不要隨便加意思，可以附加文件說明。

大多數人不是讓法官結婚，而是找神父。所以你的翻譯有點雷。

marriage license可以譯為 結婚許可證。

marriage certificate 結婚證書

結婚許可證在簽發一天後起效，有效期60天。

許可證失效期：whatever the date on the paper, don't invent new stuff.  

You can have some official include a government document explaining marriage license and marriage certificate in IL, and translate that too.
