- Cases involving controlling and coercive behaviour towards a former spouse or partner and strategizing to minimise the impact. Peter has advised both those responding to allegations and those making them.

- International relocations abroad with children – recent destinations include various US jurisdictions, Spain and Hong Kong.

Peter's clients have described him as "simply excellent", "extremely well informed, willing to put the time in to discuss matters at length" and "realistic about the options but showed a real flair". A former client of Peter's stated, "I owe Peter a huge life-debt: he literally came up with the formula which has enabled me to see my children in the intervening years". Another quoted "I quickly came to trust Peter’s strategic thinking and had complete confidence in his guidance. Whilst firmly at my side he always made me feel that the process was in my hands and could proceed at my pace where possible."
