You might have to revamp this a whole lot. It's going to depend upon how accurate you want it to be.
Here's a classic scenario that designed to baffle the crap out of people. Fifteen-year-old kid, with a clean record, is convicted of DUI and stolen car. As a juvenile, he's entitled to his record being sealed. Right?
Wrong. Sort of. His car theft will be sealed as a juvenile record. Nothing will appear about that. His DUI on the other hand, will be placed upon his motor vehicle record. And this is a permanent record. If he stays clean for fifty years, he still can't get it removed.
Further, the information will be released by the motor vehicle department in accordance with normal policy. If it is normally supplied to newspapers, his name will be too. It can be published by the newspapers. His age will not effect the distribution of his name one bit.
Further, at the time of his arrest, the police can release news that he's drunk. Let's say he trashes the car in a newsworthy fashion. The police can announce his name to the public and the fact he's drunker than a skunk. What the police will refuse to comment on is how he got the car, i.e., stealing it.
Driving offenses always appear on your driving records, and driving records are quasi-public documents. Employers have a right to request them and rely on them as being accurate. Newspapers can request them for stories (five time convicted drunk wrecks again!). Auto insurance companies use them to set rates.
In addition, a DUI nearly always requires a suspended driver's license. In the case of the fifteen-year-old, a judge would probably suspend his license for two or three years, making it impossible for him to legitimately get a license until he is seventeen or eighteen, instead of the more normal sixteen. Again, this information has to be available to the police and public.
So the only way dad could seal junior's record is going to be very expensive. He would have to bribe the judge, the clerk of the court, the police officer, probably people at motor vehicle, and I'm not sure there wouldn't be others. And the seal would last until a clerk at court looked at the record. Definitely only the original judge, probably only with additional funds from dad, would keep it sealed. And the investigation that would happen would be serious.
Best of luck,
