What is Legal AI and how is it transforming law firms? 

Although many existing laws such as the GDPR and Data Protection Act 2018 are relevant to its use, there currently aren’t many laws specific to AI. However, as the technology has continued to evolve, so have global regulations. 

The EU Artificial Intelligence Act was the world’s first comprehensive regulation on AI. It came into effect on 1 August 2024, with provisions gradually coming into operation over the next 6 to 36 months. The AI Act aims to manage the associated risks by prohibiting unacceptable usage of the technology, assigning legal responsibility, addressing copyright concerns, and outlining compliance requirements to regulate the use of AI throughout the European Union. 

While it’s a relatively new technology, the rate at which artificial intelligence is developing, as well as the fast adoption by a wide range of sectors, means that existing laws and regulations aren’t sufficient to cover the expanding use cases of AI. As artificial intelligence is developed and adopted by more and more industries, global authorities will need to create more comprehensive regulatory practices to protect privacy and security, and minimise risks. 

Let’s explore some of the applications of AI in law firms, and the benefits they offer. 

1. Efficiency and automation 

AI is able to quickly highlight key clauses and potential issues in contracts, making management more efficient. Machine learning tools can also help to automate document retrieval and review processes by using classification models, saving time on simple administrative tasks. These efficiencies free up legal professionals to focus on higher-value work. 

2. Enhanced legal research

Machine learning supports legal research by quickly analysing vast amounts of information, identifying relevant case law and extracting key insights. Similarly, GenAI can accelerate drafting by creating content within specified parameters, enhancing the speed and accuracy of legal document preparation. 

3. Predictive analytics 

AI in law firms can assess the likelihood of a particular outcome by analysing past verdicts and negotiations. This helps them to meet the expectations of a competitive market by leveraging predictive insights and making data-driven decisions. 

4. Litigation and e-discovery 

AI tools can support your legal firm by gathering data and insights when preparing evidence for litigation, significantly enhancing e-discovery efficiency. By being able to scrape huge volumes of data, AI reduces the time and costs associated with traditional evidence review processes. 

5. Improved client experience 

There are many implementations of AI that can help your legal firm to increase response times and improve client engagement. For example, adding a chatbot or virtual assistant to your website to answer common questions instantly. The automation capabilities of AI can also help legal professionals to spend less time on repetitive tasks and more time building client relationships. 

As firms move from understanding AI to applying it in practice, the question often becomes what good AI adoption actually looks like. From integration and governance to how technology supports everyday legal work, AI maturity is about more than individual tools alone – it’s about using AI in a way that is consistent, well‑governed, and aligned with how the firm operates.

AI can feel complex at first, but understanding what it does – and where it fits – is the foundation for using it effectively. By approaching AI with clarity rather than hype, law firms can make informed decisions about how and when AI supports their people, their clients, and their ways of working.
