Finding a Ketubah
There is a large variety of kitubot the market today. Some are made specifically for a couple by hand by a particular artist and thus will be quite expensive. Other beautiful decorative kitubot are created by artists through computer graphics; since they are not one-of-a-kind, they are less expensive. Of these kitubot some will be of a numbered limited series and others will not. These types of kitubot usually have the bride and groom's names and the place and date of the wedding set in seamlessly as part of the text so they do not look written in.
A couple who just wants the text of a ketubah or wants an inexpensive decorative ketubah can opt for a preprinted decorated ketubah. The rabbi will write in their names and the place and date of the wedding in Hebrew and English by hand. Couples who do not want a decorated ketubah at all and just require the text can copy one by machine that contains blanks for their names and the location and date of the wedding. The rabbi can fill it out for them to keep and treasure just for its meaning and the covenant between them that it represents.
Your ketubah supplier should provide you with a form to fill out the names of the bride and groom, their parents' names, and the date and place of the wedding. Be sure to run it by your rabbi to confirm the Hebrew spellings if required, as there can be more than one way to spell these in Hebrew.
If you are purchasing a ketubah that will be preprinted with your specific information or one that is being handwritten and decorated by a scribe or artist, you will need to give the artist, scribe, online purveyor, or Jewish bookstore through which you are buying the ketubah your information to put in the document. If your ketubah is to be in Hebrew and English you will need to supply your names, your parents' names, and the place and date of the wedding in both languages.
Different rabbis may want to use different kinds of information in the ketubah. Usually a ketubah contains the names of the bride and groom, their fathers' names, and often their mothers' names also. If your ketubah is only in English you may be able to supply all the information yourself, but if the ketubah is to be in Hebrew also you should check with your rabbi to be sure your wedding location, your names, and the date of the wedding are spelled correctly in Hebrew.
