expansion) occupiers can translate quickly.
