Wyoming Statute 35-1-411. Name of father on birth certificate.
(a) If the mother was married either at the time of conception or birth of child, or between conception and birth, the name of the husband shall be entered on the certificate as the father of the child, unless:
(i) Paternity has been determined otherwise by a court of competent jurisdiction; or
(ii) The husband signs an affidavit denying that he is the father and the mother and the person to be named as the father sign an affidavit of paternity under this section. Affidavits may be joint or individual or a combination thereof, and each signature shall be individually notarized. The name of the person signing the affidavit of paternity shall be entered as the father on the certificate of birth.
If the mother provides incorrect or false information concerning her marital status at the time of her child’s birth, it may take a court order to correct the birth certificate once it has been filed with Vital Statistics Services.
Mother’s Marital Status on the Birth Certificate
When completing the “Mother’s Worksheet for Child’s Birth Certificate,” the mother is asked to provide information about her marital status and the child’s natural father. The following items MUST be answered very carefully; failure to do so will impact the paternity establishment for the child. Simply because the mother lists the father’s name on the worksheet, does not guarantee he will be named at the time the record is registered.
Mother’s Marital Status: (This is question 7 on the worksheet)
- Was the mother married to anyone at the time of conception, birth or anytime in between? Choose YES or NO.
- If the mother was MARRIED at the time of birth, the mother needs to mark YES.
- If the mother was going through a separation or divorce, but not yet divorced, she must check YES.
- If YES, is her husband the father of the child? Choose YES or NO. This question is asking if your husband is the father of the child.
- If the mother was MARRIED and her husband IS the father, the mother needs to mark YES.
- If the mother was MARRIED and her husband IS NOT the father, the mother needs to mark NO.
Paternity Acknowledgement: (This is question 8 on the worksheet and only needs to be answered if the mother WAS NOT MARRIED to the natural father.)
- Has the father signed an Affidavit Acknowledging Paternity? Choose either YES or NO.
- If the mother WAS NOT married at the time birth and wishes to name the father on the child’s birth certificate, this must be answered YES. Both the mother and natural father are to complete the Affidavit Acknowledging Paternity and sign in front of a Notary Public. For each signature, there must be notary seal.
- If the mother and natural father have not signed an Affidavit Acknowledging Paternity, the father can’t be listed on the certificate until the affidavit is completed and filed with Vital Statistics Services.
Paternity Denial: (This item only needs to be answered if the mother WAS MARRIED but the husband is not the natural father of the child)
- If the mother was married, has her husband signed an Affidavit Denying Paternity? Choose either YES or NO.
- If the mother was married, the husband is NOT the natural father of the child, and the natural father wishes to be named on the certificate as the father. The mother and natural father must complete an Affidavit Acknowledging Paternity as mentioned above and the husband must complete an Affidavit Denying Paternity and sign in front of a Notary Public. Both affidavits are legal documents and need to be submitted to Vital Statistics Services.
