I have never seen any player change hands during a point, or even during a match, or even during a career. But is it illegal?
Don't take my word as law. http://www.bwfbadminton.org/page.aspx?id=14915 Check through for yourself if you like. It MIGHT (although I'd be hard pressed to see why it would) fall into distracting the opposition. It could even be banned in higher level tournaments. I couldn't really say on stuff like that.
I've done it during club nights as I am ambidextrous and can play with both hands It is perfectly legal but I don't do it in league matches as it is slightly slower and I find it harder to change my footwork to match as I am used to playing right handed mostly.

I remember this exact same question being asked at my umpire training course. The instructors (two experienced umpires (I/N)) concurred that it's completely legal. You may not, however, play with two rackets at once. One of my coaches is slightly ambidextrous and is about one or two (out of 10) leagues worse when playing as a leftie. That's great for coaching left-handers, but he also sometimes switches (for a whole match) to balance out a training game. And I've seen a beginner who served with right but played with left . Fortunately, this does not ever happen in high-level player (i.e. with umpires).
I've known a player who would change his handedness when hit to his backhand side. Don't think it's illegal, but way too slow in a high paced doubles game.
I do exactly the same thing when coaching Left handers as I can demonstrate effectively with my left hand, it has it's uses. Kindest regards, -Ajay- Quote of the Day A wide screen just makes a bad film twice as bad.
