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

The concept of marriage between cousins evokes varying reactions across the world. Historically, cousin marriage has been widely practiced in many cultures for reasons of maintaining social structures, preserving wealth, and strengthening family ties. However, modern perspectives on cousin marriage are marked by debates surrounding genetic risks, ethics, and individual freedoms. In the United States, the legality of cousin marriage varies from state to state. This article will delve into the specific case of Delaware, exploring its laws on cousin marriage and the reasoning behind them.

Delaware’s Laws on Cousin Marriage

Delaware law explicitly prohibits marriage between first cousins. The relevant statute, found in Title 13 of the Delaware Code, Section 101 (a), states: “A marriage may not be contracted between persons who are related to each other as… first cousins.” This means that individuals who share a set of grandparents are legally barred from marrying in the state of Delaware.

While the exact historical origins of this prohibition might require deeper research, such restrictions mirror broader trends in Western legislation aiming to manage potential health-related consequences of close familial unions.

Reasons Behind Restrictions on Cousin Marriage

  • Genetic Concerns: The primary argument against cousin marriage centers on the increased risk of birth defects and recessive genetic disorders in offspring. First cousins share approximately 12.5% of their genes, raising the probability that both parents may carry recessive genes for the same disorder. Children born from such unions have a higher chance of inheriting two copies of the recessive gene, leading to conditions like cystic fibrosis, sickle cell anemia, and certain types of intellectual disabilities.
  • Social and Ethical Arguments: Beyond the medical concerns, some opponents of cousin marriage raise social and ethical objections. They might argue that it disrupts traditional family structures or can be viewed as blurring the lines between family and romantic relationships.

Arguments in Support of Cousin Marriage

  • Personal Liberty: Advocates for cousin marriage often frame the issue as one of personal liberty and the right of consenting adults to choose their partners. They argue that the government should not interfere in matters of personal choice and that restrictions on cousin marriage infringe upon fundamental freedoms.
  • Cultural and Religious Traditions: In some cultures and religions, cousin marriage is not only accepted but preferred. These communities may see such marriages as a way of strengthening family bonds, preserving traditions, and ensuring the socioeconomic well-being of families.

The Prevalence of Cousin Marriage

  • United States: In the United States, cousin marriage is relatively uncommon, though the exact rates are difficult to measure. It is estimated that about 0.2% of all marriages are between first cousins. Laws regarding cousin marriage vary significantly from state to state. Currently, roughly half of US states ban first-cousin marriages, some permit them, and others allow them with conditions like genetic counseling or age requirements.

The Prevalence of Cousin Marriage

  • Global Trends: Worldwide, cousin marriage is a far more common practice. It is particularly prevalent in regions such as the Middle East, North Africa, and parts of South Asia, where rates of cousin marriage can exceed 50% in some countries.

Alternatives to First-Cousin Marriage

  • More Distant Relatives: While Delaware prohibits first-cousin marriage, the law may permit marriage between more distant cousins (like second cousins). Second cousins share approximately 3% of their genes, significantly reducing the genetic risks associated with first-cousin unions.
  • Alternatives to Marriage: Some couples facing prohibitions on first-cousin marriage might explore alternative forms of committed relationships that do not involve legal marriage. This could include domestic partnerships, civil unions, or other forms of non-marital agreements that provide structure and commitment within their relationship.

In the state of Delaware, it is illegal for first cousins to marry. The law, driven by concerns over health risks to potential offspring and a range of ethical considerations, reflects a broader pattern within the United States where the legality of cousin marriage is contested. While proponents argue for personal choice and the safeguarding of cultural traditions, opponents highlight the potential medical and social implications.

Ultimately, the debate surrounding cousin marriage is complex and multifaceted. Whether Delaware’s laws will eventually shift remains to be seen, with the conversation likely to be influenced by evolving scientific knowledge, changing societal perspectives, and ongoing legal challenges about the right to marry.
