I'm annoyed when I read this thread. His mother did not get him into this mess as one posted said, his own speeding got him into this mess coupled with his inability to remember to pay a fine.
I am fed up of reading about people trying to find loopholes to get out of speeding fines. Every morning when I drive into Dublin I get almost ran off the road by lunatics driving at 20-40km over the speed limit, passing on solid white lines, not using indicators and loads of other things. I know the OP is only trying to help her BF and that is fair enough and good luck to her on that, but if you do the crime, you should pay the fine
Apologies for the rant, but as I said, this makes me mad
