Antonia Barker
Partner
Overview & Experience
Prior to joining Hamblin Family Law as a Partner in 2024, Antonia was a Partner at one of London’s leading family law firms, where she worked closely with Georgina for almost ten years.
She is once again individually ranked as a ‘Next Generation Partner” in the 2026 Legal 500 directory and is described as “switched on” and a “brilliant mind, brilliant lawyer and on top of that, a brilliant person.
Antonia advises on all aspects of divorce and financial remedies, including financial provision after foreign divorces, and for unmarried parents. She has acted for a variety of high and ultra-high net worth clients to resolve the financial issues arising from their relationship breakdown.
Antonia’s financial cases usually involve complex and/or multi-jurisdictional legal and financial issues, including all manner of offshore trust and corporate structures, dynastic wealth, and both alleged and actual non-disclosure of significant assets by one party.
Every family law case is unique. Therefore, Antonia works with clients to identify their objectives and agree upon a strategic approach tailored to their needs, whether through alternative dispute resolution or by way of court proceedings where appropriate. She is always conscious of the potential costs of the process – both financial and emotional – and takes a pragmatic approach to her cases.
Antonia is incredibly proud to have won Family Lawyer of the Year – Partner (Bronze) at the Citywealth Future Leaders Awards 2025.
What Georgina says about Antonia: I could not be happier to welcome Antonia and her incredible legal brain to the team.
