You may ask the Solicitor for a copy of your late father's Will to be given to you, if you are not given the copy, you may search the Probate Registry as the Will becomes a public document once Probate is granted and anyone can look at it.
You may challenge the Will within 6 months of grant of probate under the Inheritance (Provision for Family and Dependents) Act but there is no moral right to leave anything for children, so if you feel you have not been provided for adequately in the Will, I am afraid you will have a difficult time challenging it unless there is a good reason for you to do so.
e.g. if you were financially dependent on your father or if you were disabled. It will be difficult for you to challenge the Will on the basis that you were abused by him especially as this was not reported to the Police.
