Capital gains tax on bond?

I would very much appreciate some advice. My mother divided her estate between myself and my daughters. Some investment remains in a property and a bond but I invested some cash into a bond for my daughters which was held in Trust as they were very young at the time. I decided to allow my eldest daughter (now 19) to cash in her bond in order to pay for educational training which otherwise would have meant she needed to take out a loan with expensive interest rates. Now that she has cashed in it I am assuming she needs to pay capital gains tax on the profit that the bond made. I am confused by the whole Trust thing. I complete a Trust tax return each year as my daughters receive an a small income form the property which is rented out. Presumably she will also have to complete a self-assessment tax return as well as she has also received interest above the £1000 threshold on this money whilst waiting to make the next instalment in her training.

Hi Kim Mynard,
You would need to check this with the trust office on 0300 123 1072.
Thank you.
