'Inheritance Disputes and their Resolution', with Dr Maria Federica Moscati.

This research project has received ethical approval from the Research Ethics Committee at the University of Sussex. The purpose of the study is to understand the sources of inheritance disputes and how they are resolved, and whether mediators consider them as family or commercial disputes, and how they decide which style and models to adopt for their resolution.

Sibling dispute (2022): ‘You’ve provided a great service and been such a help to us. With heartfelt thanks.’

SEND dispute (2022): ‘Amazing. Helped me understand the process we were going through. Had patience with me and everyone involved. I don’t know what I would have done without his help. I recommend him in case you need mediation.’

Family inheritance dispute (2021): ‘We thought you handled the case superbly from start to finish. The result speaks for itself. We are most grateful.'

Workplace dispute: 'I just wanted to reiterate how grateful I am for the professional but caring approach you have had to this difficult process. I am very grateful to have had you recommended to me.'


Andrew has been described as a constructive and pragmatic mediator.

His style can best be described as engaging and approachable, yet tenacious.

He is highly skilled in creating the right atmosphere for openness and creative thinking.


Andrew's fundamental belief is that if most people are given the opportunity to work together, think creatively and problem solve in a safe and structured setting, then with the help of a skilled mediator, most things can be sorted out.
