I'd think so, but you'd be better off asking a solicitor after giving him/her all the facts
They can't "win" back the custody, that's up to Child Welfare. However, it would help for you to be represented by consule to guid you. Get someone who specializes in child welfare.
Whats the reason? They are an impartial judge that go by things like a place too live, job, not on drugs, support group, child in danger... list is endless
I am just showing possible reasons on why a child can be taken. Peoples actions can dramatically affect those ideals :)
its usually drug addicts/alchoholics,have their kids removed,for obvious reasons,and they usually get them back ,im neither,they kidnapped my daughter for no reason,kept her a year,and refuse to let her go for fear i will sue/claim compensation.without her,i cant do a thing.its cost taxpayers thousands of pounds,its a disgrace.the judges magistrates and all in family court lie and stick together,they have no interest in children,or the truth,they all know their part,to play,to stitch up innocent parents,there are no policeofficers in court,if you walk out nobody will stop you,its just a pantomime,its a disgrace
