She has a lot of experience in cases regarding forfeiture and what constitutes a forfeiting event. Antonia acts in cases involving allegations of nuisance, trespass and boundary disputes as well as claims for adverse possession. She is equally happy in the County Court and High Court (including the TCC) as the First Tier Tribunal (Property Chamber).

She appreciates the value of mediation in such cases, but is very happy to represent clients in court if mediation is unsuccessful. Antonia will also advise on enforcement proceedings where necessary.

Antonia acts for businesses and has been instructed in numerous commercial disputes including breach of contract, professional negligence, misrepresentation and Consumer Credit Act claims. She has experience of cases where individuals are seeking to argue that their relationships with credit companies are unfair, often in defence to possession claims. She  frequently represents clients in applications for injunctions and damages. She is pragmatic in her advice, and will consider the commercial and reputational risks of litigation as well as the strict legal position.

Antonia is regularly instructed in company law proceedings involving Companies Act and Insolvency Act applications. She represents directors, former directors, companies and liquidators.

Antonia’s insolvency work includes successfully setting aside statutory demands, defending bankruptcy petitions, applications to annul, vesting order applications and resisting the presentation of winding up petitions.

Antonia represents Claimants and Defendants and is experienced in drafting pleadings and providing representation in the High Court and County Court. Recently, Antonia has been involved in a negligence claim against an architect, construction company and building control surveyor in relation to the development of a new-build property worth over £1 million.
