The reason that the government keeps track of marriages is because of the fact that marriage is something that changes the status of a person. Usually, only a competent court could change the status of a person, but marriage is an exemption to that, though one must first note that marriage is actually something that could not happen without permission from the government, albeit it is a permission that seems to be always given. This permission is reflected in the fact that a couple needs a marriage license before they could get married, and after they are, they would have to get a marriage certificate. These marriage license and marriage certificates are two of the many documents that are attached to a file known as marriage records, such as Nevada County Marriage Records.
Marriage Records Nevada County, being some of the most important records in the custody of the government, is public records. They are supposed to be available to the public at all times, but because these records do represent the status not only of those who were parties to the marriage but their children, there exists the need to ensure that the authenticity of the same be preserved. It is for this reason that the general public could only get their hands on informational copies. These informational copies, while presenting the same evidence as certified copies, could only be used to provide information, unlike certified copies which could be used for official purposes.
