Legally, yes, at least for a while. No Utah law requires a pregnant woman to tell the man who got her pregnant, and there is no court that will order her to. But the question usually comes from a woman who is thinking past the pregnancy to the child, and there the answer changes. Once a child is born, the father has rights that do not depend on whether he was told, the child has a right to support from both parents, and a mother who wants to keep the father out permanently will find that Utah law gives her fewer tools than she may expect, except in one specific situation. Here is how it actually plays out.
During the pregnancy
A woman has no obligation to inform the father, and he has no legal right to be informed. He cannot compel her to disclose a pregnancy, cannot obtain a court order about prenatal care, and cannot stop her from making her own medical decisions. If she chooses to tell him, she can do it on her own terms.
Utah does, however, give an unmarried father a way to protect his rights before the birth, and this is where secrecy starts to have consequences. A man who knows or suspects that a woman he had sex with is pregnant can file a paternity action and a notice with the Office of Vital Records during the pregnancy. If he does, his consent is required for any adoption and he is entitled to notice of what happens to the child. If he does not, because he does not know or does not act, he may lose those rights. Our article on the rights of unwed fathers in Utah explains the filings.
If the plan is adoption
This is the one situation where Utah law allows a mother to move forward without the father’s involvement, and it is deliberately designed that way. Under the Utah Adoption Act, an unmarried father’s consent to the adoption of a child six months old or younger is not required unless, before the mother signs her consent to adoption, he has filed a paternity action in Utah, filed a sworn affidavit committing to full custody and describing his plan for the child, filed a notice of the paternity proceeding with Vital Records, and paid a reasonable share of pregnancy and birth expenses to the extent he could.
A father who has not done those things by the time the mother consents has no legal say in the adoption, and Utah law does not require anyone to warn him. The mother may consent as early as twenty-four hours after the birth. A mother who intends to place the child for adoption and does not want the father involved is on solid legal ground in Utah, as long as the adoption follows the statute. Fathers who have been on the other side of this rule have challenged it in court for years, and the rule has held.
If the father did file before she consented, the adoption cannot proceed without him, and the mother should assume he will find out the moment the adoption agency or attorney checks the Vital Records registry, which they are required to do.
If the plan is to raise the child
Here secrecy has a much shorter shelf life, for three reasons.
The child is entitled to support from both parents. If the mother ever applies for state assistance, including Medicaid for the child, the Office of Recovery Services will require her to identify the father so it can establish paternity and pursue support. A mother who refuses to cooperate can lose benefits. Even without public assistance, the child’s right to support does not go away because the mother chose not to pursue it, and a later custody case will raise it.
The father can establish paternity whenever he learns of the child. There is no deadline for a father to file a paternity action in Utah when no adoption is involved. A father who learns about a five-year-old can file, obtain genetic testing, and seek custody and parent-time. The court will not deny him a relationship because the mother kept the child secret; if anything, judges view a mother who concealed a child as having acted against the child’s interests, and that can affect the custody decision.
The child will eventually know. Genetic testing services, family members, and the child’s own questions make long-term secrecy unusual. A mother who kept the pregnancy secret is better off deciding how and when the father learns than having it happen by accident.
When secrecy is about safety
Some mothers keep a pregnancy secret because the father is dangerous. Utah law takes that seriously, and the tools are different. A protective order can prohibit contact and, where the child is at risk, can address custody on a temporary basis. In a paternity case, a history of domestic violence, including coercive control as Utah now defines it, is a custody factor, and supervised parent-time or no parent-time can be ordered. The court can also keep the mother’s address confidential. What safety does not do is eliminate the father’s legal status as a parent; it shapes what that status allows him to do. A mother in this situation should talk to an attorney before the birth so that the protective order and the paternity case are handled together.
What a father who was kept in the dark can do
File a paternity action as soon as you learn of the pregnancy or the child. If the child has not been born, also file the affidavit and the Vital Records notice so an adoption cannot proceed without you. If the child has been adopted, understand that Utah’s one-year limit on challenging an adoption is strict; our article on undoing an adoption explains it. If the child is being raised by the mother, paternity followed by a custody and parent-time order is the path, and the fact that you were not told does not count against you.
The realistic answer
A pregnancy can be kept private. A child cannot. Utah law lets a mother control the pregnancy and, through adoption, the placement, but once she decides to raise the child, both parents’ rights and obligations attach and the father can assert his whenever he finds out. A mother who is weighing secrecy should think about which of those outcomes she actually wants, and get advice on how to reach it cleanly.
CoilLaw handles paternity, custody, adoption, and protective order cases throughout Utah, for mothers and fathers. If you are pregnant and unsure what you owe the father, or a father who has just learned about a child, we can tell you where you stand.
