How does one check to see of their minister is "licensed" to perform marriages?
Washington State does not "license" persons who are authorized to perform marriages.

It is the person within the religious affiliation who is recognized or granted the power (consequently, "licensed" by the religious affiliation) to officiate over wedding ceremonies.
