Emancipation generally means the child is self-reliant and can support herself through work. Because the government is going to begin taking over does not automatically mean you are no longer responsible for supporting your daughter. Your matter is complex and I recommend sitting down with an experienced family lawyer.

You need to look at your property settlement agreement under the emancipation section. Usually if your daughter got married or is not continuing her education you could seek to emancipate her. New Jersey is in a minority of the states where a certain age does not automatically emancipate the child. However, if she is planning on taking any maternity leave from her schooling you may seek to emancipate her, but she may be unemancipated down the line if she goes back to school.
