COSASL values and appreciates every Manager for the time and effort they put in to making each season a success. Please review the directions to ensure you register your team correctly. If you have any questions please fill out our Contact Form




Managers complete the team registration process before the Fall and Spring seasons.

This is a two-step process that involves registering your team with our league and also with the Colorado Amateur Soccer Association (CASA). CASA is a statewide association that partners with many adult leagues providing insurance and administrative support.

To begin:

Step 1: Register your team with CASA

Go to the CASA site at and register your team. The fee for each season is $100.

Ensure you select our league, COSASL, and then select your division. Once this is complete, you are ready for Step 2: Registering with COSASL.

Step 1: Register with CASA

Step 2: Register your team with COSASL

On the COSASL website click on the Managers tab and then select “Team Registration”. You’ll notice that COSASL is supported by Sports Connect to assist with many administrative functions of the league to include collecting fees. Registration for each season is $1700 per team. A $200 deposit is required to reserve your place and the balance will be due before playing the second game of the season.

Step 2: Register with COSASL

Reminder!!  Player cards are good for one year starting with the Fall season and carrying over to the Spring season.  A new player joining for the Spring season would be required to purchase a player card, and would then need to buy a new player card in the Fall.
