If I said I was an expert in my field is that legal? -

if i said i was the expert in car repair is that legal We ARE the experts in auto repair! that was the quote i was going to use

Yes it s legal. Saying you re an expert at something isn t really quantifiable, so technically everyone can make up their own definition. There s really no legal difference between your quote and saying We re the best in auto repair! You can t prove you re an expert, but since there s no legal definition, no one can say you re not an expert.

It s fine. I do it all the time.
