There is a World Bowls Organisation which does what it says, oversees the game World Wide.
Each country which plays the sport, has it’s own governing body, from there it cascades down through regions.
From Valencia down to specific areas like the Costa Blanca and within that, you have Bonalba who are covered by the Levante Lawn Bowls committee, known locally as the LLB.
The LBB consists of all bowls clubs within this area and each member club has a seat on the committee, meaning the clubs are virtually self-governing within that framework.
