How is the first serve determined in a deciding set?

In volleyball, the first serve in a deciding set, which is often the fifth set in matches played to a best-of-five decision, is determined by a coin toss. This practice helps ensure a fair and impartial start to the final set, as neither team has a predetermined advantage or preference regarding the serve. The coin toss is typically conducted before the match begins and decides who will serve first in the deciding set.

The visiting team does not inherently have the right to determine the serve, and mutual agreement between head coaches is not an official regulation in this aspect. Similarly, while the second referee plays a vital role in the match, the authority to determine the first serve lies with the coin toss, not with the officiating team. This standardized process is outlined in official volleyball rules to promote fairness and consistency across matches.
