In France it's possible without legal consequences (though immoral), if you call 119, you can push to have a baby taken from a family for no reason except that you do not like someone.

Claim that you suspect there may be abuse, it will trigger a case for a "worrying situation".

Then it's a procedural lottery:

-> If you get lucky, they will investigate, meet the people, and dismiss the case.

-> If you get unlucky, they will take the baby, and it's only then after a long investigation and a "family assistant" (that will check you every day), that you can recover your baby.

Typically, ex-wife who doesn't like the ex-husband, but it can be a neighbor etc.

One worker explains that they don't really have time to investigate when processing reports: https://www.youtube.com/watch?v=VG9y_-4kGQA and they have to act very fast, and by default, it is safer to remove from family.

The boss of such agency doesn't even take the time to answer to the journalists there...

-> Example of such case (this man is innocent): https://www.lefigaro.fr/faits-divers/var-un-homme-se-mobilis...

but I can't blame them either, it's not easy to make the right calls.
