Utah Declaratory judgment

[T]he conditions which must exist before a declaratory judgment action can be maintained are:

1. a justiciable controversy;
2. the interests of the parties must be adverse;
3. the party seeking such relief must have a legally protected interest in the controversy; and
4. the issues between the parties involved must be ripe for judicial determination.
