My daughters father is threating to take custody of my daughter…but he is illegal. Can he still try to take custody of her?
Nobody can say yes or no to this question, every case is different but the fact that he’s illegal would probably not go in his favour, particularly if there was a threat he might remove a US citizen from US soil – American courts take a dim view of non-American parents removing their citizens from the country
Get yourself a really, really good (and preferably nasty) lawyer & let him/her frighten the sh*t out of your ex
I’m making a lot of judgements here but if you were a really bad, neglectful parent he wouldn’t tell you he was going for custody he’d just do it, what he said is the mark of a nasty, manipulative creep, who’s trying to control you even after the relationship is over – if this is the case build up your support network, make sure they know what’s going on & get a lawyer to ensure you follow every legality correctly
edit: don’t report him & get him deported, you want him right in front of you where you can see him & know what he’s up to
