In 1993, upon returning to the UK, Asserson joined Bird & Bird, where he became the Global Head of International Litigation. His clients included the UK government, other sovereign states, multinational corporations, and high-net-worth individuals.

Landmark cases
Trevor Asserson was the lead lawyer in Don King Productions Inc. v Warren (December 1998), a major dispute between the leading boxing promoters in the US and the UK.

Representing King in this action, Asserson, a senior litigation partner at Morgan Lewis & Bockius, had previously acted for King during the prolonged court proceedings following the collapse of his business arrangement with British promoter Frank Warren, which culminated in a $12 million out-of-court settlement. Asserson highlighted King's philanthropic efforts, noting his contributions to Jewish charities in America, including a $1 million donation—$100,000 of which was personal—to Kisharon, a London school for Jewish special-needs children.

In 2004, the New York Times reported that Asserson represented Rachel Ehrenfeld. Ehrenfeld's British distribution deal for her new book, "Funding Evil: How Terrorism Is Financed and How to Stop It", was canceled due to a legal threat from one of the Saudis she mentioned.

In 2012, Asserson represented jailed Israeli solicitor Israel Perry in relation to one of the largest cases ever brought by the Serious Organised Crime Agency (SOCA), seeking to seize and gain disclosure of worldwide assets worth hundreds of millions of pounds. Asserson challenged both orders on jurisdiction grounds, referring to the "[very concerning] effect of this novel and far-reaching interpretation of UK law" on people who retain sensitive client information. The matter went to the Supreme Court on two separate issues, where the UK Government was defeated 9–0 and 7–2 respectively. Later, in a remarkable instance of the government utilizing its judicial power, the UK Government passed an amending law in attempt to reverse the Supreme Court result. However, the claim was subsequently abandoned and damages paid to Perry.

Asserson represented the Greek government's interest in Macedonia's largest oil refinery, in the case of Okta Crude Oil Refinery v Mamidoil-Jetoil Greek Petroleum Company, in 2003. The case led to various reported decisions, creating numerous precedents.

In 2009, Asserson successfully defended Sonja Kohn, the main defendant in Madoff Securities International Ltd (MSIL) v Raven & Ors. The Madoff estate sought to recover from Kohn c.$59 billion arising out of introductions to the Madoff Ponzi scheme. The Madoff estate paid legal costs on an indemnity basis.

Asserson represented Adath Yisroel Burial Society (AYBS) in 2018, bringing three separate applications for judicial review against Mary Hassell, Senior Coroner for Inner North London, in what came to be known as the Coroner Case. Hassell acted in a way that was discriminatory against the needs of the Muslim and Jewish communities. The case was highlighted in the British media, with mentions by Prime Minister Theresa May during Prime Minister's Questions and by then-Mayor of London, Sadiq Khan, among others. The High Court found Hassell's practice to be "unlawful, irrational" and "discriminatory", and its ruling was hailed as a "victory by AYBS is a victory for the cause of diversity throughout British society." Asserson was selected as Lawyer of the week in The Times for this work.

Trevor Asserson was behind the claim that obtained the "largest ever sum recovered by a Human Rights Act claim", representing 18 claimants by launching a successful judicial review and Human Rights Act claim against the Department for Energy and Climate Change for losses stemming from earlier than expected cut in subsidies.

Public activities
In 2000, Asserson founded BBCWatch to analyse BBC media coverage of the Middle East. Between 2000 and 2006, BBCWatch published six studies detailing the BBC's systematic bias against Israel. Asserson appeared on public debates, TV, and radio, concluding that the 'BBC's coverage of the Middle East is infected by a widespread antipathy toward the country'. BBC held a public inquiry into its Middle East coverage and created a senior editorial post to advise on its Middle East coverage.

In 2008, Asserson released a report alleging that the BBC Arabic radio exhibited bias during the 2006 Second Lebanon War, favoring Iran and Hezbollah.

Asserson also acted for CAA in its claim against Bristol University, after prof. David Miller's conduct left Jewish students feeling "unsafe and unprotected." As a result, the university launched an investigation which led the decision to terminate Miller's employment.

In 2023 Trevor published a series of articles relevant to the public debate in Israel concerning potential Judicial reforms which threatened the independence of the Israeli courts.

In 2023, Trevor Asserson launched a legal action against the BBC, accusing it of biased coverage of the Gaza conflict in violation of its editorial guidelines. He asserts that the BBC's report on an explosion at Al-Ahli Arab Hospital, initially blamed on Israel, typifies ongoing biased reporting. Asserson argues this reflects a systemic bias within the BBC that undermines its duty to impartiality.
