Yes, a letter of demand can be used as evidence in court proceedings in Singapore. When a dispute escalates to the point of litigation, any written correspondence, including a letter of demand, can be presented as evidence to support your claims and demonstrate the steps taken to resolve the matter amicably.
It is vital to ensure that your letter of demand is accurately drafted, factual, and professionally presented, as it may be scrutinised during legal proceedings. While a letter of demand itself may not guarantee a favourable outcome or commence legal action to commence legal proceedings, it can serve as a valuable piece of evidence in Court, showcasing your intentions, position, and efforts towards resolving the dispute.
