You can go abroad with your child.
But you can not alienate your child till he /she attains majority (Male 16 years. Female 18 yesrs ) from you either by adoption or by any other means without consent of your husband that is father of the child.
Valid alienation is giving in adoption only.
Valid adoption requires consent of both father and mother.
You will run a high risk of committing parental kidnapping of the child for alienation of the child without a valid adoption.
Now if you think obtaining consent of your husband is not possible for any valid reason you must obtain court permission for giving in adoption.
Be careful. Such matter should not be taken lightly because in such cases your husband may label the charges of kidnapping if his consent is not taken and no permission is obtained from court to this effect.
