Family issues require a particular set of skills and sensitivity to help clients see clearly the choices they face and to understand both what is possible and what is desirable.

With our partner-led service we can advise on all aspects of family law, whether parties are married or cohabiting. This will include the financial implications, procedures to be followed during a separation or divorce and arrangements for the family’s children.

The right tactical advice can be crucial, particularly when dealing with claims of a significant value, or claims with an international element. The need to move quickly can be imperative when determining the jurisdiction in which a divorce and financial claim should be brought. We are also able, if necessary, to protect the family assets from dissipation by swift reference to the court.

Our approach, while always alert to the sensitivities of family relationships, is pragmatic and commercial and we are not afraid to give clear guidance and advice and to protect our client’s interests through court proceedings where necessary.

Issues relating to children are particularly sensitive and they increasingly have an international dimension. We work with clients to secure the best outcome, for the children and for the client. Beyond conventional family matters we also offer advice on:

  • Mediation, both on financial matters and issues relating to children
  • Collaborative law
  • Access to independent family arbitrators

In addition to advising on relationship breakdowns, our team provides advice on forward planning asset protection, including pre and post-nuptial agreements. We are supported by lawyers in other specialist areas who advise on issues including:

  • Private capital – asset management and protection, tax planning and trusts, and international private capital
  • Employment
  • Corporate, particularly with regard to family companies
  • Real estate
  • Tax

Examples of the work we undertake include:

  • Divorce
  • Financial claims on divorce
  • Children’s issues (domestic/international)
  • Separation agreements
  • Cohabitants’ claims
  • Civil partnerships
  • Pre- and post- nuptial agreements
  • Cross-border disputes (forum shopping)
  • Mediation – all issues
  • Collaborative law

Clients range from entrepreneurs, HNW individuals, accountants, medical professionals, investment bankers and financiers, beneficiaries of both offshore and onshore trusts, high profile actors and sportspeople, authors and designers.
