A personal message, whether sent via WhatsApp, email, or even a handwritten letter, carries no legal standing. A lawyer-drafted legal notice is an entirely different matter. It is issued on advocate letterhead, cites the applicable legal provisions, and creates an official record of your grievance. Courts recognise a properly served legal notice as evidence of a genuine attempt to resolve the dispute before approaching litigation. No personal message carries that weight, regardless of how strongly it is worded.
