Straight foot locks will become illegal for adult and master white belts under IBJJF rule changes taking effect January 1, 2027. The same restriction will apply to every belt rank in the juvenile divisions for athletes aged 16 and 17.
The federation announced the package on November 13 and published a detailed comparison of the existing wording and the 2027 provisions. The changes cover submissions, scoring, penalties, uniforms and age divisions.
For adult through Master 8 blue and purple belts, the update permits turning toward the foot that is not being attacked during a straight foot lock. Athletes in divisions where the submission is prohibited remain barred from applying it.
White belts will also face a stronger penalty for jumping into closed guard on a standing opponent. That action becomes a severe foul carrying immediate disqualification. Coaches preparing beginners for competition will need to account for both the submission restriction and the revised penalty.
A new Master 8 division will accommodate competitors aged 66 and older, with four-minute matches. Master 7 will cover ages 61 through 65.
Other changes address double guard pulls, lapel or belt control with a wrapped leg, disciplinary disqualification and no-gi clothing. The federation’s full comparison includes explanatory videos and before-and-after wording.
For academies planning next season, the announcement provides a concrete reason to review competition drills and rules briefings by age and belt. The exact wording matters when preparing athletes who compete across different organizations.
