When may an indoor-volleyball player reach beyond the net or cross the centre line into an opponent’s space?
The FIVB indoor rules allow some movement into an opponent’s space, but the conditions differ by action. A blocker may touch beyond the net after the opponent executes an attack if there is no interference; an attacker may follow through after making initial contact in their own space. Under the net, entry must not interfere, and a penetrating foot must retain part of itself on or directly above the centre line. A fully penetrating foot is a fault.
For Viewers interpreting player intrusion into opponent space, rather than the ball’s crossing route. · Updated
Blocking and attacking use different timing tests
For a block, a player may touch the ball beyond the net only if the player does not interfere before the opponent executes the attack hit. Reaching over early and touching the ball before that attack is a fault.
After an attack hit, a player may pass a hand beyond the net when the initial contact was made in the player’s own playing space and the ball was not caught or thrown. This is a follow-through rule, not permission to make the initial hit in the opponent’s space.
Under the net, interference and foot position matter
Penetrating into the opponent’s space under the net is allowed when it does not interfere with the opponent’s play. To touch the opponent’s court with a foot, some part of the penetrating foot must remain touching or directly above the centre line, and the action must not interfere. A foot that penetrates completely into the opponent’s court is a fault.
A body part above the feet may touch the opponent’s court if it does not interfere. The rule treats this differently from a foot, so do not apply the centre-line foot test to every body part.
The free-zone and out-of-play clauses are separate
A player may enter the opponent’s court after the ball goes out of play. Entry into the opponent’s free zone is permitted if it does not interfere. These clauses concern player movement; whether a ball can cross outside the antenna or be recovered is a different question.
Apply the named indoor edition
This guide uses FIVB Official Volleyball Rules 2025–2028, listed as the current English edition on the FIVB site and stated to apply to competitions beginning after January 1, 2025. The 2026 announcement covers selected tests in named event groups; it does not establish that every competition adopted a test or later instruction.
Four fictional player-space branches
A fictional blocker reaches beyond the net before the opponent attacks and touches the ball; the timing condition is not met. In a separate branch, an attacker first contacts the ball in their own space and then follows through with a hand beyond the net without catching or throwing it. Under the net, one player’s foot reaches into the opponent’s court while part remains touching or directly above the centre line and does not interfere; a fully penetrating foot is treated differently. A hand or arm above the feet may touch the court only if it does not interfere. These examples do not decide net-contact or ball-recovery questions.
Related questions
Can a blocker touch the ball on the opponent’s side before the attack?
Not before the opponent executes an attack hit. The blocker also must not interfere with the opponent’s play.
Does every foot crossing the centre line cause a fault?
No. The rule allows court contact when part of the penetrating foot remains touching or directly above the centre line and there is no interference. Complete penetration of the foot is listed as a fault.
Does this rule decide whether a ball outside the antenna is playable?
No. This guide covers player-space intrusion. Ball crossing and recovery have separate conditions.
