Practice Areas

Lewis developed his advocacy skills in the criminal courts but since about 1995 he has practised exclusively in family law, and in particular in the sphere of “big money” financial remedies (financial provision following divorce) and ‘Schedule 1’ cases (financial provision for children of unmarried parents). He has appeared in many of the leading cases either as junior or, since 2002, as leading counsel.

Lewis has been a long-time member of the editorial board of the FLBA publication ‘At A Glance’ containing key information on all aspects of ancillary relief (and available in many good book shops and on e-reader), and a member of the team responsible for AAG Cloud © (formerly known as @eGlance ©). He is one of the founder authors of Financial Remedies Practice (now in its 10th edition).
