I don't think it has anything to do with your son,
It more than likely is an attempt to have his own juvenile history sealed.
If this is something that involved your son you only need to produce proof your his mom,
( A birth certificate would do)
And then legally request copies of the records.
which you as his mom would be entitled to.
Statue - means Decree-
IN this case it means to legally determine.
And SEALED means-- to close
So he wants to Legally close.
OR make thse records unavailable.
Statutorily eradicated generally means erased by statute. For example, a statute may provide that records of juvenile offenses are removed from official records when the juvenile becomes an adult and certain conditions are met. It is a process that occurs automatically by statute, as distinguished from records of offenses which are expunged or sealed upon request by an individual.
