How to Establish Paternity in Minnesota
Reviewed by DocDraft Legal Team · Minnesota · Last updated 2026-09-12
In Minnesota, establishing paternity means legally identifying a child's father so the child gains rights to support, custody and parenting time, health coverage, inheritance, and benefits. Unmarried parents who agree can sign a Recognition of Parentage, which once signed and filed has the same legal effect as a court order (Minn. Stat. 257.75). When parents do not agree, a court action decides parentage under Chapter 257. Minnesota's load-bearing timing rule turns on whether the child has a presumed father. For a child with no presumed father, an action to establish the father-child relationship is not barred until one year after the child reaches the age of majority, so it may be brought up to the child's nineteenth birthday (Minn. Stat. 257.58). A man is presumed to be the father when married to the mother and the child is born during the marriage or within 280 days after it ends (Minn. Stat. 257.55). An action to declare the nonexistence of that presumed relationship must be brought within two years after the person has reason to believe the presumed father is not the father, and in no event later than three years after the child's birth (Minn. Stat. 257.57). Genetic tests showing a likelihood of paternity of 99 percent or greater create an evidentiary presumption (Minn. Stat. 257.62). Under federal law, either parent may rescind a Recognition within 60 days. Attorney review of your situation is available through DocDraft.

What are my options for establishing paternity in Minnesota?
There are two routes. Unmarried parents who agree can sign a Recognition of Parentage, which once filed has the same effect as a court order (Minn. Stat. 257.75). If parents disagree, a court action determines parentage under Chapter 257 and the court can order genetic testing before deciding.
How long do I have to establish paternity in Minnesota?
For a child who has no presumed father, an action to establish the father-child relationship is not barred until one year after the child reaches the age of majority, which in Minnesota means the action can be brought up to the child's nineteenth birthday (Minn. Stat. 257.58).
What is the marital presumption of paternity in Minnesota?
Under Minn. Stat. 257.55, a man is presumed to be the father if he and the mother are or were married and the child is born during the marriage or within 280 days after it is terminated by death, annulment, dissolution, or divorce. The presumption may be rebutted by clear and convincing evidence.
What genetic-testing result establishes paternity in Minnesota?
Under Minn. Stat. 257.62, if blood or genetic tests show a likelihood of the alleged father's paternity of 99 percent or greater, calculated with a prior probability of no more than 0.5, there is an evidentiary presumption of paternity, and the opposing party must disprove it by clear and convincing evidence.
Minnesota paternity law at a glance
Minnesota places paternity under Chapter 257. Unmarried parents who agree can establish parentage without court by signing a Recognition of Parentage, which once signed and filed has the same legal effect as a court order (Minn. Stat. 257.75). The defining Minnesota timing rules turn on the presumed-father question. For a child with no presumed father, an action to establish the father-child relationship is not barred until one year after the child reaches the age of majority, so it may be brought up to the nineteenth birthday (Minn. Stat. 257.58). When the child was born during a marriage, the husband is a presumed father (Minn. Stat. 257.55), and a challenge must be brought no later than three years after the child's birth (Minn. Stat. 257.57). Genetic tests showing a likelihood of paternity of 99 percent or greater create an evidentiary presumption (Minn. Stat. 257.62).
Establishing Minnesota paternity for a child born to unmarried parents
Suppose a child is born in Minnesota to unmarried parents who agree on the father. At the hospital both sign a Recognition of Parentage, which once filed has the same legal effect as a court order (Minn. Stat. 257.75). Weeks later one parent has second thoughts and can still rescind within 60 days of signing under the federal rule that applies in Minnesota. Had the parents disputed parentage, either could file an action under Chapter 257; because this child had no presumed father, the action would not be barred until the child's nineteenth birthday (Minn. Stat. 257.58). The court could order genetic testing, where a likelihood of 99 percent or greater creates an evidentiary presumption (Minn. Stat. 257.62). Had the child been born during a marriage, a challenge to the husband's paternity would have to come within three years of birth (Minn. Stat. 257.57). Attorney review is available through DocDraft.

Suggested Compliance Checklist
Determine whether the child has a presumed father
Before signing or filing anything days after startingDetermine whether the mother was married and the child was born during the marriage or within 280 days after it ended, which makes the husband a presumed father (Minn. Stat. 257.55) and triggers the short three-year challenge deadline (Minn. Stat. 257.57).
Get genetic testing if biological parentage is uncertain
Before signing a Recognition days after startingBecause a Recognition carries the force of a court order, obtain genetic testing first if there is any doubt. Under Minn. Stat. 257.62, a likelihood of paternity of 99 percent or greater creates an evidentiary presumption of paternity.
Sign and file the Recognition of Parentage
At the hospital or through vital records days after startingUnmarried parents who agree sign the Recognition of Parentage and file it with the Office of Vital Records, giving it the same effect as a court order (Minn. Stat. 257.75). Keep a copy. Attorney review of your paternity matter is available through DocDraft.
Track the federal 60-day rescission window
Within 60 days of signing days after startingIf you need to cancel a signed Recognition, rescind within 60 days of signing under the federal rule that applies in Minnesota. After 60 days it can be challenged only on the basis of fraud, duress, or a material mistake of fact.
File a parentage action before the deadline if parents disagree
Before the applicable limitation days after startingIf parents do not agree, file under Chapter 257. For a child with no presumed father the action is not barred until the nineteenth birthday (Minn. Stat. 257.58); a challenge to a presumed father must come no later than three years after birth (Minn. Stat. 257.57).
Keep records of the Recognition, testing, and orders
Ongoing days after startingSave copies of the signed Recognition, genetic-test results, and court papers, and calendar the applicable limitation and the federal 60-day window so you do not miss a right-forfeiting date.
