Parentage: Process to Add or Remove a Father or Second Genetic Parent

According to Oregon law, those wanting to amend a birth record must complete an application, prove their eligibility, and when required, provide evidence documents to support the correction or change to the record. For more information, see ORS 432.098, ORS 432.245, OAR 333-011-0265 and OAR 333-011-0270.
If you need a copy of a current birth certificate, you can order one from our home page. You will be able to exchange one certificate free of charge for an amended certificate within one year of issuance date. Access to a vital record is restricted for a set period after the date of the vital event: 100 years for birth and 50 years for all other records. For these records, applicants must prove they are legally eligible to order certified copies.  

In 2025 Oregon passed Senate Bill 163, which modernizes legal terminology and replaces the term "paternity" with the more inclusive "parentage," reflecting and expanding legal recognition for diverse family structures. The bill stipulates gender-neutral language with expanded parentage definitions.

Throughout this webpage we use the terms “Parent Who Gave Birth" and "Second Genetic Parent. "Second Genetic Parent" includes the non-birth parent regardless of their gender. For more information on the terms used on this web page, you can click the “Definitions" button below. 

Note: the terms “Mother," “Parent A," “Father," or “Parent B" are used on the birth record. Because of this, you may see these terms on different forms or web pages.

​Acknowledgment of Parentage:

    If the parent who gave birth to the child was married or in an Oregon Registered Domestic Partnership during the pregnancy (300 days prior to date of birth) but the second parent currently named on the record is not the parent, by Oregon law the second parent currently named on the record must be disestablished by court judgment before a different parent can be added.


    To prove the second parent currently named on the record is not the parent, please include this document in addition to the items listed in the Checklist to Add or Remove a Second Parent on a Record​​ above:

    • An original, court-certified judgment stating that the parent currently named on the record is not the parent of the child.


    Original, court-certified divorce judgments may also disestablish parentage depending on what is stated in the judgment.


    If acceptable documents to remove the parent currently named on the record and add a different parent ​to the birth record are submitted at the same time, only one amendment fee will be charged.

    ​

    Court judgments can also be submitted that overturn a previous court judgment establishing parentage, or a Voluntary Acknowledgment of Parentage​ form that is found by a court to be in error. Judgments can be accepted from any court in the United States.

      ​

      Oregon hospital staff will make the form available and will witness the parents' signatures. No fee will be charged and the second genetic parent's name will be added to the birth certificate at the hospital. Parents cannot use this form if the parent who gave birth was married or in an Oregon Registered Domestic Partnership at any time during the pregnancy because Oregon law makes a husband the presumed parent​ of the child. 
      ​

      Parents may also sign a notarized version of this form at any time after birth. There is no time limit on signing the form. If the form is not filed at the time of birth, there is a $35 amendment fee for the change to the birth record.


      ​If the parent who gave birth was not married during the pregnancy, both parents may sign and have notarized a Voluntary Acknowledgment of Parentage Affidavit at any time after the child is born and the birth record has been filed.

       

      A $35 fee is charged for filing a Voluntary Acknowledgment of Paternity Affidavit and creating a new birth certificate. F​or more information about the Voluntary Acknowledgment of Parentage Affidavit and instructions for getting a new birth certificate, visit this web page.

      The Oregon Division of Child Support offices and District Attorney offices with child support programs may provide notary public services for this purpose. The Oregon Division of Child Support may also pay the $35 amendment fee if the parents can meet certain requirements. Please see the Division of Child Support web page​ for further information.​
      ​

      ​Affidavits with corrections, white-out, or without notarized signatures for both parents will be rejected. Affidavits will also be rejected if the birth record includes information that the parent who gave birth was married at any time during the pregnancy and no legal documents are submitted proving that the second parent​ has been disestablished.​​

      If the hospital reported that the parent who gave birth was married, the Center for Health Statistics cannot accept and file the Voluntary Acknowledgment of Parentage Affidavit unless the parent who gave birth provides a certified court judgment (such as a divorce decree or a judgment of non-paternity) stating that the person who was the spouse  during the pregnancy is not the genetic or legal second parent of the child. The name of the child and date of birth is needed to match to the birth record. Please send a certified copy of the court judgment (showing the original seal and signature of the court official) with the Voluntary Acknowledgment of Parentage Affidavit.

       

      The language in the court judgment to disestablish the second parent must be specific. It must state that the second parent is not the genetic parent and provide the child's name and date of birth or age. We will use court judgments where there is a finding of the court that there are “no children of the marriage" or “no children of the relationship." Once the second parent is disestablished, the parent who gave birth and a different second parent may sign a Voluntary Acknowledgment of Parentage form.

       

      On the Voluntary Acknowledgment of Parentage form where there is a statement about eligibility to file the form, the parent who gave birth must line out the statement that they are unmarried and initial the change. They should insert a note that previous second parent​ has been disestablished.

      The $35 amendment fee is charged when this process is completed.​


      ​The Division of Child Support or any court may review genetic parentage tests and issue a judgment establishing parentage. The Oregon Center for Health Statistics does not have the legal authority to review parentage reports and change a birth certificate without a legal judgment.

       

      If the parent who gave birth was not married to someone else during the pregnancy and marries the second parent after the child is born, both parents may sign a Voluntary Acknowledgment of Parentage Affidavit. In addition, they may attach a copy of the marriage certificate to the parentage acknowledgment form. When the marriage is verified, the Center for Health Statistics will add the second parent's name to the birth record and change the legal name of the parent who gave​ birth to their legal name after marriage.

      Parentage may be established by a legal judgment from the Division of Child Support  or by a court judgment. If either the second parent or the parent who gave birth will not agree to establish parentage and the child is under the age of 18, either parent may ask the Division of Child Support (DCS) for assistance. DCS may file paperwork that results in a legal judgment to establish parentage and add the second parent's name to the birth certificate.

       

      If the parent who gave birth receives public assistance from any Oregon agency, such as the Department of Human Services or the Oregon Youth Authority, a child support case will be referred to the Division of Child Support automatically. If the parent who gave birth does not receive public assistance, either parent can apply for services with the local county District Attorney.

       

      The Division of Child Support is also responsible for assuring that children are provided with adequate financial support. For information about the child support program, applying for child support, and links to legal assistance agencies, please see the Oregon Division of Child Support Parentage web page​. 

      ​Either parent may obtain a court judgment to establish parentage by hiring an attorney and petitioning a court. If one parent objects, the court may require genetic parentage tests before issuing a​ judgment. The court may also consider other factors including what is in the best interests of the child.

       

      In some cases where the parents marry after the child is born and then divorce, the divorce judgment may state that the former spouse is the second parent of the child and can be used to establish parentage and add a different second parent's name to the birth certificate. The divorce judgment must state explicitly that the former spouse is the genetic parent of the child and the information about the child (name and date of birth) must match the information listed on the birth certificate. A divorce judgment that states that there is "one child of the marriage" without naming the child, or that does not distinguish a genetic child of the marriage from an adopted child, cannot be used to establish parentage. Our office uses a different amendment process for adoption than parentage​ establishment.

       

      The Oregon Center for Health Statistics cannot provide you with legal counsel or documents for petitioning a court and obtaining a court judgment. Please consult an attorney or obtain the assistance of your county district attorney .


      ​The Division of Child Support or any court may review genetic parentage tests and issue a judgment establishing parentage​. The Oregon Center for Health Statistics does not have the legal authority to review parentage reports and change a birth certificate without a legal judgment. ​

      ​If parentage is established after the parent who gave birth leaves the hospital, both parents may agree to change the last name of the child. This surname change must be included on the Voluntary Acknowledgment of Parentage Affidavit forwarded to the Center for Health Statistics. Both parents must agree on the last name. If one parent changes the Voluntary Acknowledgment of Parentage Affidavit by crossing out the last name of the child and writing in a different name, the​ form will not be accepted and a new form must be completed and signed.

       

      After parentage is established and the child is more than one year of age, any change in the last name of the child will usually require a court judgment.​​

      ​No, once parentage has been established and the second parent's name has been added to the birth certificate, the record has legally been changed and the birth record without the second parent's​ name cannot be issued.​

      ​Up to sixty days after filing a Voluntary Acknowledgment of Parentage form or affidavit, either parent named on the record​​ may request that the second parent's name be removed from the birth certificate. To remove the second parent's name, a Rescind or "Take Back" of Parentage Acknowledgment form must be filed with the Center for Health Statistics within sixty days. Parents may call 971-673-1147 or email CHS.Amendments@oha.oregon.gov and ask for the "Rescind of Voluntary Acknowledgment". There is no fee for filing this form.

       

      Up to one year after filing a Voluntary Acknowledgment of Parentage form or affidavit, either parent can request parentage testing. Parentage established by either the Division of Child Support (DCS) or the District Attorney (DA) can also be reopened in the first year by requesting parentage tests if they were not done before. Please contact your local DCS or DA office for additional information.

       

      Once testing is completed, a court judgment may be issued to either remove or change the second parent listed on the birth certificate. The Center for Health Statistics will need a certified copy of the court judgment (showing the original stamp and signature of the court official), and a fee of $60. The fee includes the cost of a new certified copy of the updated birth certificate. Parents who petition a court directly need to obtain a certified copy of the court judgment. In cases where the Division of Child Support  follows up by completing the parentage tests, DCS may send a certified copy of the court judgment to our office to change the name of the second parent on the birth certificate.

       

      After a full year from the date parentage was established, either parent challenging the name of the second parent on a birth record must petition a court and obtain a court judgment to either remove or change the second parent​ listed on the birth record. Again, the Center for Health Statistics needs a certified copy of the court judgment with the original stamp and seal of the court and the $35 fee for changing the birth certificate.​

      ​When parents sign a Voluntary Acknowledgment of Parentage form or affidavit, the hospital staff or vital records office receiving the form should provide both parents with a copy. The Voluntary Acknowledgment of Parentage form includes a carbon copy for both the parent who gave birth​ and the second parent.

       

      Once the Voluntary Acknowledgment of Parentage form or affidavit is filed with the Center for Health Statistics, it is placed in a special sealed file and access is restricted. Per House Bill 2093 and administrative rules effective January 1, 2014, parents listed on the birth record and the registrant named on the record after age 18 may request a copy of the Voluntary Acknowledgment of Parentage form.

       

      It may also be requested by a child support agency created under Title IV-D of the Social Security Act. Any other person or agency requesting a copy of the document must petition an Oregon court to obtain a court judgment for the release of the form. If such a judgment is obtained, you may forward a certified copy of the court judgment (showing the original seal and signature of the court official). The fees are $24 fee for a certified copy of the Voluntary Acknowledgment of Parentage, or $4 for an uncertified copy. To order, please see our Oregon Parentage​ Affidavit Order Form.


      ​Oregon law (ORS 432.350 ) restricts access to birth records and information to immediate family members and their legal representatives. To receive a birth record, you must be listed on the child's birth certificate. To find out whether you are listed as the second parent, you must order a copy of the record and provide the child's name, date of birth, place of birth (city and county), full name before any marriages (maiden name) of the parent who gave birth to the child, and your full name as the second genetic parent. The non-refundable fee for a record search is $25.

       

      The Center for Health Statistics will search for the record and you will receive one of the following:

      • A certified copy of the birth certificate if you are listed as the father or second​ parent.

      • A statement that you are not eligible to receive the record because no father or second parent is listed on the birth record. If the parent who gave birth was not married at any time during the pregnancy, a Voluntary Acknowledgment of Parentage Affidavit will also be enclosed for use by the parents. When submitting the Acknowledgment affidavit with the $35 amendment fee, please include a copy of the order form showing proof of payment of the $25 certificate fee. You will then be charged the $35 amendment fee, but not an additional certificate fee.

      • A statement that you are not eligible to order the record. This statement will be sent if the record is found but someone else is listed as the father or second parent on the birth record.

      • A statement that no record can be found. If you receive this response, either the information provided was not accurate enough to locate the birth record, or the child was adopted and is now listed under a new adoptive name and new adoptive parents.​
