You are going to have to jump through a lot of hoops. First you have to have the court's permission to take you son out of the country (Illinois law) and your ex will be allowed input. Your visitation plan can be altered if need be but the biggest factor is your son. If he's old enough to tell the judge why he wants to go to school in Spain, the judge may circumvent the system and allow it. There is also the option of allowing your son to spend summers with your ex and the rest of the time with you. You're going to have to sit down and hash it out between the two of you before going into court and come up with a game plan. Remember the judge is only looking out for the child not the parents.
