Lawyer vs. AI: When Is AI Enough, and When Do You Need Legal Advice?

Years ago, when faced with a legal question, it was possible to search for information on Google, consult specialized websites, or contact a lawyer by phone, email, or WhatsApp. These options still exist today, but there is now an additional alternative: artificial intelligence. Within seconds, it is possible to get an explanation of what a simplified stock company (S.A.S.) is, compare two types of contracts, or generate a draft clause from a few instructions.
However, the fact that a tool can answer a question or produce a document does not mean its result is always correct or that it takes into account the particularities of each case. For that reason, the question is not simply whether artificial intelligence can perform legal tasks, but when it is enough to use it and in which situations legal advice from a lawyer becomes necessary.
In this article, we analyze what kinds of legal questions can be handled with artificial intelligence, what its main limitations are, and in which situations professional legal judgment is especially important. We also examine how the two alternatives can complement each other and what to consider when deciding between using AI on your own or hiring legal counsel.
How Does AI Work for Legal Questions?
To understand what artificial intelligence can contribute to a legal question and what its limitations are, the first step is to have a basic notion of how AI works. This makes it possible to understand why it can explain legal concepts, compare alternatives, and draft documents in seconds, but also why it can give incorrect answers or overlook important aspects of a case.
Artificial intelligence is a set of techniques that allow a computer system to perform tasks that normally require human intelligence, such as recognizing images, translating, or answering questions. Today, many of these tools are based on machine learning, through which systems are trained on large amounts of data to identify patterns and use them when processing new information.
In the case of conversational assistants such as Claude or ChatGPT, the technology is based on language models trained on large volumes of text. During training, these models learn patterns in language and relationships between words and concepts. Then, when given an instruction, they generate a response piece by piece, calculating which continuation is most likely given the context and the patterns they have learned.
Important note: this explanation was, in fact, built using Claude and ChatGPT.
This functioning makes it possible to produce coherent texts, explain concepts, summarize documents, and prepare drafts based on the user's instructions. However, a coherent answer is not necessarily a correct answer. The model generates content from the patterns it has learned and the context available, so it may present false information, cite nonexistent rules, or rely on provisions that are no longer in force, all in a convincing tone.
For this reason, when using AI to resolve a legal question, it is important to distinguish between obtaining an initial explanation and verifying that the information applies to the specific case. The ability to draft an answer or identify a possible solution does not guarantee that the system has correctly interpreted the facts, consulted the current regulations, or considered all the relevant legal consequences.
Advantages of AI
Once we understand how artificial intelligence works, it is possible to see why it has become a useful tool for approaching legal topics. Its speed, ease of use, and low cost make it possible to resolve initial questions and understand concepts without needing professional advice for every question. Its main advantages include the following:
Immediate Answers to Specific Questions
AI lets you ask questions at any time and receive an explanation within seconds. This speed is useful for understanding legal terms, comparing concepts, or preparing questions before a meeting with a lawyer.
Ease of Use
There is no need to know legal terminology to use these tools, since questions can be asked in everyday language. It is also possible to ask for clarification, request examples, or rephrase a question until a topic is better understood.
Lower Cost
Many artificial intelligence tools offer free versions or low-cost subscriptions. For that reason, to explore a legal topic or understand a general question, they can be an economical alternative to a professional consultation. However, the initial savings should be weighed against the risk of being wrong and the need for an answer that is legally applicable to the specific case.
Disadvantages of AI
Although artificial intelligence offers advantages in speed, ease of use, and cost, these features do not guarantee that its answers are correct or suitable for a particular legal situation. Therefore, before using it to make decisions or prepare legal documents, it is important to understand its main limitations and the risks that can arise when its results are relied on without verification. In that sense, it is important to consider the following disadvantages:
It Generates Coherent Text, but Does Not Guarantee a Proper Evaluation of the Case
A language model generates responses from learned patterns and the context it receives. Although it can analyze information, compare alternatives, and identify potential problems, it does not necessarily consider all the relevant circumstances or the legal and commercial consequences of a decision. For example, an answer may correctly explain a general rule but turn out to be unsuitable for a company because of its characteristics, its activity, or the obligations that apply to it.
The Result Depends on the Question and the Context
The quality of the answer depends, to a large extent, on the information provided and on how the question is framed. However, identifying which data is relevant and which additional questions should be asked requires, in many cases, legal knowledge.
If the person asking the question is unaware of how relevant these factors are, they may not include them in their instructions and may receive an incomplete answer.
It Can Produce Incorrect Information in a Convincing Way
Language models can produce false or outdated information, such as citing an article that does not exist, mentioning a requirement that is no longer in force, or stating an incorrect deadline. The problem is that these errors can appear in a well-written answer, with an apparently logical explanation and a confident tone, which makes them difficult to identify without enough knowledge to cross-check the information.
This limitation is especially relevant when AI is used in an area one is not familiar with. An experienced person can quickly spot an error in their own field, while someone without that knowledge may accept the answer as correct.
In legal matters, a mistake that goes undetected in time can contribute to a poorly structured company, a clause that does not protect the intended interests, or an application that does not meet the applicable requirements.
It Can Pose Confidentiality Risks
Another important issue is the information entered into these tools. When using an AI platform, different data processing terms, privacy policies, and settings may apply depending on the service and the type of account. Therefore, before sharing client information, business documents, or personal data, it is necessary to review how that information is processed and what protection measures the tool offers.
In Colombia, the Superintendence of Industry and Commerce (Superintendencia de Industria y Comercio, SIC), as the personal data protection authority, issued External Circular 002 of 2024, which sets out guidelines on the processing of personal data in artificial intelligence systems and notes that Laws 1266 of 2008 and 1581 of 2012 also apply to that processing.
In the legal field, this precaution is especially relevant because the information may be subject to duties of confidentiality and professional secrecy. In the case of lawyers, Article 34 of Law 1123 of 2007 (Colombia's Disciplinary Code for Lawyers) classifies as a disciplinary offense the disclosure or use of secrets entrusted by the client, unless the client has given written authorization or disclosure is necessary to prevent a crime.
Can AI Replace Lawyers?
The advantages and limitations of artificial intelligence make it possible to distinguish between the legal tasks it can support and those that require a broader evaluation of the case. Therefore, to answer whether it can replace a lawyer, it is necessary to distinguish between performing specific tasks and taking responsibility for a legal decision.
For certain tasks, yes. AI can summarize documents, draft preliminary versions, organize information, or explain concepts. These functions can reduce the time spent on support activities that previously required considerable work.
However, this does not mean it can replace the professional judgment needed to decide which structure is appropriate, which risks to take, what to negotiate, or which terms to include in an agreement. These decisions depend on the circumstances of the case, the client's objectives, and the legal and commercial consequences of each alternative. In addition, someone must take professional responsibility for the advice provided.
What Can AI Not Replace?
Although artificial intelligence can support many legal tasks, there are aspects of legal advice that go beyond generating answers or documents. To understand this difference, it is worth examining three elements that remain fundamental in a lawyer's work: professional judgment, human contact, and responsibility for the advice provided.
Professional Judgment
Choosing between two corporate structures, deciding how a foreign investor should enter, or assessing the risk of a clause requires considering the facts, the applicable rules, the practices of the authorities, and the client's objectives. AI can identify alternatives and explain their characteristics, but determining which one is more suitable requires evaluating how those factors relate to each other in the specific case.
Human Contact
Legal matters also tend to involve personal relationships and negotiation processes: partners with different interests, investors with their own expectations, and counterparties with positions to defend. A lawyer can understand that context, identify the interests at stake, and take part directly in the negotiation to seek terms that respond to the client's objectives. AI can help prepare for that interaction, but it does not replace the professional's representation or direct communication.
Professional Responsibility
A lawyer must act in accordance with their professional duties and is answerable for their actions as established by law. AI, for its part, does not assume professional responsibility for the content it generates. Therefore, when a decision is made on the basis of an incorrect answer, it is essential to determine who reviewed the information, how it was used, and who made the decision. Having legal advice means there is a professional in charge of evaluating the case and answering for their own actions.
Lawyer + AI: Efficiency With Judgment
Lawyers are no strangers to the use of artificial intelligence. These tools can be incorporated into legal work to speed up document review, organize information, prepare drafts, and compare alternatives. However, their usefulness depends on how they are integrated into the service and on professional review of their results. The question is not only how much work AI can do, but how to take advantage of that efficiency without losing the legal judgment each case requires.
Artificial intelligence can add value to legal work when it is used to speed up support tasks, while the lawyer remains responsible for reviewing the results and making the decisions that require professional judgment. This combination makes it possible to work more efficiently without confusing the automation of certain tasks with the replacement of legal advice.
Efficiency with judgment: AI makes it possible to process information, prepare drafts, and speed up repetitive tasks, while the lawyer evaluates the alternatives and determines what is appropriate for the case.
Fewer mechanical errors: it can help check the consistency of definitions, cross-references between clauses, and differences between versions of a document. These checks, however, require human review before the document is used.
Adaptability: the professional adjusts the work to the client's circumstances and objectives, while AI makes it easier to review alternatives and prepare documents in less time.
How Does AI Affect the Billing Model for Legal Services?
The adoption of artificial intelligence also raises questions about the value of legal services and how fees are calculated. If a tool can complete in one hour a task that used to take three, it is fair to ask whether time spent is still the most appropriate criterion for determining how much that work is worth. In many cases, the value to the client depends more on the solution obtained, the judgment applied, and the risks managed than on the number of hours needed to complete the task.
In that sense, at JG Lawyers we use a flat-fee model for one-off legal services, whose price is set according to the scope of the service engaged, and the AIE Legal Credit System. Under this system, the client uses credits to access the services included in their plan, in accordance with the contracted terms.
In this way, both models seek to ensure that the financial terms reflect the service engaged and the value it provides to the client, rather than depending exclusively on the time needed to carry out each task.
How does the Legal Credit system work?
Conclusion
Artificial intelligence is a useful tool for understanding legal topics, preparing questions, and speeding up support tasks. However, using it does not remove the need to evaluate the circumstances of each case, make decisions with professional judgment, and have someone who takes responsibility for the advice provided.
The question is not simply whether to choose AI or a lawyer, but knowing when it may be enough to use a technology tool and when the particulars of a decision make a professional's involvement necessary.
Technology also invites us to rethink how legal services are delivered and billed, giving greater weight to efficiency, the scope of the service, and the value created for the client.
