Maria Coster

Partner | Family & Matrimonial

Maria has worked exclusively in family law since 2012, having previously worked at two specialist family law firms before joining Ward Hadaway.

Her approach is best described as firm and pragmatic, yet empathetic when required. She adopts a strategic mindset in every case, often playing devil’s advocate to anticipate opposing arguments and advising clients on how best to overcome any foreseeable hurdles.

Maria is frequently praised by clients for her efficiency, dedication, and commitment to achieving the best possible outcomes. She prides herself on her attention to detail, her concise and clear advice, and her unwavering focus on client care. Many of her clients go on to recommend her to friends and family, often commenting on her tenacity, compassion, and professionalism.

Maria advises on asset protection during relationships, including pre‑ and post‑nuptial agreements and cohabitation agreements. These documents help clients achieve financial certainty and can prevent contentious and costly litigation in the event of a future separation.

Following separation, Maria advises on the dissolution of civil partnerships, divorce for married couples, and separation arrangements for cohabiting couples. She regularly assists clients with substantial assets, business interests, international elements, disputes involving spousal maintenance, and applications to vary existing financial court orders.

In children matters, Maria has acted in complex cases involving significant parental conflict, domestic abuse, substance misuse, and cases where a Guardian has been appointed to represent the child’s interests. She has also represented clients in cases involving proposed removal of a child from England and in proceedings requiring the court to determine jurisdictional issues.

Maria was recognised as a Rising Star by the Legal 500 in 2020 and 2021, and as a Next Generation Partner from 2022 to 2024 (inclusive).

The Legal 500 recommends Maria as “an individual who is extremely proficient in identifying her client’s main concerns” and notes that she “is always easily accessible and gives a measured and insightful opinion. Her expertise cannot be praised enough and she is highly recommended”.
