IF I SERVE A SECOND SERVE & IT HIS THE NET & MY OPPONENT CATCHES THE BALL IS IT MY POINT OR DO WE PLAY IT OVER?

The opponent is not supposed to catch the ball unless it has hit out of bounds. A net serve that lands in the service court is a let and is replayed.

If it lands out of the service court it is out and since that was your second serve you double faulted so the point is awarded to the other side.

Guessing that the opponent caught the ball out of bounds but before it hit, he could claim he was just speeding up the game, and you lose, and you can claim that the ball was not out.

If this is just a fun game don't sweat the small stuff and move on, if this is a real game then the umpire will make the call.

In real life the ball is not your point since it was a net serve, but it should be replayed.

**Normally,** during a point, players must let the ball bounce, no matter where they are on the court, even if the player is standing next to the back fence.

"Rule 24. PLAYER LOSES POINT

The point is lost if

.......

i. The ball in play touches the player or anything that the player is wearing or carrying, except the racket;"

However, your question asks about a serve that clipped the net and went over. For this situation, we look at Rule 22.

"Rule 22. THE LET DURING A SERVE

The service is a let if:

a. The ball served touches the net, strap, or band, and is otherwise good; or, after touching the net, strap, or band, touches the receiver or the receiver's partner or anything they wear or carry before hitting the ground;

.....

In the case of a service let, that particular service shall not count, and the server shall serve again, but a service let does not cancel a previous fault."

So, to answer your question, this was a let. You would need to serve again, but this is a *second* serve, so if you served the ball out or into the net, it's a double fault and you would lose the point. Or, getting your serve in, the point continues.
