About

Charlotte advises on all areas of family law. She focuses on financial remedy cases and has particular experience in complex and high value cases, involving a combination of trusts, business interests, offshore assets and often with international elements. She regularly advises on the drafting of pre-marital agreements, including in high and ultra-high net worth matters, as well as litigating to enforce/challenge pre-marital agreements upon a subsequent divorce. Charlotte also advises on all aspects of private children law including contact, residence and leave to remove applications.

Charlotte is committed to minimising the collateral damage of divorce on the family. She tailors her approach to all cases carefully to ensure clients’ interests are robustly protected whilst also minimising unnecessary conflict.

Charlotte splits her time between her case work and a knowledge role, supporting the family team both internally and externally.  She writes and provides commentary regularly for the legal and popular press including Family Law Lournal, New Law Journal, Spears Wealth, The Times and Financial Times amongst others.

Charlotte is admitted to practise in England and Wales.

Experience

  • Assisted with a complex, international financial remedy case, acting for one of the spouses in a case involving a family business and assets worth several billion dollars. The case involved several parties and complex international trust arguments and was ultimately settled confidentially part way through a three-week High Court trial.

  • In a case concerning a family living between several different countries with very significant assets in complex tax planning structures across several different jurisdictions, Charlotte finalised a post-nuptial settlement from first draft to signed agreement in the space of a week

  • In a hard fought case, involving substantial pre-acquired assets protected by a pre-marital agreement, Charlotte successfully defended a challenge to the validity of the pre-marital agreement. She subsequently advised on implementation of the agreement, navigating significant disputes about value/tax treatment of most of the assets

  • Acted for Lady Judge in her application to the Court of Appeal to set aside judgment in her financial application on the basis of mistake, non-disclosure and supervening event

  • Advised in cases with domestic abuse including appropriate contact and residence arrangements for the children in the context of the abuse and financial proceedings
