Joint Account

I am planning on filing bankruptcy in a few months and am only waiting because I had a change in income. I am on a joint account with my father. I don’t use the account, I don’t put money in the account, I don’t do anything with it. The balance is about $1500. This isn’t his main account or anything, he is doing all sorts of things with his accounts and trying to get everything set up for when he passes away eventually (not imminent, he’s in good health and in his 60s). Will this be a problem when I file? Should I try and get off the account now? I DO NOT want to talk to my dad about bankruptcy. We have a strained relationship at baseline and I don’t want to give him the ammo against me. Help?!
