One of my not-so-close family relative has posted my Personal pics on our Family Group (imm. Family & close Cousins) in WhatsApp with the intention to defame me. He got the photos from somewhere and posted them depicting his own story out of it, which is completely False. He has shared these without knowing a single fact about them, when where etc. those were taken. His act has hampered my reputation and peace within Family. Please advise if I can sue him for defamation and section 504?
