A more thorough explanation:

A frivolous claim is a legal claim that has no legal basis or merit, especially one brought for an unreasonable purpose such as harassment. It is a claim that is not supported by any evidence or law and is brought solely to waste time or cause trouble for the other party.

For example, if someone sues their neighbor for $1 million because their dog barked too loudly, that would be considered a frivolous claim. Another example would be if someone files a lawsuit against a company for a product they never purchased or used.

Frivolous claims can be dismissed by a judge, and the person who brought the claim may be required to pay the other party's legal fees. This is to discourage people from making baseless claims and wasting the court's time and resources.
