On Thursday, Justice Choo Han Teck ruled in favour of the couple and found that the conduct of the agent Jeremy Ang and his boss, Mike Parikh, amounted to breach of duty and fraud.
The two men were "ethically wrong and in breach of contract by reason of creating a conflict of interest between their client and themselves", said the judge.
When a property agent is engaged to sell or buy property, he has a responsibility to act in the interests of the person who hired him - not his own, or his friends', or his relatives' or his boss', said the judge.
