Non-Jews using a Jewish Wedding Contract

In the wedding industry it's becoming trendy to sign a Jewish ketubah, (the traditional Jewish marriage contract) even for those who are not Jewish or Christian.. or religious at all. Many are even adapting to other customs: "More non-Jewish couples have embraced Jewish marriage rituals over the last decade. Some stomp a glass – or a lightbulb [sic] as a popular substitute. Others recite vows under a canopy, called a chuppah."
There is an increase demand for non-Jewish ketubahs because "a ketubah is more than just fancy calligraphy. It's often poster-size and ornate, suitable for framing later with artwork either as backdrop or accompaniment." People seem to like it mostly for aesthetic and sentimental reasons.

One Ketubah creator says, "I always felt it was something that everybody could have . . . I didn't see why it should just be for Jews. It can be the thing that reflects the spirit of the day, more than those 50,000 photographs you took at your wedding. It's just a nice energy."
The article concludes that many Jewish traditions are becoming mainstream without their religious associations, and this is one example proving the claim.
