Charlotte advises on all areas of family law. She advises on financial remedy cases and has particular experience in complex and high value cases, often involving trusts, business interests, offshore assets and/or cases with an international flavour. As parties increasingly sign up to pre-marital agreements and as they are being given more weight by the courts, she is finding herself more frequently advising in cases involving a challenge to the validity of the pre-marital agreement on a subsequent divorce.

Charlotte also advises on all aspects of private children law including contact, residence and leave to remove applications.

She advises on the drafting of pre- and post-nuptial agreements, and has done so in many cases involving very significant assets and income.  She also advises on issues which can arise between non-married couples, including cohabitation agreements, financial claims for children under Schedule 1 of the Children Act and TLATA claims. Charlotte has written numerous articles for the industry and popular press, including New Law Journal, Spears Wealth and The Times amongst others.

Charlotte is admitted to practise in England and Wales.
