If the abortion is a regular hospital, it must be signed by the family. Of course, family members may be their own objects, parents-in-law or their own parents. If individual clinics are irresponsible, parents may not need to sign.
In this case, it is recommended to make it clear to your parents, not to hide it from your parents. Generally speaking, if you choose a regular hospital for abortion surgery, you generally need the guardian's signature. For your safety, you'd better know it from your parents. And now is the early stage of pregnancy, you can abort the child by abortion, but you need to sign the operation, so you'd better tell your parents.
