Legal analysis: if the client 18 years old, he can choose the signature of his family or friends and colleagues. If the person concerned is under the age of 18, the painless abortion must be signed by his family or guardian, and no one can sign it on his behalf. Because painless abortion has certain risks, in order to ensure the safety of the parties, all risky operations need to be signed by family members or their guardians. Painless abortion does not need the signature of family members, because Chinese laws stipulate that women have the right to bear children, and the embryos of painless abortion are relatively small, not yet three months old. Therefore, it is ok for women to perform surgery by themselves, and general hospitals do not need family members to sign. However, considering that the fetus is born by both men and women, we must carefully consider whether to terminate the pregnancy before the operation. It is best for husband and wife to discuss it together, and then go to the hospital for surgery after discussing it at home, otherwise it will easily lead to tension and contradictions between husband and wife.

Legal basis: Article 51 of the Law of People's Republic of China (PRC) on the Protection of the Rights and Interests of Women and Children. Women have the right to have children in accordance with relevant state regulations, but also have the freedom not to have children.
