Children cannot inherit until they reach the age of 18; below this age, the funds are held in Trust. If you think 18 is too young for your children to inherit a large sum of money, within a Will you can specify that they do not receive the capital sum until a later age. They will, however, be entitled to receive any income from the trust fund as soon as they reach 18. Apart from this, the Trustees decide what income and/or capital can be used for the benefit of the children e.g. school fees.
