2. What are the consequences of failing to stamp a tenancy document?
An obvious consequence is that the landlord and the tenant will be liable to civil proceedings by the Collector of Stamp Duty of the Inland Revenue Department. Moreover, a tenancy document must be stamped before it can be lodged with the Land Registry for registration.
A more important consequence is that the Court may not accept an unstamped tenancy document as evidence in civil proceedings. In other words, a party will have difficulties in enforcing the tenancy document against the other party (who has breached the Tenancy Agreement or Lease) in Court.
