Rotation fixes the order; overlap is a foot-position fault.

The ruleset used on this page

This page covers six-player indoor volleyball under the FIVB Official Volleyball Rules 2025-2028, approved by the 39th FIVB World Congress and implemented in competitions beginning after 1 January 2025. The controlling provisions are Rules 7.3-7.7 and 12.2-12.7.

It does not state a universal rule for beach volleyball, NCAA, NFHS, national federations, recreational leagues or age-grade modifications. A limited FIVB 2026 trial is identified separately below because its timing differs materially from standard Rule 7.4.

Rotation, position and tactical formation are not the same

• Rotational order is the six-player sequence submitted in the starting line-up. That sequence remains in force throughout the set, subject to legal substitutions and Libero replacements.
• Position, often called overlap, is the receiving team's relative arrangement at the rulebook's judging moment. It is not a requirement to stand on six fixed marks.
• Tactical formation is where players go after the service hit to set, attack, block or defend. A setter may begin in the back row for rotational purposes and run to the net without becoming a front-row player.

When a team rotates—and when it does not

FIVB Rules 7.6.2 and 12.2.2 set the clockwise sequence. When the receiving team wins a rally and gains the right to serve, position 2 moves to position 1 to serve; 1 moves to 6; 6 to 5; 5 to 4; 4 to 3; and 3 to 2.

If the serving team wins the rally, it does not rotate: the same player, or that player's legal substitute, serves again. Rotation occurs on gaining service, not after every point and not merely because a coach wants a different matchup.

The serving and receiving teams have different duties

At the service hit, Rule 7.4 requires every on-court player to be within that player's own court, except the server in the service zone. The receiving team must also be in rotational order. The serving team, however, may occupy any position at the hit; its players do not commit a relative overlap merely by crossing their rotational neighbours.

This serving-team freedom is easy to miss. It does not excuse a wrong server, a player standing outside the court, a screen, or an illegal substitution. Those are different faults with their own tests.

Which receiving players are compared

Facing the net, the front row is position 4 on the left, 3 in the centre and 2 on the right. The back row is position 5 on the left, 6 in the centre and 1 on the right.

• Front-back pairs: compare 4 with 5, 3 with 6, and 2 with 1. Each back-row player must preserve a legal relationship behind the corresponding front-row player.
• Within the front row: preserve the lateral order 4-3-2.
• Within the back row: preserve the lateral order 5-6-1.

Do not compare every player with all five teammates. For example, position 5 has a front-back relationship with 4 and lateral relationships within the 5-6-1 row; it has no direct overlap test against position 2.

Level can be legal; there is no minimum gap

Rule 7.4.3 determines position from the feet touching the ground. For a front-back pair, the back-row player is legal if at least part of one foot is level with or farther from the centre line than the front foot of the corresponding front-row player. Laterally, each left- or right-side player must have at least part of one foot level with or closer to that player's sideline than the foot farther from that sideline of the other players in the same row.

That wording matters. Players do not need daylight between their shoes, and a whole body leaning across a teammate does not by itself create a positional fault. If a player is airborne at the service hit, the rule says the last contact with the floor fixes that player's position.

The service hit is the legal dividing line

Under standard FIVB Rule 7.4, the receiving team's relative order is judged when the server hits the ball—not at the first referee's whistle, the toss, take-off or landing. Players may anticipate and move before contact, but they must still satisfy every required foot relationship at contact.

After the hit, Rule 7.4.4 allows both teams to move around and occupy any position in their court and free zone. A player who leaves a legal relationship immediately after contact has not committed overlap; later actions are judged under the rules for playing the ball, attack, block and court position.

Some FIVB events release receivers earlier

On 27 February 2026, the FIVB Board of Administration announced a free-positioning test for the 2026 Volleyball Nations League, FIVB Volleyball U17 World Championships and 2026 Continental Championships. In those events, the receiving team must be in correct rotational order at the referee's whistle but may leave that position when the server's action begins—defined by FIVB as the first serving motion, including a step or movement of the arms or legs.

This is a competition test, not a general amendment to the 2025-2028 rulebook. The FIVB notice says any rulebook update remains subject to review. Outside the named tests, use the service-hit timing unless the appointed competition's published regulations expressly adopt another rule.

Which fault wins when the serve is also bad?

FIVB Rules 7.5.2-7.5.3 and 12.7 decide the sequence:

• If the server commits a fault at the service hit—such as improper execution, a foot fault or wrong rotational order—that serving fault is counted before a receiving positional fault.
• If the service is executed correctly but becomes faulty afterward, such as by landing out, the receiving positional fault occurred first and is sanctioned.

The referee therefore does not simply award the rally to whichever fault looks more obvious on replay. The time and type of each fault determine priority.

An overlap fault costs a point and service

For a positional fault, Rule 7.5.4 awards a point and service to the opponent and requires the players' positions to be corrected. The sanction does not depend on whether the receiver passed the ball successfully or whether the out-of-position player touched it.

A position is not made legal by a favourable rally outcome. The fault exists at the designated judging moment; the whistle may come just after the hit because the official first has to identify it.

A rotational fault has additional scorekeeping consequences

Rule 7.7 treats service by the wrong player as a rotational fault, not as an overlap. The opponent receives a point and next service, and the faulty team's order is corrected. If the fault is identified only after the rally that began with it, the opponent still receives only one point for that fault, regardless of the rally result.

The scorer should determine when the wrong order began. If that moment is known, every point subsequently scored by the team at fault is cancelled while the opponent's points remain. If the moment cannot be determined, no earlier points are cancelled; the point-and-service sanction is the only score adjustment.

Substitutes and the Libero inherit a rotational slot

A legal substitute occupies the replaced player's place in the service order. Under FIVB Rule 19.3, a Libero may replace a player in a back-row position; the Libero replacement does not create a new seventh place in the order. The Libero can be replaced only by the regular replacement player for that position or by the second Libero, as the rule permits.

Under FIVB Rule 19.3.1.3, the Libero may not serve, block or attempt to block. A different competition's Libero provisions should not be imported into an FIVB ruling.

If play restarts with a player on court through an illegal substitution, Rule 7.5.1 records a positional fault but applies the consequences of the illegal substitution. It is not treated as an ordinary overlap with only the Rule 7.5.4 correction.

How to rule on a rotation replay

1. Name the ruleset and event. Decide whether standard FIVB 2025-2028 or the named 2026 trial controls.
2. Check the server. Confirm the player matches the recorded service order.
3. Choose the judging instant. Standard rule: service hit. Trial event: correct order at the whistle, then release on the first serving motion.
4. Check court boundaries. Every on-court player except the server must be within that player's own court.
5. For the receiving team, compare the feet. Test 4/5, 3/6 and 2/1 front-to-back, then 4-3-2 and 5-6-1 laterally.
6. Allow level positions. Do not invent a minimum separation or judge torsos.
7. Apply fault priority and outcome. Distinguish a positional fault from a wrong server and from a service that becomes faulty later.

The back-row setter leaves too soon

Situation: under standard FIVB 2025-2028 rules, a receiving setter in position 1 runs toward the net. At the service hit, both of the setter's feet are closer to the centre line than the front foot of the position-2 player.

Ruling: positional fault. Position 1 no longer has any part of a foot level with or farther from the centre line than position 2's front foot. The opponent receives a point and service under Rule 7.5.4.

Two shoes are exactly level

Situation: at the service hit, part of position 6's foot is level with position 3's front foot. Every other required relationship is legal.

Ruling: play on under FIVB 2025-2028. Rule 7.4.3 expressly permits the relevant part of the back-row player's foot to be level. “Overlap” does not mean the shoes need visible separation.

The left receiver crosses completely past the centre receiver

Situation: under standard FIVB 2025-2028 rules, position 4 moves so far right that, at the service hit, neither foot has any part level with or closer to the left sideline than the position-3 player's foot farther from that sideline.

Ruling: positional fault. The 4-3-2 lateral order has been broken under Rule 7.4.3.2. Body contact or a large gap is unnecessary; the feet decide the relationship.

The serving setter crosses teammates before contact

Situation: the correct FIVB server is in the service zone. A serving-team setter crosses in front of two teammates before the service hit; all five non-servers remain within their own court.

Ruling: no relative-position fault under FIVB 2025-2028. Rule 7.4 frees the serving team to occupy any position at the hit. Check separately for screening, a player outside the court or another service fault.

An airborne receiver left the floor legally

Situation: a receiving player jumps from a legal rotational position and is airborne when the server hits the ball, then lands across a teammate's line.

Ruling: no positional fault on those facts. Under Rule 7.4.3, the last floor contact fixes an airborne player's position, and movement after the service hit is unrestricted by the overlap rule.

The same early move in two different 2026 matches

Situation: receivers are correctly ordered at the whistle. They break that order on the server's first arm movement and are crossed before ball contact.

Standard FIVB 2025-2028 ruling: positional fault, because the order was not legal at the service hit. Named 2026 trial-event ruling: legal release, because the players moved only after the first serving motion. The competition identity changes the answer.

Four shortcuts that produce the wrong call

• “Both teams are checked for overlap.” Under current FIVB Rule 7.4, only the receiving team has the relative rotational-position duty at the service hit.
• “A back-row player crossed a front-row player's shoulders.” The position test uses feet, not shoulders or hips.
• “Players rotate after every rally.” A team rotates only when it gains the right to serve.
• “Wrong server and overlap are the same fault.” They trigger different correction and scorekeeping procedures.

Checked on 28 August 2026 against the current FIVB 2025-2028 rulebook and the later 2026 test announcement. The service-hit test is the international baseline; the earlier-release trial is limited to the competitions named by FIVB. Other federations and competitions may publish different line-up, Libero or review procedures.
