Ground 12 is a discretionary possession ground for breach of tenancy agreement obligations (other than rent payment). Common breaches: unauthorized pets, subletting without permission, business use, excess occupants, or failure to maintain the garden. From May 2026, tribunals will require clear evidence the breach is material (not trivial), ongoing or repeated, and that you warned the tenant. The tribunal decides if possession is reasonable.

Ground 12 is a discretionary possession ground for breach of any tenancy agreement term except rent payment (rent arrears are covered by other grounds). Common breaches: unauthorized pets, subletting, running a business from the property, causing damage, or failing to maintain gardens. The breach must be material (serious), not trivial. Tribunals decide if possession is reasonable.
Any breach of a tenancy term except rent. Common examples: keeping pets when prohibited, subletting without permission, more occupants than allowed, using property for business, parking violations, failure to maintain property (if tenant responsibility), smoking when prohibited, or alterations without consent. The breach must be in the written tenancy agreement.
It's not legally required, but strongly recommended. Tribunals are more likely to grant possession if you: (1) warned the tenant about the breach in writing, (2) gave them time to remedy it, (3) showed they failed to remedy or repeated the breach. Immediate possession action for first minor breach may be considered unreasonable.
Tribunals will likely refuse possession for trivial breaches. Example: parking 6 inches outside designated spot would be too minor. Keeping 10 dogs in a no-pets property would be material. The breach must be serious enough to justify eviction. Tribunals balance the breach against the tenant's right to housing.
