Whether the induced abortion operation needs the signature of family members depends on the specific situation of the patient. If the patient/kloc-is over 0/8 years old and has self-care ability, and no guardian is needed, it can be signed by family members, friends and colleagues. As for who to sign, it's entirely up to you. You can appoint an agent to sign. If the patient is younger than 18 years old, or has no self-care ability, and needs a guardian for daily study and work, the patient or his guardian needs to sign the induced abortion operation, and no one else can sign it. Because the patient has no self-care ability, there is no way to appoint an agent. In this case, the patient can ask his guardian's parents, or his siblings to sign, but others can't.
