Back in the 1990s in Chile, the law separating legitimate and illegitimate children was abolished and all children started to have the same rights. I'm not sure, but I think the term "illegimitate" was remove from the law altogether.
Of course, this wreaked havoc at first since many "hidden children" had rights to be visited and were allowed access to a range of rights overnight. Most official wives knew about the existence of those "children on the side" but preferred to ignore and shun them, and to keep them away from any rights. Well... it took a few months (maybe more), but finally all was normalized and accepted.
Now, I was surprised to learn that in many countries this difference still exists. Of course, this is only my ignorance speaking. I should have known better.
How can I find out in which countries does this difference still exist? Is there any map that clearly shows which ones implement it (and to what degree) and which ones do not?
