Parminder Mattoo acted for the appellant in a long-running family property dispute concerning the beneficial ownership of residential property, which culminated in a successful appeal to the High Court (Chancery Division).
The appeal addressed whether an alleged oral agreement, said to have been reached years after acquisition, could lawfully alter beneficial ownership under an existing constructive trust. The case required the Court to consider the interaction between informal family arrangements, the statutory requirements governing dispositions of equitable interests, and the evidential threshold required to establish a new constructive trust.
Parminder instructed James Sandham of Selborne Chambers to appear on the appeal. The High Court allowed the appeal, confirming that agreement alone is insufficient: where beneficial interests are said to have changed, there must be clear post-agreement conduct amounting to substantial detrimental reliance. The Court also reaffirmed that statutory formalities continue to apply unless a new constructive trust arises by operation of law.
The decision overturned the first-instance finding and provides important guidance in cases where historic oral arrangements are relied upon to displace established property rights.
