Mark Devlin told the BBC: "The club at the time obviously didn't have the money to pay it in one big hit, so they began to pay it on a monthly basis.
"There was a reassessment of where the money needed to go, and we haven't paid Andy for two or three months now.
"He decided to take us to court which is totally understandable, it's his prerogative.
"We do fully intend to pay Andy but we need to pay him when obviously the club has the money."
