I know he's nut, that's why i applied for my 2 boys by self and i save consultancy fee. But I'm just curious if i can still declare him because when i apply for my 2 children there is declaration form for my children and i just declare my 2 children and i neglect 3rd one because i don't have his custody yet, that's why I'm thinking i did a big mistake even my wife aware everything and she's my cosigner and atleast we just want to declare him but we were in hurry .
