any NJ lawyer? please chime in, I can't afford an attorney on this.

Spouse filed a post-divorce motion (divorce was 12 years ago) to emancipate 2 children who are now in college. As an exhibit to the motion, he attached a series of text messages between he and each child. These texts contained some personal information about each child that I don't think they would want made public. #1 is he allowed to do this? #2 does it become public record? Can someone request copies of these filings and also get that information? Thank you in advance for your response.
