To qualify for entitlement under section 3A of the Deceased Estates Succession Act [Cap 06:02], a surviving spouse must have actually been living in the house or domestic premises 'immediately before' the deceased's death. The word 'immediately' means at the time of, or just before, death and requires an actual factual connection between the surviving spouse and the residence at that specific time. The provision does not extend to properties the parties intended to live in, previously lived in, or owned but did not occupy at the time of death. The legislative purpose of section 3A is to prevent surviving spouses from being uprooted from their actual residences, not to grant automatic inheritance of all immovable property owned by the deceased.
