Do parents who use a surrogate mother as a "host" have to legally adopt the child?

If the eggs and sperm of the parents are being used and they are just "renting" (for lack of a better word) the womb of the surrogate, do they have to legally adopt the child after it is born?

There's no one answer to this; it depends on where the surrogate lives (or where the birth takes place). Even within the U.S., it varies totally from state to state.



Some places just require certain paperwork to create a "pre-birth order" putting the biological parents on the birth certificate, while others will require a full adoption. I'm fairly sure, but it's been a little while, that in some states even non-biological parents via surrogacy can apply for the pre-birth order.Do parents who use a surrogate mother as a "host" have to legally adopt the child?
Traditional Surrogacy:



The Carrier would be using her own egg, and therefore have a genetic link to the child. In this arrangement, the Surrogate agrees to be inseminated with the sperm of the Intended Father. After the birth, the surrogate agrees to terminate her parental rights, and the Intended Mother does a step-parent adoption.



there are a few different types of surrogacy though and some the surrogate will have no biological link to the baby.
