@clacke Yep, as Indonesian, living in Indonesia, single never married, not have a legal background, and have religion, I also just learn about this too, tbh 😅
I read your question, browsing some resources a little bit, as most resources are indeed in Indonesian, and I try to understanding from what I read, so I might be wrong or biased at some point 😅
But hopefully (from me), the overview about this topic that I just talk about it, its still relevant with the factual condition.
