Original Birth Certificates. Kansas is an Unrestricted State. Kansas-born adult adopted people have always had an unrestricted right to obtain their own original birth certificates upon request. The Kansas Department of Public health requires a notarized letter to request the record, and the cost is $20.00.
Court Records. Court records are sealed and unavailable except to the parties in interest and their attorneys or upon release by court order. A party in interest does not include birthparents and generally does not include the adopted person.
Identifying Information. Kansas law does not directly address the release of identifying information other than through release of the adopted person’s own original birth certificate. Birthparents and adult adopted people, however, may seek information and contact through the Kansas Department for Children and Families, which acts as an intermediary in such cases.
Descendant Rights. Descendants of a Kansas-born adopted person do not have a specific right to request the adopted person’s original birth record. A court order is required, though if the adoptee is deceased it is likely granted.
Adult Adoption. Kansas law provides for the adoption of adults. Consent of the person being adopted is required, and notice to the adoptee’s current parents may be required. If notice is not given to the prior parents, a copy of the adoption decree must be sent to the former parents.

Lisa Barron says
I don’t think you can help me since you practice law in Minnesota, I will give this a try anyway. I wanted to Vacation/Annul my adoption in order to get a copy or reinstate my deceased Birth parents listed back on my birth certificate and remove my deceased adopted parents. I wanted to get my original birth certificate back since I took my birth name back after my divorce. I was born and raised in Kansas and adopted in my teens when I did not agree to it. My birth dad gave permission to his sister and husband to change my last name in order to keep my birth mother away in their bitter divorce. I live in Pennsylvania now and I’m running into road blocks saying I cannot obtain my original birth certificate with my birth parents listed.
Gregory D. Luce says
Your birth and adoption was in Kansas? While Kansas seals a birth certificate when a new one is issued after adoption, the original is always available to the adoptee once he or she turns 18. But am I hearing that you want your original reinstated as the only birth certificate? It’s a tough legal fight to annul an adoption in any state, and it’s a legal avenue that will take a lawyer to figure out what’s best to do so in Kansas. One alternative could be a name change to your original name.
Rachida Djebel (née Averill) says
Good morning Greg.
First I must tell you that I love this site for its clarity and citing of state’s’ law concerning adoptees. You have done and are doing a grand service to the adoptee in search.
In professional life I am a regulatory consultant so am used to almost any regulation known to mankind… almost. I understand that Kansas is ‘unrestricted’ regarding an adoptee’s access to his/her own adoptee adoption file and OBC—which is terrific! However wonderful that may be, there are cases when the adoptee has died and his/her child(ren) wish to have the un-redacted certificate, not the amended one.
In private life I try to help adoptees obtain documents and give them ways to do that. Your site is a huge asset! Currently I have a friend who is the daughter of an adoptee born in Kansas who is deceased. The deceased was adopted in Missouri. She has applied to KS for the birth certificate of her mom-who for years did not know of KS open access for adoptees, but receives only the redacted/amended version rather than the original, leading me to believe that KS & MO must have some agreement and share amended/redacted certificates … Of course I could very well be wrong.
My knowledge based on being an adoptee who retrieved her own OBC despite the draconian Dickensian laws of Nebraska is that where there is a will, there is a way. (My case was complicated in that I was not born in NE and was not aware of that fact until I applied for a US passport and was refused, which spurred my determination to find that OBC… and I did!)
My thoughts are that a petition to the court by the daughter might produce the desired results, with of course adequate documentation to prove relationship. I know that in the case of the adoption file she would most likely fall under the category of ‘person of interest’.
What would be your counsel? I, and my friend, would very much appreciate any nuggets of wisdom you may have for us. She wants to keep the promise she made to her mother I and I want to help her fulfill that promise.
Thank you in advance for your assistance with this matter.
Gregory D. Luce says
Thanks so much, Rachida, for the comments.
And, yes, you are spot on: your friend would need to petition the court in Kansas for release of her mother’s OBC. I’ve been approached by a number of descendants of adoptees whose parents were born in Kansas. The courts have told them that a petition is necessary. I tell folks to contact the court in the county where the person was born and ask if they have procedures for petitioning the court for the records, if any, and for an order to release the OBC. Given the fact that Kansas is an unrestricted state for the adult adoptee, I’d be surprised if the OBC is not released by court order to the adult son or daughter of the adoptee, so long—as you say—the relationship to the adoptee is shown and that you also provide a death certificate showing that the adoptee is deceased. It probably would not hurt to provide a copy of the amended certificate of the adoptee in the filing just to provide the full picture. I have very generic and simple forms I use here in Minnesota that you could likely use as a template if that’s worthwhile. Feel free to contact me by email at [email protected].
If you pursue this, I’d love to know what you find out and what the court may decide or tells your friend what to do. Good luck and thanks for your advocacy and for your obvious perseverance.
Rachida Djebel (née Averill) says
Thank yo so very much for confirming that I am on the right path and for the offer of reviewing your template for petitioning the court which I have sent an email for. I have advised my friend we will need her mother’s death certificate, her birth certificate (to prove relationship) and the amended birth certificate. I’ve also advise her to contact the county court of adoption for advice regarding the petition.
I will indeed keep you advised as to how this plays out.. I am a believer in sharing information and experience…. all we who are adopted—whether domestic or international—are pretty much in the same boat.. often that is often too rocky and sea-sickness producing.
I fought for my own rights for over 50 decades.. and will continue to do what I can for our cause.
Gregory D. Luce says
No problem. And, by the way, love the typo of 50 decades. It does feel like 500 years sometimes. 🙂
Rachida Djebel (née Averill) says
It was indeed a typo.. how about five? And actually now into 7 as I am still pushing for access to my sister… who is if alive 71 this year and I am 73 in the first week of April 🙂 sometimes it feels like a million years.. but I persist…
Korissa Thomas says
hello, hoping maybe you can help me shed some light on all of the discrepencies that I’ve discovered during my adoption records search. Kansas recently updated their laws about drivers licensing and therefore were required to show an original birth certificate with the state seal on it. Copies will not be accepted. For adoptees, we need our original PLUS the amended, proving that we were adopted and are now living by this name. No big deal, right? Wrong. I am 30 years old and just found out that not only was my adoption not legal in the state I was born in…. but my name isnt even correct. Oh, not to mention the fact that my birth state thinks I’m a missing person (Im not, for the record… just some slacker misfiling paperwork years ago…. clearly because HIS life wasn’t being questioned. *sigh*)
and Kansas (my adopted state) is being so cryptic with me…. Get this…
The copies I have of the adoption (which are old tattered pages that don’t look legit but supposedly they are)… are literally the only documents that exist. Court Clerk informed me that the microfilm and all records of my adoption were destroyed in a natural disaster…. which isnt possible because we havent had a disaster that would come even close to record ruining…. so I tracked down the attorney that handled my adoption 30 years ago… by a stroke of luck he was still practicing… so I sat down with him… he was extremely uptight and vague with every answer. Kept telling me that he doesnt remember that far back… but even if he did, he isnt able to give me the answers to my questions. Funny, because he recalled a few insignificant minor details that nobody would have any business remembering unless there was something BIGGER behind it all…. OH YEAH, and did I mention that my birth father was never notified of my adoption or even my existence, even though my adoption papers state that he was notified via publication? Lie. There was no publication made anywhere in the US, lawyer verified that. I dont know, but as of right now, the name Ive used for 30 years is suddenly an “alias,” all my records vanished into thin air, Tennessee thinks I am a missing child, my adopted dad is so confused and angry because he knows this is all a huge screw up, technically… I was never adopted, I vanished into thin air, and I legally do not exist…. my dad is helping me fight just to be able to exist once again. heeelllppppp
Jessica M says
I was adopted at birth in Kansas. The adoption was arranged prior to my birth. I want to request my original birth certificate. I know who my birth mother and have had contact with her over the last 13 years. She however will not tell me who my birth father is (if she even knows).
I was born in 1983 so my question pretty much is if she would have been required to put a Father’s name down on my original birth certificate. I have the information I need to request the original but I assume if she won’t tell me who he is I doubt she would put it on the original birth certificate unless she legally had to do it.
All I’m after really is family medical history for my son’s benefit in the future as I am more than happy with the family I was given and don’t want or need anything from anyone.
If you would know any information on this it would be greatly appreciated!
Kalyn Fuller says
I was adopted at newborn and I don’t know my birth mothers name and my dad’s name was not on the birth certificate And I am trying to get my birth certificate before I was adopted I was born in 1980 in Barton County the birth records were sealed cause it was a private adoption and I want my birth certificate before adoption for my health history cause I have seizures that have caused me to be on disability and I also want them for my 14 years old daughter so she can know her health history all I know about my birth mom is that she was 13 when she had me she was catholic and native American and my mom that adopted me said that I am 25 percent native American but wouldn’t tell me anything else and this is very important to me I want to know what I have to do to get it
Ashley Tokoi says
I have a child living with me whose mom died and she was adopted by a less than ideal step parent. She has filed for emancipation but would like her BC amended to remove said step parent and return her mom back to the document. Is this possible?
Gregory D. Luce says
Yes, it’s possible, but it can be very complicated. There are generally two ways to do this: 1) you can get the agreement of the adoptive parent to annul or vacate the adoption and restore the original birth certificate; or 2) seek a court order that would amend or restore the birth certificate back to its original but it would not otherwise change the adoption or vacate it. Both would require court involvement, and typically it would be in the county where the adoption occurred.
It’s a complicated process, primarily because there is very little law to guide attorneys and the court. Because of this, it’s impossible to predict if these efforts would be successful.
