What Do The Delaware Marriage Laws Say About First Cousins?

A marriage is prohibited and void between a person and his or her ancestor, descendant, brother, sister, half-brother, half-sister, uncle, aunt, niece, nephew or first cousin.

As you can see, first cousins are explicitly named at the end of the list.

Blanket ban

Some other states generally don’t allow first cousin marriage but have some allowances based on age or other criteria.

In contrast, Delaware has a blanket ban within the state. There are no special exceptions.

How first cousins are legal in other states

Many other states have similar long lists of prohibited relationships in their marriage laws. But they stop short of mentioning first cousins.

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

That’s why these marriages are legal in these other states.

Well, there are other sections of Delaware family law that get specific about these relationships.

For example, there is a section in the Delaware Code that defines who can be relational caregivers of minors. This section lists persons who are “first cousin or first cousin once removed”.

I mention this just to note that the legislators of marriage law didn’t just forget about this relationship.

What Would Happen If First Cousins Marry In Delaware?

Under the marriage laws at the time of writing, both spouses are guilty of a misdemeanor.

The officials who solemnize the marriage are also guilty if they knew about the relationship.

What if the couple didn’t know at the time?

An invalid marriage should be grounds for an annulment.

There have been cases in other jurisdictions where marriages were successfully annulled when the couple told the courts they hadn’t known they were close cousins.

If you find yourself in this position, you should consult a lawyer as quickly as possible.

What are the penalties?

A conviction could bring a fine. If the fine isn’t paid, then imprisonment is a possibility.

We haven’t found any examples of convictions in recent years.

Does The Delaware Marriage Application Form Ask If You’re Related?

Some U.S. states have a section in their marriage application forms where the couple must state whether they have a blood relationship.

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

We reviewed the Delaware form in 2022. There is no such question present.

Does Delaware Recognize First Cousin Marriages From Other States?

At the time of writing, Delaware does not recognize first cousin marriages conducted in other states.

This is the relevant section in the state laws:

A marriage obtained or recognized outside the State between persons prohibited by subsection (a) of this section shall not constitute a legal or valid marriage within the State.

Roman Catholic Marriages

Even if close cousins move to another state that allows their civil marriage, they will face separate hurdles if they want a wedding in a Roman Catholic church.

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

There is a process that first cousins 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 first cousins (scroll down to the bottom).

What about second cousins?

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