<h1>Legal checklist for month-long international riverside light festival: permits, safety, IP clearances, contracts, and refund policies</h1> An international light festival will run across public riverside and park venues for over a month, featuring nearly 60 large-scale installations and 100+ performances developed through collaborations with an internationally renowned director, foreign and domestic art teams, national art institutions, and multiple commercial partners. Legal points include required municipal permits for use of waterways and public parks, public safety and crowd-control obligations for outdoor and water-based performances, licensing and intellectual property clearances for imported shows and branded pop-culture elements, contractual risk allocation with vendors and artists, and consumer-facing liability and refund policies.
