18. Remuneration for professional engineering services

Subject to the provisions of this Act, a person is not entitled to demand, claim or sue for or recover any charge, fee or remuneration for any professional engineering services supplied by the person in Singapore, or for any offer by the person to supply professional engineering services in Singapore, in connection with any arbitration, suit or matter, unless the person supplying or offering to supply professional engineering services is authorised by this Act to supply those services.

Any person, who has made any payment to another person for that other person engaging in conduct which is in contravention of section 15, may recover the money in a court of competent jurisdiction if the person did not know or have reason to believe, when making payment, that the conduct by that other person was in contravention of that section.[12
