Which type of personal information sharing generally does not require an opt-out notice?

Sharing personal information to comply with legal requests does not typically require an opt-out notice because it is mandated by law. When a company receives a legal request, such as a subpoena or a court order, it is obligated to provide the requested information to law enforcement or other government entities as part of legal compliance. This type of sharing is governed by specific legal frameworks that prioritize law enforcement's ability to access information over individual privacy preferences.

In contrast, the other types of sharing mentioned generally involve a commercial aspect where the consumer's choice is relevant. For example, sharing for affiliate marketing, consumer credit histories, and sharing information with competing firms typically requires companies to notify consumers and often provide an avenue for them to opt-out, as these activities are not dictated by legal imperatives but by business practices and consumer privacy rights.
