The reason why marriage records like Gwinnet County Marriage Records are some of the most requested for records from the government lies in the fact that these are the official records of the government in regards to the fact of the marriage and because that is the case, these records are the best evidence that one could present in order to prove the fact of the marriage. The next question would be why is it necessary to prove the fact of the marriage, and the reason for that would be because marriage is something that would alter the status of the person who had gotten married and such alteration would follow the person no matter where said person may go.
The fact that such change of status would follow the person means that the limitations imposed by the fact of the marriage as well as the rights that are imposed by the marriage would follow the person no matter where the person in question may go. Thus, a person could not escape the fact of his marriage and get married to another person by simply going to a different jurisdiction, but at the same time, his spouse could not limit the rights of succession of said person by simply going to a different jurisdiction as well.
It is for the limitations and rights that are imposed by the marriage that marriage records are being requested for and these are the best evidence to present because, as the official records of the government, these records are given the presumption of regularity such that the contents of the records are presumed to be true and accurate at all times. The presumption, however, attaches only if the records in question were obtained from the proper sources, thus, while there is no need for the party presenting the records to prove that the contents are true and accurate, he or she would still have to prove that the records being presented were obtained from the proper sources.
Most requests for copies of the records are coursed at the local level as there are fewer records that would have to be checked here and there is also the fact that local level offices are always easier to go to. Of course, a request at the local level would be rather limited because the offices at this level would only keep copies of records for marriages that were celebrated locally. Thus, if the marriage was not celebrated within the jurisdiction of the office where the request would be made, more often than not, there would be no records of the marriage in question. The method for making the request at this level would depend on the office where the request would be made, though it would usually be through the mail or in person.
Gwinnet County Marriage License Records may also be requested for and obtained online through the use of online databases, though note that most of these databases are not officials sources, hence, despite the fact that they could present information that would be roughly the same as that which could be found from the official sources, any and all information obtained from them could not be used for official purposes.
