Tennis coaching rules changed permanently on 1 January 2025, ending roughly a century in which talking to your coach during a match was, at least on paper, cheating. The change was smaller than it sounded and more complicated than most summaries suggested, because the rule that replaced the ban does not actually say coaching is allowed. It says each tour gets to decide.
What Rule 30 covers
Rule 30 of the ITF Rules of Tennis defines coaching broadly: communication, advice or instruction of any kind, by any means, to a player. The breadth is deliberate. It is what allowed chair umpires to penalise a raised hand or a nod from a player box in the years when the rule was a prohibition, and it is why arguments about whether a particular gesture counted were so frequent.
The definition did not change in 2025. What changed was the permission attached to it.
What changed in 2025
National Association delegates voted the amendment through at the 2024 ITF Annual General Meeting in Hong Kong. From 1 January 2025 the rule reads, in summary:
- Coaching from an off-court location may be permitted by the sanctioning body of the event.
- In team events only, where a team captain sits on court, that captain may coach at times the sanctioning body permits.
- In all other competitions, on-court coaching remains prohibited.
- Sanctioning bodies may allow players to access approved Player Analysis Technology at times when coaching is permitted.
Note the phrasing of the first line. The ITF did not legalise off-court coaching everywhere; it gave every sanctioning body the power to legalise it in its own competitions. A permissive framework, not a uniform one — which is why the details still differ between an ATP event, a WTA event and an ITF World Tennis Tour event, and why a coach who knows the rules at one tournament cannot assume they apply at the next.
The on-court exception for team captains is the reason competitions like the Davis Cup look so different from a regular tour event, with a captain seated courtside talking a player through changeovers. That is not a relaxation of the rule; it is written into it. Our guide to team tennis competitions covers the formats where it applies.
When a coach may speak
Where coaching is permitted, the timing rules are consistent. Coaching is allowed between points, at change of ends and at set breaks, plus any other moment the sanctioning body chooses to allow — with one absolute exception. Coaching during the playing of a point is never permitted.
Off-court coaching must also be brief and discreet, except during breaks in play, where the brevity requirement relaxes. In practice this is the difference between a few words as a player walks past the box and a tactical conversation at a changeover.
Why hand signals are treated differently
This is the part most viewers get wrong, and it follows directly from the geometry of a tennis court. Verbal coaching is permitted only when the coach and the player are at the same end of the court. Hand signals are permitted at any time coaching is allowed, regardless of which end the player is standing at.
The reason is audibility. A coach shouting from a box at the far end has to raise their voice enough that the opponent hears it too, which turns coaching into a hindrance and gives one player information about the other’s tactics. A gesture carries to one person. So the rule permits the silent channel continuously and restricts the audible one to the half of the court where it cannot spill over.
It also means a player at the wrong end who wants information has to wait for the changeover, which is why you see players glance at the box on the walk rather than during the game.
What each tour still decides for itself
The ITF left a long list of decisions to individual sanctioning bodies, and this is where most of the practical variation lives:
- Whether coaching is permitted at all in its events
- Whether a chair umpire must be present for coaching to be allowed
- Whether both players must have a coach present for either to be coached
- Who may coach — whether coaches must be qualified or accredited
- How many people may coach a single player
- Where those people must be located
- Who polices the rules: the chair umpire, or an off-court official
- Whether coaching is allowed during breaks the Rules of Tennis do not cover — medical timeouts, toilet breaks, changes of attire, weather suspensions, wheelchair repairs
- What the penalties are for coaching outside the permitted times or manner
That penultimate point is the one that produces most on-court disputes. A medical timeout or a suspension for rain is not a break defined by the Rules of Tennis in the way a changeover is, so whether a coach may talk to a player during one is a tournament-level decision rather than a universal rule.
The long trial
The 2025 rule change ended a trial period that had run since 2017. The WTA moved first among the tours, permitting coaching during matches from 2020, having previously experimented with a version in which coaches physically came onto the court at changeovers. The ATP began trialing off-court coaching from designated seats in July 2022, running it through to that season’s Finals.
Its conditions were essentially those later written into Rule 30: designated seats, no interruption of play or hindrance of the opponent, verbal coaching only at the same end, hand signals at any time, short phrases rather than conversations, and no contact when a player leaves the court.
From 2023 the trials ran simultaneously across every major sanctioning body — all four Grand Slams, the ATP and WTA tours, the ITF World Tennis Tour and the ITF UNIQLO Wheelchair Tennis Tour — which gave the ITF a full professional season of comparable evidence before the vote.
Why the officials wanted it
The argument that carried the change was not primarily about players. The ITF Rules of Tennis Committee listed alignment across sanctioning bodies, player development and entertainment value among its reasons — but two of its stated grounds were about officiating: the old rule placed a policing burden on chair umpires, and enforcing it required subjective judgements.
That is a real problem. A prohibition on communication “of any kind and by any means” asks an official to decide whether a shrug was instruction. The ITF reported that chair umpires themselves welcomed the change, on the grounds that it let them concentrate on the match instead of on the player box. For how that fits into the wider division of authority, see our explainer on tennis officials and who decides what.
What is still not allowed
- Coaching during the playing of a point, anywhere, ever
- On-court coaching outside team events with a seated captain
- Coaching that interrupts play or hinders the opponent
- Verbal coaching from the opposite end of the court
- Extended conversations between points, as distinct from brief instruction
Penalties for breaching those conditions still run through the standard code of conduct, administered by the chair umpire under the same escalating structure that governs the shot clock and other time and conduct violations.
The net effect is that a practice the sport spent decades trying to stamp out is now, in most professional events, simply part of the furniture — visible, regulated, and considerably less interesting than the arguments it used to cause.
