Depends on what you need the document for. In many cases, foreigners are required to provide a document from their home country that has been legally translated and apostilled. As the DR is a signatory of this convention, they apparently expect all countries to comply. Here's more info on the what and why Apostille Convention - Wikipedia, the free encyclopedia .
Ok, I know about the legally translated documents, but what happens if you're asked to get the apostille legally translated as well? I thought that this was not necessary.
You normally have to get the document apostilled before it is translated and in my experience the translators in this country I have used translate the apostille as well.
