Descresionary Will Trust Tax implecations and Chargeable Gain

My mother has recently passed, and has trusts in the Isle of Man, she was paid income from these and I am under the impression that if I were to surrender the trusts I would pay tax on the Chargable gain at 45% is this correct ? It is very complicated, it also mentions Segments gain per single segment?
