Can one use "you" or "your" when addressing a Prince?

[Dr_metz_livs]

Hey, Am writing a letter to a prince on behalf of some of my students and was wondering whether it is correct to use "you" and "your" when addressing a prince e.g we would be honoured if you would attend? Should it be "Your Highness"? Please help!!!

thanks

Whilst 'Your Highness' or 'Royal Highness' might be correct protocol it can be a minefield if you get it wrong and you can end up looking a real p**t.

There is no substitute for a polite and courteous letter to anybody. I had reason to write to such a person and found a 'Dear Sir' went down very nicely and, was replied to very courteously.

When addressing princes (both in writing letters, and in directly meeting and speaking to them) I have always used "you" and "your" and there has never been any problem in the replies or responses.
