In Korea same sex marriage isn’t legal. So in order for queer couples to be recognized as family and have rights for and with each other (like medical stuff ect. And to be legally recognized as eo guardians) they basically adopt each other as parent and kid or what not. It’s like a roundabout way of marriage since they can’t actually get married.
In Korea same sex marriage isn’t legal, to be able to gain the same martial rights the only way is to added to the same family register. Like if one got into a horrible accident if they weren’t in some way legally connected the other couldn’t make medical decisions. Same as if something tragic happened being on the register gives them the rights to proceed with whatever legal procedures they may have to

Can someone explain the certificate to me please and thank you im confused
