 As the same registrar also records marriages, for the convenience sake it is often done during the marriage proceedings, as governed by the Federal Law #143-FZ "On Civil State Acts", and the couple's marriage certificate has an option of having one common family name, or both spouses going by their original surname.However, the law is entirely gender neutral, and the couple may adopt either of their surnames (a husband adopting his wife's family name is an uncommon but by no means unheard-of practice, which is generally accepted and carries little to no social stigma), or even a completely different one.The law also recognizes the couple's right to use the combined family name, and for the either of the spouses to reclaim their original surname in the case the marriage is dissolved.
