What aspect of an agent's behavior can increase the likelihood of personal liability?

The aspect of an agent's behavior that can increase the likelihood of personal liability is committing serious violations such as fraud. This is because engaging in fraudulent activities involves deceitful practices that can harm clients, clubs, or the integrity of the sport. Such actions not only breach contractual agreements but also violate legal statutes and football regulations. As a result, an agent involved in fraud is likely to face claims and litigation from affected parties, leading to personal liability for any resulting damages.

While having a good reputation, participating in continued education, and maintaining positive client relationships are all positive behaviors that can help an agent build trust and credibility in the industry, they do not directly increase liability. In contrast, serious violations like fraud create significant legal ramifications, which is why they notably enhance the risk of personal liability for an agent.
