The judge said that new agreement changed the terms of the old agreement but did not negate the need for him to pay the $200,000.
"The variation agreement provided for what was to happen when the property was sold and how the $200,000 was to be treated. In particular, the agreement provided that the $200,000 was to be paid out of the proceeds of the sale of the property," the judge said.
Unfortunately, the house sale did not realise the sum envisaged, leaving a shortfall once the mortgage and her $350,000 had been repaid.
The wife said he still had to pay the $200,000 but he said his obligation had been extinguished by the new agreement over the house.
In the High Court at Auckland Justice Geoffrey Venning had awarded judgment against the husband.
He then went to the Court of Appeal, but has now lost.
