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

The idea of marrying one’s cousin evokes a range of reactions, from curiosity to disapproval. While cousin marriage has deep roots in many cultures throughout history, its acceptance varies widely in the modern world. In the United States, the legality of such unions is determined at the state level, creating a patchwork of regulations that can be confusing to navigate. This article delves into Pennsylvania’s laws regarding cousin marriage and explores the complex arguments surrounding this controversial topic.

Legality of Cousin Marriage in the United States

The United States presents a mixed landscape when it comes to the legality of cousin marriage. Currently, roughly half of all US states legally permit marriage between first cousins. Several other states allow it with certain restrictions, such as requirements for genetic counseling, age limits, or proof that one or both parties are infertile. The remaining states, including Pennsylvania, explicitly prohibit marriage between first cousins.

Pennsylvania’s Stance on Cousin Marriage

Pennsylvania law is unambiguous in its ban on first-cousin marriages. The relevant statute, Title 23 (Domestic Relations) of the Pennsylvania Consolidated Statutes, Section 1303, states: “No person shall marry … a first cousin.” Breaking this law could result in the marriage being considered void and potentially carry additional legal consequences.

Reasons Behind the Cousin Marriage Ban

  • Genetic Concerns: The primary argument against cousin marriage stems from the increased risk of birth defects and genetic disorders in offspring born to closely related parents. First cousins share around 12.5% of their DNA, meaning there’s a greater chance of both carrying recessive genes for the same diseases. Studies have shown that children from such unions have a slightly elevated risk of conditions like cystic fibrosis, sickle cell anemia, and intellectual disabilities.
  • Societal and Moral Arguments: Beyond the scientific concerns, societal and moral objections to cousin marriage also exist. Some view it as violating traditional family roles or religious doctrine. Others worry about potential power imbalances or exploitation within families where cousin marriage is practiced.

Arguments in Favor of Cousin Marriage

  • Personal Liberty: Advocates for the legalization of cousin marriage argue that consenting adults should have the fundamental right to marry the person they love, regardless of familial ties. They believe that government bans on cousin marriage are an unnecessary intrusion into personal lives.
  • Cultural Practices: It’s important to acknowledge that cousin marriage is a long-standing tradition in certain cultures and religions around the world. In some communities, these marriages are seen as strengthening family bonds and preserving cultural heritage.

The Debate Over Cousin Marriage

  • Shifting Perspectives: Public opinion on cousin marriage is gradually evolving. Though it remains taboo in many Western societies, there’s growing support for relaxing bans. Conversely, some advocates seek even stricter regulations, aiming to ban marriages between more distant relatives.
  • The Role of Science: Advances in genetic testing and counseling have the potential to reshape this debate. Pre-marriage genetic screening can help couples understand the risks associated with their union and make informed reproductive decisions.

Practical Considerations If Considering Cousin Marriage

  • Legal Implications: Pennsylvania residents who wish to marry their first cousin must travel to a state where such marriages are legal. It’s crucial to understand that the validity of the marriage might be contested if the couple returns to Pennsylvania.
  • Genetic Counseling: Any couple considering cousin marriage is strongly advised to seek comprehensive genetic counseling. A qualified genetic counselor can assess their specific risk factors and provide guidance on family planning.
  • Potential Social Stigma: Sadly, couples may encounter negative judgment or social ostracism based on their decision to marry their cousin. It’s essential to be prepared for this possibility.
