In this article, we aim to present essential aspects regarding the legal responsibility of the lawyer, with a particular focus on the activity of legal representation and assistance, without claiming to comprehensively address the chosen topic. According to art. 3 para.

However, during their activity, the lawyer may be held criminally, civilly, disciplinarily, or administratively liable, depending on the nature of the unlawful act committed, which we will assess to what extent by referring to the legal provisions mentioned above. Therefore, through this article, we aim to provide, in a general manner, information regarding the legal responsibility of the lawyer that may arise in the exercise of legal representation and assistance activity.
