Asking Halachic Questions


Sometimes, a bedikah cloth or a stained garment must be brought to a halachic authority to determine whether it is problematic. (Brown, black, pink, or orange stains generally require a question.) It is to a woman’s benefit to ask a question rather than just “wait another day or two”.This is particularly true in cases where one is trying to conceive.

The cloth or garment with the stain should first be left to dry undisturbed in a clean place and then placed into a clean plastic bag or envelope.

In some communities, yoatzot halacha are available to evaluate cloths and stains. Click here for a directory of yoatzot in North America and England. To find a yoetzet in Israel, please write to us or call our hotline.

Some women feel comfortable bringing a cloth or undergarment directly to a yoetzet or rabbi. Other women prefer to ask their husband, or the rabbi’s wife, to serve as an intermediary when consulting a rabbi. A yoetzet or rabbi may have a mailbox or other location where you can leave a cloth in an envelope with a covering note; you should first make certain they are in town and will receive it promptly.

In order to give an accurate ruling, the halachic authority should have the following information (if you are not asking the question in person, include a note):

1) Your name (optional) and phone number, email, or other way to contact you (mandatory). The process can be done anonymously without giving your name. (You can even leave an assumed name with your phone number.)

2) For a bedikah cloth – on what occasion was the bedikah performed (e.g.,hefsek taharahmoch dachuk, on which of the seven blood-free days, on which day of anticipated menses)?

3) For a stain – at what point in your cycle did it occur (before or after mikveh immersion, during the seven blood-free days, on a day of anticipated menses)? Did you feel a hargashah before discovering the stain? Do you know of any plausible alternative source for the stain?

4) Any relevant medical information (e.g., recent medical testspregnancy, childbirth, or miscarriagemidcycle stainingIUD or contraceptive pills).

5) Any extenuating circumstances (e.g., difficulty conceiving, difficulty in getting to the mikveh within a reasonable time, your wedding is imminent).

6) Any other information you think might be relevant.

Whenever possible, the actual stain or bedikah cloth should be brought to the halachic authority for evaluation. When a woman does not have access to a halachic authority, we recommend Tahor App, which uses sophisiticated color calibration technology to allow women to send accurate photographs for rabbinic evaluation. Tahor is currently available for iPhones and for some models of Android phones. If necessary, it is also possible to send cloths by overnight mail or delivery services.

This page deals primarily with questions of stains and bedikot that need to be evaluated visually by a halachic authority. Other niddah questions – like halachic questions about Shabbat, kashrut, and so on – can be asked in person, over the phone, by email, Whatsapp or Messenger, and so on. Yoatzot halacha answer questions in the community, through this website and over a telephone hotline.
