The rules of intestacy would apply in this scenario, as the deceased has died intestate, which means with no valid Will. The intestacy rules only apply to property that the deceased was able to dispose of by their Will if they had held a valid Will. It does not extend to property held as joint tenants or under interest under a trust. It is important to seek legal advice on who would inherit the estate, as particularly in this scenario, it is dependent on numerous factors, including, but not limited to, the estate value and the date of death.
