My friend is having trouble getting his inheritance from his Family Trust because of an issue with the literal name of the trust fund.... help

My friend John Madigan is having problems getting the money from his family trust. His mother passed away a couple years ago, and he and brother and sister still haven't collected yet. As I understand it, the paperwork that John has says something like "Madigan Family Trust," but the bank has it labeled as the "John and Mary (or two names) Madigan Family Trust. The bank is being difficult and they're saying they won't pay them because of the name difference.
