This is one of those things that drives me crazy. My husband works at a bank. He's a credit officer for goodness' sake, but he is horrible with paying the bills. We didn't have a joint account for a long time, and I still don't pay all of the bills. The mortgage and utility bills are his task, but there are times I'd really like to take it away from him because he doesn't pay them. I pay bills as soon as I get them, or like for the beach house mortgage, I always pay it on the 25th (early). I don't budget or spend time going over my bank statements. I have the general idea and look close enough to make sure weird charges aren't there, but that is about it. We have some bills set up as auto pay, but he piddles around with the rest and it drives me crazy. Our main mortgage is ridiculous because the only way to pay online is to incur a $15 service fee... which he does every month because he's usually paying it at the last minute. Grrrr.
Right before we got married, he'd refinanced the house and had new windows installed. The bank gave him a $10,000 check from a line of credit they started for him. He never cashed the check. He actually lost/recycled it. AND HE WAS PAYING THE BILL EVERY MONTH even though he never cashed the check. I bugged him about it for YEARS. I couldn't do anything because my name wasn't on the mortgage, so they wouldn't talk to me. The mortgage company bugged him about it at one point,but he never followed through with them. Then they sold our mortgage to another company, and then that company resold it, so finally someone caught on to the fact that he'd never cashed that check. He'd paid about $6000 of it (including paying interest... on money he never had), so he got a refund finally... but STILL!!! How can you work in finance every day and not do something so simple? I love to tease him about that. It is just insane.
