William Rollin

Senior Associate





William’s practice covers all areas of family law, including cohabitation and prenuptial agreements, separation and postnuptial agreements, divorce and the dissolution of civil partnership, the financial remedies upon relationship breakdown, variation of maintenance and private law children matters such as residence and international relocation.

He is particularly interested in complex financial issues and arrangements in respect of pensions.

William is a member of Resolution and is committed to assisting his clients to resolve family disputes as constructively and cost effectively as possible.

Wherever appropriate William encourages and facilitates the use of mediation and other dispute resolution procedures, but he is also experienced in litigation in the Magistrates’ Courts, County Courts and in the High Court.

William advises clients throughout the South East and in London, including in matters with international dimensions. He speaks French and German and welcomes enquiries upon any aspect of family law.

William is admitted to practise in England and Wales.


  • Advising in respect of both financial proceedings and children matters
  • Recently advised an applicant wife in relation to achieving a fair settlement when the multi-million assets were complex and financial disclosure provided by the respondent was deliberately obstructive; this included devising a settlement strategy and drawing together a team comprising counsel and shadow experts which achieved the client’s aims of a fair, early settlement without lengthy proceedings, but was substantially more generous than the respondent's early proposals
  • Advised a father in complex and long-running children act proceedings involving issues of parental alienation and significant psychological disturbance in the respondent mother
  • Regularly advises serving and former service personnel and public sector employees in relation to pension sharing of public sector pensions; this includes supporting clients to positive outcomes with the assistance of specialist pension reports to facilitate early settlement in matters where the pension may be the family's main asset and cost-effective resolution of the matter is critical
