Criminal law does not require lawyers to defend themselves.

In most cases, the defendant or the defendant can be his own lawyer to defend himself in court. This situation is usually called "justifiable defense" or "justifiable defense". However, before considering becoming a lawyer to defend himself, individuals should carefully weigh the pros and cons, because this may adversely affect cases involving complex legal affairs.

First of all, one of the advantages of choosing your own lawyer is the flexibility of legal procedures and evidence collection. Being a lawyer by yourself can ensure that individuals have a deep understanding of their own cases and have the opportunity to directly participate in every stage. Defendants or defendants can freely arrange investigation measures, provide necessary evidence, choose defense strategies and have direct dialogue with the court. This direct connection and dominant position can help the defendant or the defendant better understand and pay attention to his case.

Secondly, being a lawyer by yourself can also save money for the defendant or the defendant. Hiring a lawyer can cost a lot of money, especially in long or complicated cases. By exempting the lawyer's fee, the defendant or defendant may reduce the financial burden and have more resources for other aspects, such as hiring professionals as witnesses or experts to provide testimony to further support their defense.

However, being a lawyer by yourself is not the best choice for all cases, especially for those who are not familiar with legal procedures and professional knowledge. Here are some disadvantages to consider:

First of all, being a lawyer by yourself may bring insurmountable difficulties to the defendant or the defendant. The legal system is complex and highly technical, and it may be extremely challenging for non-professionals to understand and apply legal principles. Lawyers in the court have profound legal knowledge and experience and can formulate corresponding defense strategies according to the specific requirements of the case. Being a lawyer by yourself may lead to misunderstanding of legal provisions and procedures, thus affecting the effectiveness of defense.

Secondly, being a lawyer alone may interfere with a fair and objective defense because of emotional or emotional factors. In court, lawyers usually handle cases in a calm and objective way, and are not affected by emotions and personal positions. However, when an individual defends himself, he may be disturbed by his own feelings or emotions, which may lead to the defense being no longer objective or effective.

In addition, compared with experienced lawyers, individuals may lack skilled debating skills and court strategies. After a long period of training and practice, lawyers have the skills of debate and court, and can better grasp the core elements of defense: questioning witnesses, defending statements and arguing legal issues. Being a lawyer alone may lead to the failure to make full use of these strategies and have a negative impact on the outcome of the case.

Finally, being a lawyer alone may put a lot of pressure on your time and energy. Court procedures and case preparation are usually very time-consuming, requiring a lot of research, preparation of documents, collation of evidence and so on. Being a lawyer involves a lot of work and may neglect other important daily affairs.

In addition, the tension and pressure during the court session may adversely affect the mental health of individuals.

To sum up, being able to defend yourself as a lawyer is one of the rights in court, but the related advantages and disadvantages must be weighed. Being a lawyer by yourself may bring more flexibility and save money, but it may also face challenges such as lack of legal knowledge, emotional interference, lack of debating skills and time pressure. Before making a decision, the defendant or defendant should consult a professional lawyer to obtain accurate legal advice and determine the best defense strategy.
