Parking Tickets - Help!

My husband has ADHD. We are having a problem with parking tickets. He been getting ticket almost every week or other weeks. He doesn't pay them and hide them. I remind him to pay them. First, I get angry for getting the ticket in the first place because of his careless. Then, I said okay you got the ticket and now you need to pay it. He still doesn't do that. By the time I keep reminding him... he gets another ticket. He doesn't work. I am the one end up paying all the tickets with fine.  I need help here. What am I suppose to do? As of right now... we have 2 outstanding tickets. Help!
