A Goldman Sachs banker who spent thousands from a joint marital account on his secret mistress has been ordered to pay back £4 million after a bitter divorce battle. Ardal Loh-Gronager, 35, married businesswoman and heiress Wei-Lyn Loh in 2019 and quit his job to support her and oversee the refurbishment of their Primrose Hill mansion.
The couple split in 2023 after it emerged that Loh-Gronager was having an affair, described in High Court papers as 'expensively financed' and 'parallel to his marriage'. He paid his mistress from the joint account, often disguising payments as 'flowers', and allowed her to use his £200,000 Bentley, a pre-marriage gift from his wife.
Under a prenuptial agreement, Loh-Gronager was set to receive over £6.4 million. However, his ex-wife dragged him to court, arguing he had already taken about £4 million from the joint account. The court heard he also transferred £1 million from his wife's account on the day she was undergoing therapy.
Mr Justice Cusworth ruled that Loh-Gronager's payout should be reduced to £2,369,385, citing the sums he had already taken and his 'callous' conduct, including doctoring emails and harassing his ex-wife. The judge said Loh-Gronager had 'been preparing the ground for as lucrative a separation as he could contrive'.
