Does a person pay fees other than taxes, for money returned on an investment deal cancellation in Malaysia?

I have a friend whose father was a contractor. He had a deal pending some years ago, but due to his death, the deal fell through. Recently, her father's attorney contacted her saying that the company housing the funds would be returning them. There was a large fee charged in order to release funds. I questioned this because if you are being returned funds, the only thing you would have to pay is taxes to your government in the country of residency. I am concerned because I don't want her to be taken advantage of due to the emotional state she is in. I am not familiar with Malaysian financial law but if anyone here is, please help.
