The applicant sought rectification of a 2006 divorce order that omitted agreed corollary relief, including $100,000 in support arrears and ongoing support, after solicitor error resulted in a divorce simpliciter.
Following a trial directed on the factual dispute, the court found a sufficient common intention between the parties to support rectification and held that Rule 25(19)(b) permits amendment where an order contains a mistake arising from inadvertent omission.
The court rejected arguments based on solicitor negligence, delay, laches, and res judicata, finding no prejudice sufficient to bar equitable relief.
After crediting specified payments made since the order, the court fixed remaining support arrears at $51,392.11.
