Adverse possession: possession
There is no adverse possession where there is insufficient evidence of possession itself (Tang Ching v Wu Wan Yau)
Leases: essential elements
When seeking to argue that an agreement (perhaps disguised as a partnership or employment agreement) gives rise to a lease, the would-be tenant must identify and prove the demised premises, the term and the intention to create a lease with the necessary degree of certainty and on the balance of probabilities (Chau Yu v Kwan Chuen Kuen (No 2))
Leases: exclusive possession
There is no exclusive possession where the purposes underlying the agreement could not be achieved if the occupier had exclusive possession nor wherethe restrictions imposed on the occupier are incompatible with exclusive possession (Westminster City Council v Clarke)
