Kroy Biermann Jr. seems to be trying a new legal strategy after being indicted on seven felony charges in Georgia … because it looks like he’s trying to get his sexual battery case moved to juvenile court.

The eldest son of Kim Zolciak and Kroy Biermann had his attorneys file a motion to transfer the case to juvenile court for confidentiality proceedings … TMZ has confirmed.

In other words, the 15-year-old wants legal proceedings to play out in juvenile court, away from the public eye. Page Six was first to report the filing.

A court date has been set for Friday … so it will be interesting to see if the motion is granted.

As we first told you … Kroy Jr. was arrested last month after a classmate accused him of sexually assaulting her in a gym changing area. She alleges he forced her mouth on his penis and digitally penetrated her vagina — allegations he denies.

Kim has vehemently denied the allegations and has visited KJ behind bars several times as he sits in a Georgia jail.

KJ was indicted by a grand jury last week on 7 charges … aggravated child molestation, aggravated sodomy, aggravated sexual battery, three counts of aggravated sexual battery against a child under 16, and false imprisonment.
