After obtaining her LLB, Petrova went on to complete a Masters in Law at University College London before undertaking her Legal Practice Course. She qualified as a Solicitor in 2007 and on qualification was approached to join a leading Thames Valley firm where she remained for five years, this was followed by a period of time with an award winning London firm. After a brief spell out of law enabling her to diversify her knowledge, skill set and gain valuable experience in other areas of industry, as well as developing her transferrable skills she was delighted to return to family law in 2016 as part of the Family Department at Lightfoots. She has built up considerable experience advising and assisting people following the breakdown of a relationship, whether this be to deal with divorce, finances or children. She advises in all areas of family law, including in preparation for marriage, and is praised by former clients for her “excellent” advice, allowing them to feel confident in their rights and responsibilities and that their “case has been very safe in [her] hands”. In 2018 she qualified as a Mediator, providing her with further skills to assist those instructed by her. Petrova became a Partner in 2021.

As a member of Resolution she is committed to adopting a non-confrontational approach, and this is confirmed by client feedback “ I needed a constructive, non-confrontational, but firm approach – which she was”. She is ranked by leading legal directories Chambers and Partners and Legal 500.
