Is It Illegal to Marry Your Cousin in Nebraska? Here’s What the Law Says

The concept of marrying a cousin may seem unusual or even taboo in some cultures. However, cousin marriage has a long history across the globe and remains practiced in various parts of the world. In the United States, the legality of marrying your first cousin varies from state to state. So, what does the law say about cousin marriage in Nebraska?

Nebraska Law on Cousin Marriage

Nebraska is one of the states in the US that explicitly prohibits marriage between first cousins. Nebraska Revised Statute Section 42-103 states:

“No marriage shall be contracted while either party has a spouse living, nor between parties who are nearer of kin than first cousins, whether of the whole or half-blood, computing by the rules of the civil law, except that when parties are first cousins and the female is older than fifty-five (55) years of age, they may marry. It shall not be lawful for any person to marry his or her father, mother, child, grandchild, brother, sister, brother’s son, sister’s son, brother’s daughter, sister’s daughter, father’s brother, mother’s brother, father’s sister, or mother’s sister.”

This law effectively means that if you and your partner share a grandparent (meaning you are first cousins), you cannot legally marry in the state of Nebraska.

Historical and Cultural Context of Cousin Marriage

  • Global Perspective: Cousin marriage has been practiced for centuries in many cultures worldwide, often for social, economic, and familial reasons such as maintaining family ties, consolidating wealth, and ensuring cultural continuity.
  • American History: While less common now, cousin marriages were historically more prevalent in the United States, particularly in rural communities. Noted figures like Charles Darwin and Edgar Allan Poe married their first cousins.

Scientific and Genetic Considerations

  • Increased Risk of Recessive Disorders: Children born from parents who are closely related have a higher chance of inheriting recessive genetic disorders. This is because closely-related individuals are more likely to carry the same recessive genes. While the risk increase is relatively small for first cousins, it can become progressively more significant with closer biological relationships.
  • Research: Studies on the offspring of first-cousin marriages indicate a slightly elevated risk of birth defects and genetic disorders, roughly comparable to the risks faced by a woman who gives birth in her early forties.

Arguments For and Against Cousin Marriage

Arguments in Favor

  • Personal Liberty: Some people believe that laws prohibiting cousin marriage infringe on individual freedom and the right to choose one’s spouse.
  • Cultural Tradition: In cultures where cousin marriage is accepted, it’s seen as a means of strengthening family bonds and preserving traditions.
  • Familial Compatibility: Advocates may argue that cousins often know each other well and may have compatible personalities and values.

Arguments Against

  • Genetic Risks: The primary argument against cousin marriage centers around the increased likelihood of recessive genetic disorders in offspring.
  • Social Stigma: In some societies, cousin marriage may carry a negative social stigma.
  • Ethical Concerns: Some individuals raise ethical concerns about the potential for power imbalances or pressure within families that could lead to cousin marriages.

Public Opinion on Cousin Marriage in Nebraska

Unfortunately, there isn’t extensive recent data on public opinion regarding cousin marriage specifically within Nebraska. However, some broader insights can be drawn:

  • Residency in Another State: If marriage is a priority, the couple could establish residency in a state where cousin marriage is legal. It’s important to research the specific laws and residency requirements of the chosen state.
  • Advocacy: Individuals who feel strongly about the right to marry their cousin might consider engaging in advocacy efforts to change Nebraska law. This could involve contacting state representatives or joining organizations that support changes in marriage laws.

The Evolving Debate

The legality and social acceptance of cousin marriage are part of an ongoing debate influenced by factors like cultural shifts, scientific understanding, and individual rights arguments. Here are some points to keep in mind:

  • Medical Advances: Progress in genetic screening and counseling may offer couples more comprehensive information about risks, potentially influencing future attitudes towards cousin marriage.
