My husbands ex-wife posted nasty things about him online, saying that he's a drug addict and and a pedophile, which of course non of it is true, so we're thinking to sue her for defamation of character, but is it possible, since she posted it online and there's no real way to prove that its her
Would appreciate any advise
Thank you
