First identify what you are replaying
Three descriptions can sound alike beside a noisy court: the serve touched the net, a player was not ready, or something interrupted an established rally. Start with the event, not with an assumption that every incident means two fresh serves.
The FIP rules separate service replays from point replays and interference. The table is a quick route into those rules. It is not permission to call a let retrospectively after seeing whether your shot wins.
| Situation | Restart |
|---|---|
| Legal net contact on a first serve | Repeat the first serve |
| Legal net contact on a second serve | Repeat the second serve |
| Net contact followed by an illegal service landing or fence contact | A service fault, not a net-service replay |
| A rally interrupted by a point let | Replay the point |
| A disputed interruption | Get the official's decision before changing the score |
