Let's use the proper terms first. It is common to see in the media the term " belly for rent in the UK " or " surrogacy in the UK ” when the bellies and mothers are not rented. for that reason it is not correct to use concepts such as Substitute mother or belly for rent. The correct term is surrogacy. A Substitute mother is a woman who agrees, by contract, to become pregnant with the aim of begetting and giving birth to a child who will be raised as their own child by a couple or single person. It is a misnamed "surrogacy" through a pregnancy contract for substitution. For more information click here.
