It won't create any problem. The letter of consent should be only from your mother but she should state in the letter that the account is a joint account with your brother

Thanks a ton for your reply!

Hi guys! I need urgent advice. So I need to show £7380 for maintenance in my parents' account. The problem is that my mother has a joint account with my elder brother. Will this create problems? Do I need to provide letter of consent from both my mother and brother?

Thanks!
