Identify the mistake before correcting the score
A player saying 'we served from the wrong side' may mean the wrong person served, the server used the wrong service box, or the pairs forgot to change physical court ends. Those are different corrections.
Name the error precisely. In this guide A1 and A2 are partners, and B1 and B2 are their opponents. Keep those labels beside the score while you reconstruct the order; a list of names is more useful than debating who remembers the last rally best.
| What went wrong? | Relevant decision |
|---|---|
| Wrong player is serving | Correct the server; Rule 6.9 |
| Correct player, wrong service box | Correct the box; Rule 6.7 |
| Receivers changed their order | Use the receiving-order provision; Rule 8 |
| Pairs missed an end change | Use the end-change provision; Rule 5 |
