I am really sorry to hear all of this.
Unfortunately, the person who is going to be liable for these funds is your mother.
She is not the person who should be going to court as she is the person who had these funds invested or lock up in some way for you and if they are gone she is liable.
The court documents would not be sealed and if for some odd reason they were you would be told this.
So if you cannot find a court file then one didn't exist.
The court clerk at the court house office should be doing a search of the archives for you.
As well, you can contact the OCL and see if there is a file there. If there is any judgment on behalf of a minor they would be told if things were done lawfully.
Here is a link to the contact information you will need:
The school would also have records and you can do a Freedom of Information Request though those documents may be gone now.
The court keeps all records.
If none of this works you can bring an application to the court but this will be very complex and may involve suing your mother unfortunately so you should have your own lawyer represent you if you need to go that far.
