Can a Child Be Adopted Without the Father's Consent?
By Isaac Thomas, LCSW · Chief Executive Officer

This is one of the first questions many expectant mothers ask, and one of the most misunderstood. The short answer is that in many situations an adoption can go forward without the birth father's consent, but whether yours can depends on three things: the state involved, whether you and he were married, and whether he has done what the law requires to claim his rights. Nothing here is legal advice for your specific case. It's a map, so the conversation with your attorney makes sense.
The Three Questions That Decide It
- Were you married to him? A husband is generally presumed to be the legal father, and his consent (or a court order ending his rights) is usually required. Unmarried fathers have to establish their rights first.
- Has he taken the legal steps his state requires? Most states give an unmarried father a window to assert paternity, often through a putative father registry and a court filing. If he does nothing within that window, his consent is generally not required.
- Has he supported you or the pregnancy? Many states also look at whether he has shown commitment, such as financial or emotional support during the pregnancy, when deciding whether his consent is needed.
How It Works in Utah
Utah has one of the clearest frameworks in the country. An unmarried biological father who wants a say in an adoption must act before the birth mother signs her consent: file with Utah's putative father registry, start a paternity action, and file the sworn statements the law requires, including a commitment to take custody and pay support. If he has not completed those steps when the mother's consent is signed, his consent to the adoption is generally not required and he typically cannot contest it later.
The timelines are strict, and the details matter, which is exactly why every birth mother working with us has her own independent attorney, at no cost to her. Your attorney handles the notice requirements and the registry check. You do not have to figure any of this out yourself, and you do not have to contact him if you don't want to.
The adoption follows the rules of the state where it is finalized, and interstate placements also go through the ICPC process. Your attorney confirms which state's father's-rights rules apply before anything is signed.
What If I Don't Know Who the Father Is?
This is more common than you might think, and it has a clear legal path. The attorney documents what is known, checks the putative father registry, and follows the state's notice process. An unknown father does not stop an adoption from moving forward.
What If He's Against It, or I'm Afraid of Him?
Being against adoption is not the same as having the legal right to stop it. If he has not taken the steps his state requires, his objection alone usually does not block the adoption. If there are safety concerns, say so on the first call. Your information stays confidential, legal notice can be handled without you contacting him, and your counselor and attorney plan around your safety first.
What If He's Supportive?
Then it's simpler. A supportive birth father can take part in choosing the family, be part of the hospital plan if you want him there, and sign his own consent. Many of the families in our program have ongoing contact with both birth parents.
A Note for Stepparents and Relatives
If you're asking because a husband or relative wants to adopt a child who already lives with you, the rules are different. Those adoptions generally require the biological father's consent or a court order terminating his rights, typically on grounds such as abandonment or failure to support. A family law attorney in your state can tell you where you stand. Our agency focuses on infant adoption, so we're not the right resource for stepparent cases, but the general framework above still applies.

Frequently Asked Questions
Can a mother give a baby up for adoption without the father's consent?
Often, yes. If she was not married to him and he has not taken the legal steps his state requires, such as registering with a putative father registry and filing a paternity action within the deadline, his consent is generally not required. The rules vary by state, so an attorney reviews each case.
Does the birth father have to be notified?
Usually some form of legal notice is required when the father is known, and the attorney handles it. In many states the birth mother does not have to contact him herself, and if there are safety concerns the process is planned around that.
What is a putative father registry?
A state registry where an unmarried man can record that he may be the father of a child, to receive notice of an adoption. In Utah, filing with the registry is one of several steps a father must complete before the mother's consent is signed to preserve his rights.
Can the father stop the adoption after the baby is born?
Only if he has preserved his rights under his state's rules. In Utah, a father who has not completed the required steps by the time the mother's consent is signed generally cannot contest the adoption afterward.
Can my husband adopt my child without the biological father's consent?
Stepparent adoptions generally need the biological father's consent or a court order terminating his rights, usually on grounds like abandonment or failure to support. A family law attorney in your state can advise on your situation.
Do I have to pay for the attorney?
No. Birth mothers working with us receive independent legal counsel at no cost, and the attorney represents only you.
