After our wedding my husband and I went our separate directions due to our work and he took all the checks/cash to deposit. There is one check that won't deposit for some reason. It is a cashier's check, but our online banking system won't accept it. We thought we could hold on to it until Christmas when we would be together and I could try with my check deposit aps, but to no avail. It is now 3 months after our wedding and we have a cashier's check we can't cash...any ideas on what to do?
