@StrixUralensis It's "I Am Not A Lawyer". It's usually used when giving advise and suggestions that borders on law, since many countries have provisions against giving law-related advises.
Another one is TINLA, short for "This Is Not Legal Advice".
Supporedly, saying either or both IANAL and TINLA prevents potential problems if what you said ended up damaging someone. I'm not sure, but I think those two are the only court recognized "disclaimers". 🤣
