The ball is in your court.
The ball is in your court.
The phrase 'The ball is in your court' is a popular idiom derived from tennis or other net sports, where hitting the ball back over the net puts the play into the opponent's side of the court. In everyday use, it means that someone now has the responsibility to make the next move or decision in a situation. Think of it as though someone has passed you the 'ball' (or responsibility), and it's up to you to decide what to do with it. This idiom is often used in contexts where decisions need to be made after someone has given you the power or after they have done their part.
