Answer
Through the Russian Consulate in Uruguay, you can request civil registry documents through the available document-request service. The document is issued in Russia and then sent to Uruguay through diplomatic or postal channels.
The estimated time frame for obtaining documents this way is 2–4 months. This route is convenient if there is no representative in Russia, but it is not always suitable for urgent filing because the wait depends on the request route and document delivery.
An important limitation: the Russian Consulate in Montevideo allows you to obtain certain documents, but does not apostille them. Therefore, it is necessary to understand in advance what form the document will arrive in, where it can be apostilled and how to prepare the translation for the Uruguayan recipient without losing time.
