adam is right...a muslim wedding, one will get after the 'ceremonie' that bluebook...like an ownersbook, hahaha..but no worries they issue two, one for the wife owning the husband and vice versa..this book will in a case of divorce or death be sufficient for the courts..in other words...a muslim marriage is right of the bat a 'legalised' marriage.
a Hindu wedding for it to be a legal wedding needs to be registered, after the wedding (duh) at the catatan sipil with all the other documents as descibed in previous posts.
converting to Hindu, is as easy as 1,2,3 or A,B,C.
same goes protestant...you'll get baptist (sprinkled with water) get an certificate of baptism and that's it, easy right? for it to be legally recognized...again of to the catatan sipil to register it.
catholic is a bit different...maybe depending on the church (???), but since they all 'report' to the vatican about income/expenses/marriages/deaths/etcetc...) it's a bit more strict and one
needs to take classes with the priest/referent/dominee (no idea which his name is) and at the end ofcourse an examination. In this period (6 months) attend church-services, and be actively
involved...whatever that means? Anyways after all that then still one needs to go an register this at the catatan sipil.
haven't met any buddhist here, nor did I search for info about the ins and outs about their ways, when I wanted to get married.
bottomline for people (mixed-marriage) who would like to apply for an spousevisa/kitas, no other way then to just marry under the Indonesian rules.
one could get married abroad ofcourse and it would be totally legal there, but overhere you could not apply for that visa unless of the same religion and either have the blue book or the
weddingcertificates from the catatan sipil.
Not to mention how happy one would make inlaws, by marrying their daughter/son overhere...
