#Key legal issues
#Adverse possession - whether the Plaintiff's occupation was hostile with animus possidendi
No; her occupation was based on a mistaken belief that the land was within her boundaries, lacking the intention to possess and exclude the true owner
The Plaintiff and her brother confirmed she only learnt in 2022 that the portion might belong to another person. Prior occupation rested on a mistake of boundaries. Further, she adduced no survey evidence showing the 0.49 ha she occupied fell within Parcel No. 735. Without animus possidendi and proof of dispossession of the titled owner, the claim fails.
Alternative claim of constructive trust under Section 28(b) of the Land Registration Act
Rejected; long occupation alone does not create a constructive trust
The court applied the Supreme Court's decision in Shah v Mombasa Bricks & Tiles: a constructive trust arises only from clear acts or circumstances showing it would be inequitable for the registered owner to deny another's interest or to prevent unjust enrichment. No relationship or prior dealings between the Plaintiff and the deceased proprietor before 2000 were proved.
Whether the Plaintiff proved the extent and location of her encroachment on Parcel No. 735
Not proved; an unresolved boundary dispute existed and no evidence located the claimed portion within Parcel 735
The Defendant's evidence showed the boundary between Parcels 735 and 3325 was unidentifiable and a boundary re-establishment process was underway when the suit was filed. The Plaintiff produced no surveyor's evidence or proof that her developments fell within the disputed portion of Parcel 735.
