Breaking a commercial lease can lead to legal disputes between landlords and tenants. If a tenant fails to comply with the lease terms, the landlord may pursue legal action to recover financial losses resulting from the breach. This could include: 

• Law suit for unpaid rent: The landlord can sue to recover unpaid rent, legal fees, and other related damages.
• Specific performance: In some cases, the landlord may seek a court order requiring the tenant to fulfill their lease obligations. 
• Eviction and repossessions: The landlord may initiate legal proceedings to evict the tenant and regain control of the premises.
• Loss of security deposit: The tenant may forfeit their security deposit if the breach results in damage or financial loss.

These consequences depend on the lease terms and local laws, and both parties are encouraged to seek legal advice or explore dispute resolution methods before escalating to court.
