Legal analysis: children whose fathers have been in prison can take the lawyer exam. Because there are three situations in which a lawyer's practice license is not issued: 1, no capacity for civil conduct or limited capacity for civil conduct; 2. Those who have received criminal punishment, except for negligent crimes; 3. Being expelled from public office or having his lawyer's practice certificate revoked. Criminal punishment generally refers to the person, not including relatives. As long as the above situation is not met, even if the father has been in prison, the child can take the bar exam.
Legal basis: Article 7 of the Lawyers Law of People's Republic of China (PRC) shall not issue a lawyer's practice certificate if the applicant is under any of the following circumstances: (1) No capacity for civil conduct or limited capacity for civil conduct; (2) Having been subjected to criminal punishment, except for negligent crimes; (3) Being expelled from public office or having his lawyer's or notary's practice certificate revoked.
