A doubles service mistake can cost more than a point. A foot fault gives away a fault, a missed service-order change can confuse the whole team, and serving to the wrong box gives your opponents an easy chance to take control. Most of these problems are preventable once you know which rules apply to the server, the serving partner, and the receivers.
The key difference from singles is coordination: doubles teams must keep a legal serving order and a legal receiving order while still covering the court. Here are the most common tennis doubles serving mistakes, what the rules say, and how to avoid them.
1. Serving from the wrong side or to the wrong box
Every game starts with a serve from the deuce side, and the server switches sides after each point. The serve must travel diagonally into the service box opposite the server. On a deuce-court point, for example, the server aims for the receiver’s deuce-side service box.
In doubles, the service boxes are the same size as in singles. The doubles alley is not part of the service box, so a serve that lands in the alley is a fault. Once the serve has bounced in the correct service box, however, the doubles alley becomes part of the court for the rally.
How to avoid it: Before serving, check the score and call it clearly. The score helps both teams keep track of which side to serve from. If you’re unsure, pause and confirm the score rather than guessing.
2. Losing track of the doubles serving order
At the start of each set, each team chooses which partner serves first. The players then take turns serving in an order that continues through the set. For example, if Team A’s players are A1 and A2, and Team B’s are B1 and B2, the order might be A1, B1, A2, B2. The same sequence continues until the set ends.
A common mistake is for one partner to serve twice in a row because the team forgets whose turn it is. If the wrong player starts serving, tell the official as soon as you notice. Under the rules, the correct order is restored when the mistake is discovered, but points already played generally stand. If the mix-up isn’t noticed until after a game is complete, the service order usually remains as played for the rest of that set.
How to avoid it: Agree on the serving order before the set and use a quick reminder between games. A simple signal or a quiet “you’re next” can prevent confusion without delaying play.
3. Standing on or over the baseline
A server commits a foot fault if, during the service motion, a foot touches the baseline, the court inside the baseline, or the wrong area outside the serving position. Stepping on the line before striking the ball can be a fault even if the serve lands perfectly.
Foot faults often happen when a player rushes, drifts forward, or starts with their back foot too close to the baseline. They count as service faults just like a serve that lands out.
How to avoid it: Set your feet behind the baseline before starting your motion. If you tend to creep forward, leave a little extra space behind the line and practise serving at match pace while keeping your feet still until contact.
4. Serving from the wrong position in the rotation
In doubles, the serving team’s partners do not need to stand in fixed spots during a point. But the server still needs to serve from the correct side for the score, and both teams must preserve the established serving and receiving order.
For instance, a player who is meant to serve from the ad court might begin on the deuce side because the score was called incorrectly. The team may then notice the error only after the point. Stop play and ask the official to clarify the score and position rather than carrying on with a guessed arrangement.
How to avoid it: Let the score determine the server’s side, not a partner’s preferred formation. Before each point, the server can call the score and check that both teams are ready.
5. Mixing up the receiving order
At the start of each set, the receiving team chooses which partner will receive the first point from the deuce court and which will receive first from the ad court. Those positions stay in place for that set: the partners alternate receiving sides as the points progress.
A receiver can stand anywhere on their side of the net while the serve is being struck, but the designated partner must take the return from the correct side. If the wrong partner returns a serve, the mistake can cost the team the point. The receiving positions can be changed for the next set, not partway through the current one.
How to avoid it: Decide who takes each side before the set begins. If you use a planned formation, make sure it does not leave both partners unsure about who is responsible for the return.
6. Treating a let or a missed toss incorrectly
If a serve touches the net and then lands in the correct service box, it is a let and the server plays that serve again. A let does not count as a fault. But if you swing at the ball and miss, that is a fault—even if you barely touched it.
If you toss the ball and decide not to hit it, you may catch it or let it bounce, then begin again. That is different from swinging and missing. Players sometimes rush after a poor toss and turn a harmless reset into a fault.
How to avoid it: If the toss is clearly off, stop your motion and reset rather than chasing it. Make sure your partner and the receivers are ready before beginning another attempt.
7. Forgetting that the serving partner can cause a hindrance
The server’s partner may stand in different areas of the court, including near the net, but should not deliberately distract the receivers. Deliberate actions that interfere with an opponent—such as shouting or making a sudden movement to disrupt a return—can be ruled a hindrance.
Normal positioning and movement are part of doubles, of course. The issue is deliberate distraction, not simply standing in the receiver’s line of sight. Partners should focus on useful signals and court coverage, not trying to unsettle the returner unfairly.
Quick doubles serving check
| Before the serve | Check |
|---|---|
| Score and side | Are you serving from the correct side and aiming diagonally? |
| Serving order | Is it your turn to serve in the agreed sequence? |
| Receiving order | Is the correct receiver set to take this point? |
| Feet and readiness | Are your feet behind the baseline, and are the receivers ready? |
Frequently Asked Questions
Can the server’s partner stand anywhere during a doubles serve?
Generally, yes. The partner can choose a position on their team’s side, but must not deliberately distract or hinder the receivers. The server still has to follow the serving rules and serve to the correct box.
Can doubles partners change who serves during a set?
No. The team’s serving order is set at the start of the set and continues through it. The partners can choose a different serving order for the next set.
Can doubles partners switch receiving sides during a set?
No. The receiving order is chosen at the start of the set and stays in place for that set. The partners may choose different receiving positions for the next set.
Is a serve that clips the net always replayed?
No. It is a let only if it touches the net and then lands in the correct service box. If it lands outside the box, it is a fault.
Final Thoughts
Most tennis doubles serving mistakes come from rushing or losing track of the order—not from a difficult rule. Agree on serving and receiving positions before each set, call the score, and take a moment to check the correct side before every point. That small routine helps your team avoid needless faults and focus on the tactics that win the rally.
