Wyo. Stat. § 35-1-410

(a) A certificate of birth for each live birth which
occurs in this state shall be filed with the local registrar of
the district in which the birth occurs within ten (10) days
after such birth and shall be registered by the registrar if it

certificate, secure the signatures required by the certificate
and file it with the local registrar. The person in attendance
will certify to the facts of the birth and provide the medical
information required by the certificate within seven (7) days
after birth. If the attendant has not signed the certificate
within seven (7) days of the date of the birth, the person in
charge of the institution or a designated representative shall
complete and sign the certificate.

     (c) When a birth occurs outside an institution, the
certificate shall be prepared and filed by one (1) of the
following in the indicated order of priority:

          (i) The physician in attendance at or immediately
after the birth, or in the absence of such a person;

          (ii) Any other person in attendance at or immediately
after the birth; or

          (iii) The father, the mother, or in the absence of
the father and the inability of the mother, the person in charge
of the premises where the birth occurred.

     (d) For purposes of birth registration, unless a court of
competent jurisdiction orders otherwise at any time or except as
provided in subsection (e) of this section, the woman who gives
birth to the child shall be deemed the mother.

     (e) Upon the birth of a child under a gestational
agreement, the intended parents of the child born under the
gestational agreement shall be deemed to be the mother and
father of the child, including for purposes of birth
registration and the birth certificate, upon satisfying the
following conditions:

          (i) Submission of a complete application by the
intended parents as the state office of vital records services
prescribes; and
