1. The simple method of avoiding costly disputes in relation to a will is to set out a clause in it that provides that all disputes arising shall not be dealt with by court proceedings but shall be determined by mediation before an appointed mediator whose decision shall be final and binding on all parties to the will. You can appoint a person you know as mediator and in default have someone nominated by a professional body such as the Law society or the Bar Council. YOu can also specify that anyone who does abide by the mediator's jurisdiction shall forfeit any claim under the will or upon intestacy. In this way you can avoid costly recourse to lawyers and have a simplified dispute resolution mechanism which means that all of your estate goes to your beneficiaries and does not get dissipated upon legal disputes, thereby benefitting no one but the lawyers.
