Daria is a highly demanded junior with a thriving commercial chancery practice. Her expertise is broad and varied, encompassing civil fraud, contentious trusts and estates, art and cultural property work, company law, insolvency, property law and a full range of domestic and offshore commercial disputes. Daria is also able to advise and represent clients on issues of public law and planning, especially those arising in the broader context of commercial and insolvency proceedings.

Daria very frequently works with lawyers and clients from other jurisdictions and advises and acts in matters involving international and conflict of laws elements. She is accustomed to working closely with foreign lawyers and addressing issues of foreign law.

She appears in the county courts, the land tribunals and in the High Court and in arbitrations and mediations, both as sole counsel and part of a larger team (she has, on occasion, been led by no fewer than 4 silks at once, on the same case). She frequently appears as sole counsel, often against silks, or silk and junior teams, in high-value and complicated matters.

Daria also has extensive appellate experience, having worked in her early days at the Court of Appeal as the judicial assistant of Sir Terence Etherton (then the Chancellor) for a full year and having since acted in myriad appeals, both as appellant and as respondent.

She has been described by clients as “a fantastic advocate”, “fearless”, “extremely persuasive, especially on difficult issues”, “a rottweiler in court”, “a clever and impressive tactician”, and “an all‑round superstar”. Her drafting, especially skeleton arguments and pleadings have been described by clients as “superb”, “very impressive” and “a work of legal and literary genius”, with many clients saying they were “delighted” and “over the moon” with the results obtained by Daria and a returning client being “always confident that she will get me the best result”.

Daria often receives praise from the judiciary, with a High Court judge remarking that “Ms Gleyze’s clients sailed close to the wind. But Ms Gleyze’s eloquence persuaded the trial judge and she has also persuaded me on this appeal”. A senior judge also commented, in allowing 3 times more in costs than the cap imposed by the rules: “I found Ms Gleyze’s skeleton and submissions extremely helpful and I consider her fees justified in their entirety”.
