Can First Cousins Marry In Connecticut? (Explained)

This article looks in-depth at aspects of cousin marriage in the state.

What You Should Know About First Cousin Marriage In Connecticut

Connecticut requires that you apply for a marriage license to get married in the Constitution State.

You don’t have to be a resident. But be aware that some states in the U.S. may not recognize your marriage if they prohibit first cousin unions.

If you’re not a resident, you must apply for the marriage license in the town in which you intend to get married. Residents can alternatively apply in the town in which they live.

You must fill out the application form in the presence of the town clerk. The clerk will ask you under oath if the information you provided is true.

As long as you have the appropriate ID and documents, the clerk issues the marriage license at the end of your appointment.

Be prepared for the possibility that the county clerk will ask you if you are related in any way. Don’t worry and just explain the relationship.

Does the Connecticut marriage form ask if you’re related?

Some states have a section in their forms where you must state a relationship e.g. first cousin.

You can see an example in our article on first cousin marriage in New Jersey.

We reviewed a Connecticut application form in 2022. It doesn’t ask for this information.

Who Can’t Get Married In Connecticut?

The Connecticut Family Code has quite a long list of relationships that are prohibited.

Here we go…

No man may marry his mother, grandmother, daughter, granddaughter, sister, aunt niece, stepmother, or stepdaughter…

nor a woman her father, grandfather son, grandson, brother, uncle, nephew, stepfather, or stepson.

Connecticut Family Code 46b-40, 60; 46b-21

Whew, that’s a bit of a mouthful.

The major point is that first cousins aren’t listed here, for either a man or a woman.

Connecticut laws don’t say explicitly that first cousins can marry. They simply don’t mention the relationship in their restrictions.

So, first cousins are good to go.

Do Cousins Travel To Connecticut To Get Married?

Connecticut is bordered by Massachusetts, New York, and Rhode Island. All three states allow first cousin marriage.

Other places share borders with states that prohibit such marriages. Occasionally, legislators or media express concern that hordes of out-of-state cousins are racing into the state to get legally married.

I don’t find any such concerns expressed in Connecticut. That’s probably because the surrounding states have similar laws.

Roman Catholic Marriages

If you want to celebrate your Connecticut wedding in a Roman Catholic church, you will face separate challenges.

Historically, the Catholic Church hasn’t been keen on first cousin marriages. However, the church laws have been relaxed somewhat in recent years.

There is a process you need to go through with the hierarchy in order to get permission to marry in a church ceremony. This is known as a dispensation.

We explain in detail in our general article on what first cousins are (scroll down to the end).

What about second cousins?

Second cousins (and further out) don’t need to get special permission for a Catholic Church marriage.

We suggest that you explain the second cousin relationship to your priest before the service. This means there will be no confusion for the celebrant if there is mention of “cousins” during casual conversation later.

If you’re not sure about whether you are first or second cousins, we have an article that explains how second cousins work. It has diagrams that make it clear.

Connecticut cousin gets backlash over a Catholic wedding

Back in 2012, a Connecticut Archbishop formally rebuked a local priest for participating in a marriage with his cousin.

But wait up. This isn’t quite what you think!

The unfortunate Connecticut priest had simply traveled to New York to attend the same-sex wedding of one of his cousins to another person.

The priest gave a reading at the non-Church ceremony. He was in plain clothes, apart from his collar.

The unfortunate padre was hauled over the coals by the hierarchy when he returned home. NBC reported that most of his parishioners thought this was unfair.

Yes, I know that this isn’t about first cousin marriages. But I just thought it was interesting!
