The fuller picture
Singapore's Security of Payment Act gives anyone who does construction work or supplies goods or services under a written contract a statutory right to progress payment. The claimant serves a payment claim; the respondent must reply with a payment response within the contract period (maximum 21 days) or 14 days; unresolved disputes go to fast adjudication at the Singapore Mediation Centre, enforceable as a court judgment.
