10 v 10 Co-Ed Softball Rules

NJ Play Sports General Rules (All Programs) 



  • The scheduled start time of your game is when the clock will start. 
  • We allow a 10 minute grace period. This grace period is for teams still getting ready, teammates running late, etc. "(Please keep in mind that the game clock will be running during the grace period)"
  • After 10 minutes the game is officially ruled a forfeit. If the teams still want to play after the grace period is up, the referees and site managers will still run a game, but the game will still count as a forfeit for the standings.
  • If an official is late or doesn’t show up, teams have a choice to self-officiate, mutually agree upon an official (team member or spectator), or allow a Site Manager to officiate the game. Games will not be rescheduled and will count as an official game.
  • Games are rescheduled or refunded/credited in the event that NJ Play Sports specifically cancels a game. Reschedules and refund/credits do not apply in events outside of NJ Play Sports control (ie: excessive rainouts, forfeits, etc.) 
  • All subs must fill out a waiver in order to participate in games. At least 50% of the players on the team must be on the roster. You may have no more than 1 bench player available, if you are inviting subs/guest players to the game. 
  • Rosters: Each team can have as many players as they choose as long as they meet the league fee and gender specific qualifications. The roster deadline for every league is the night before the last regular season game. Once the last regular season game is played, no changes may be made to the schedule. 
  • *NJ Play Sports does reserve the right to make an exception for extreme cases, in order to avoid forfeits. 
  • Roster Checks: Roster checks will be conducted before the start of every game. Substitutes are allowed during the regular season.


If you know you may not be able to field a full team, please let us know at least 48 hours in advance and we will try our best to reschedule your game and avoid a forfeit:

Player Protests 

In the event that a team feels that the referee or site management does not acknowledge or incorrectly assumes a written rule in the NJ Play Rule Book the captain can protest said rule. The captain is protesting the fact that the rule exists or is different from what the referee is applying to the game. They are NOT protesting the interpretation of said rule or protesting any judgment calls on the field.

When a team protests a rule they must declare they are officially protesting the rule, the game will pause while the site manager and/or team captain confirm the rule exists or that the rule is being read correctly. If the rule exists or was being read incorrectly this is considered a successful protest (see below). If the rule does not exist or was being read and applied correctly on the field, this is considered a failed protest (see below).


Successful Protests:

Protest must take place on site before the next play begins, no alterations to the game can take place after the next play begins.

Play will continue using the accurate rule

Failed Protests:

Softball/Kickball: An out will be recorded at the teams next at bat
