For emancipation to happen the court will have to take into consideration on why your son should be emancipated.
§ 7B-3504. Considerations for emancipation.
In determining the best interests of the petitioner and the need for emancipation, the court shall review the following considerations:
(1) The parental need for the earnings of the petitioner;
(2) The petitioner's ability to function as an adult;
(3) The petitioner's need to contract as an adult or to marry;
(4) The employment status of the petitioner and the stability of the petitioner's living arrangements;
(5) The extent of family discord which may threaten reconciliation of the petitioner with the petitioner's family;
(6) The petitioner's rejection of parental supervision or support; and
(7) The quality of parental supervision or support.
§ 7B-3505. Final decree of emancipation.
After reviewing the considerations for emancipation, the court may enter a decree of emancipation if the court determines:
(1) That all parties are properly before the court or were duly served and failed to appear and that time for filing an answer has expired;
(2) That the petitioner has shown a proper and lawful plan for adequately providing for the petitioner's needs and living expenses;
(3) That the petitioner is knowingly seeking emancipation and fully understands the ramifications of the act; and
(4) That emancipation is in the best interests of the petitioner.
The decree shall set out the court's findings.
If the court determines that the criteria in subdivisions (1) through (4) are not met, the court shall order the proceeding dismissed.
