a highly motivated and commercially minded junior barrister

Tom Vonberg
Year of Call 2004

Tom is an English barrister based in London and the North of England.

He has a significant amount of advocacy experience in a wide variety of litigation at all levels of tribunal. Tom has conducted countless final hearings as a sole advocate. He has also worked with senior QC’s at Devereux Chambers and elsewhere in cases of particular importance.

Tom’s principle areas of work since he has been at Devereux have involved complex or high value injury litigation, professional negligence and all manner of insurance coverage disputes, particularly where there has been dishonest conduct or non-disclosure. Increasingly, whether at the costs-budgeting stage or after trial, Tom receives instructions where legal costs are contested. A particular theme in Tom’s professional negligence work of late involves claims against lawyers for negligent conduct of litigation. 

Tom acts equally for claimants and defendants. He is routinely instructed by many of the well-known law firms and insurers who are active in his specialist fields.

Before coming to the independent bar, Tom was an employed barrister in commercial disputes at a leading offshore law firm. There he dealt with a number of cross-jurisdictional cases, many of which concerned financial misconduct. Now, in independent practice, Tom is at ease working with document heavy cases or where there are a number of instructed lawyers or experts. Tom is approachable and available to his clients whenever he is required.

In addition to London, Tom has a home in North Yorkshire and he spends some of his time in the legal centers of Manchester, Leeds and Birmingham. 

Tom is an active member of a number of professional organisations and where he is developing valuable professional contacts. His memberships include, the Professional Negligence Bar Association, the Professional Negligence Lawyers Association, the British Insurance Lawyers Association and the Young Fraud Lawyers Association.

Tom has provided further details of some of his representative litigation in the pull down menus below. Party names have been redacted where cases remain confidential. Examples of his very recent work are included in this overview section.


Current or very recent personal injury and clinical negligence instructions have included:

  • Multi-party claim on behalf of seriously injured students and in respect of fatalities following a bus crash abroad. Tom is acting without a leader and liability has now been compromised, whilst quantum continues to be litigated in the High Court;
  • Product liability claim following helicopter crash in the UK but where maintenance was carried out in the U.S (led by Rob Weir QC);
  • Fatal accident claim on behalf of a dependent minor and which, unusually, in 2014 went to a contested quantum trial and at which the claimant beat the defendant’s and (narrowly) his own Part 36 Offers;
  • Catastrophic spinal and brain injury claims; Tom has been led by both Steve Killelea QC, Rob Weir QC and Pete Edwards in chambers on high value matters which have included, variously, arguments over contribution or Health and Safety law;
  • High Court defence of a brain injury claim where there was compelling surveillance evidence and which settled on the first day of trial (led by a silk outside chambers, Andrew Hogarth QC);
  • Numerous claims and defences in clinical negligence and especially in the fields of obstetrics, orthopedics, cardiology, accident and emergency, cosmetic and dental surgery. Commonly, these cases involve tricky issues of causation and this is a topic he lectured on in 2014 to a national law firm. He is currently acting for a claimant along with Rob Weir QC in a lower limb orthopeadics case where the clinical outcome has led to a complete loss of mobility. Recently Tom has acted successfully for private surgeons in London who have been sued for “disappointing outcomes” following cosmetic surgery;
  • Successful defences at trial to motor insurance fraud. Over the last few years Tom has been instructed by a number of insurers who appreciate combative advocacy and a forensic attention to the detail of the case.

Professional negligence

Professional negligence work also forms a substantial part of Tom’s practice. Most often he is by instructed by Defendants, although he has acted for Claimant’s in a number of cases against other lawyers and, in particular, brokers. Cases during 2013 and 2014 of interest are:

  • Several defences to broker’s negligence claims involving alleged breach of ICOBS in matters ranging from arrangement of fleet policies to professional indemnity cover;
  • Defences of IFA’s, typically sued for alleged negligent assessment of the client’s risk profile;
  • Solicitors negligence claims for negligent conduct and under-settlment and often in the context of personal injury litigation;
  • Multi-party conveyancing claims against Solicitor’s complicit in obtaining lending by way of “gifted” deposits;
  • Claims against a conveyancing Solicitor in the East of England for negligently advising completion, without ensuring adequate contractual protection, when the development was incomplete and the developer subsequently went into liquidation;
  • Claims handlers negligence – settlement at an undervalue, claims brought by the insurer. 


Tom is often involved in discreet of insurance law disputes but it is of use also as a cross-over expertise in his his personal injury and professional liability work. Recent instructions have included:

  • Successful appeal to the Financial Ombudsman Service against insurer’s refusal to indemnify insured under household policy against an underlying claim for in excess of £1m;
  • Insurer’s pre-action disclosure application of documents against third party insurer, for the purpose of declaratory proceedings to avoid a policy of motor insurance pursuant to Section 152(2) of the RTA 1988 (with Rob Weir QC);
  • Defence to Part 20 Claim for an indemnity claimed by a computer company against their insurer;
  • Brokers’ indemnity claim against PI insurer where the argument was as to aggregation following mis-selling of Keydata financial products (with Colin Wynter QC). 
  • Coverage issues following property damage. The largest series of claims Tom was involved in followed the Buncefield explosions.
