How to Complete Kansas Form VS211: Signing, Notarizing, and Revoking

Kansas Form VS211 is the state’s voluntary paternity acknowledgment, a notarized form that unmarried parents sign to legally establish the father-child relationship without going to court. Both the biological mother and the man claiming to be the father sign it, and once the Kansas Office of Vital Statistics files it, it carries the same legal weight as a court paternity finding. The father’s name goes on the birth certificate, and both parents pick up permanent rights and obligations around custody, support, and inheritance.

Who Can Sign the Form

Only two people sign VS211: the child’s biological mother and the man who says he is the biological father. Both must sign voluntarily, and each has the right to consult an attorney first.¹

There’s one situation where the form doesn’t work. If the mother was married at the time of birth, or within 300 days before it, Kansas law presumes her husband is the legal father.² That presumption blocks VS211. Naming a different man as the father in that situation requires a court order first; the voluntary form alone won’t override the presumption.

Where to Get the Form

Most parents complete VS211 at the hospital right after the birth. Kansas runs a hospital-based voluntary acknowledgment program, so birthing staff offer the form to unmarried parents as part of birth registration. If you leave without signing it, you can download the form from the Kansas Department of Health and Environment website.³ You can also request a copy from the Office of Vital Statistics at 785-296-1400.⁴

Information You Need Before You Sign

Have this ready:

For both parents: full legal name, Social Security number, date of birth, current residential address, and state of birth.
For the child: full name, date of birth, and the name and location of the hospital or birth facility.
Government-issued photo ID for both parents, which the notary will check.

Get the details right the first time. The information on VS211 goes straight onto the child’s official birth certificate, and correcting a mistake later means an amendment process or a court order.

Notarization

Both parents must sign in front of a notary public or another authorized witnessing official. The notary verifies each signer’s identity with photo ID, administers the oath, and applies the seal. Without proper notarization the form will not be accepted.

At the hospital, staff usually have a notary or authorized witness on hand. If you sign later, you’ll need to find your own notary. Banks, courthouses, and shipping stores commonly offer the service.

Where to Send the Completed Form

Mail the signed, notarized original to:

Office of Vital Statistics
Curtis State Office Building
1000 SW Jackson Street, Suite 120
Topeka, KS 66612-2221⁵

Use certified mail or another trackable method. The form contains Social Security numbers and other sensitive information for two adults and a child.

What Happens After You File

Staff at the Office of Vital Statistics review the form for completeness and verify the notary seal. If everything checks out, the father’s name is added to the child’s permanent birth record. You can then order certified copies of the updated birth certificate for $20 each.⁵ To check on a submission, call the Office of Vital Statistics at 785-296-1400.⁴

What You Are Agreeing To

Signing VS211 creates a permanent legal parent-child relationship. The consequences are easy to underestimate in the moment.

Custody and Parenting Time

Once paternity is established under Kansas law, both parents automatically have rights to custody and parenting time. No separate court petition is needed to create those rights.¹ If the parents can’t agree on where the child lives or how time is divided, a court order is the only way to enforce a specific arrangement. Both parents also gain the right to consent to medical treatment for the child unless a court says otherwise.

Child Support

Both parents become legally responsible for the child’s financial support the moment VS211 is filed. If support isn’t provided voluntarily, either parent, or the state, can pursue a court-ordered obligation. Kansas treats willful failure to support your child as a criminal offense.¹

Inheritance and Benefits

The child gains the right to inherit from the father and the father’s family the same way a child born during marriage would. That includes public benefits like Social Security survivor or disability payments and private benefits such as life insurance and workers’ compensation. Either parent may also claim the child as a dependent for tax purposes.¹

How to Revoke the Acknowledgment

Kansas law provides two revocation tracks with different timelines and different burdens of proof. The details matter.

Within 60 Days of Signing

If you act within 60 days after signing, or before the date of any court proceeding involving the child (whichever comes first), you can revoke VS211 without having to prove anything went wrong. No fraud, no duress, no mistake required. Once the window closes, this no-questions-asked option disappears.⁶

After 60 Days but Within One Year of Birth

You can still bring a court action to revoke at any time until one year after the child’s date of birth. The difference is that you carry the burden of proving the acknowledgment was based on fraud, duress, or a material mistake of fact, such as DNA results showing the man who signed is not the biological father. Legal obligations, including any child support, remain in effect during a revocation proceeding unless the court specifically suspends them for good cause.⁶

If You Were Under 18 When You Signed

A parent who signed as a minor gets an extended timeline: they can file to revoke up to one year after turning 18. If the child is older than one at that point, the court weighs whether revocation is in the child’s best interest before allowing it.⁶

After one year from the child’s birth, or one year after a minor parent turns 18, the acknowledgment becomes a permanent legal determination of paternity. From that point on, it can only be ended by a court order, and the standard for overturning it is significantly higher.¹
