4. Cases of exception in which the Shiva begins before, or sometime after, the burial:

In certain situations, the Shiva begins before or sometime after the burial. A competent Rav is to be contacted in all of these cases. The following is a list of these situations:

1. One is planning to rebury the body elsewhere. [See Halacha 5]
2. The body cannot be found or buried. [See Halacha 6]
3. One will not be attending the funeral/burial. [See Halacha 7]
4. One discovered the death only after the burial. [See Halacha 8]
5. One who transgressed and did not keep Aveilus. [See Halacha 9]
6. A Chasan and Kallah [See Halacha 10]
7. A Yom Tov has arrived [See Halacha 11]

*Important note regarding Aninus:

The laws of Aninus and the mourner’s status of an Onen, always ends before one begins Shiva. Thus, in all cases brought below in which we rule that Shiva begins prior to the burial, the state of Aninus also ends at that time. Furthermore, as evident from the Poskim[1], it is possible to have a limbo period where Aninus has ended, but Shiva has not yet begun. See Chapter 3 Halacha 2 for the full details relating to the end of Aninus, and those cases where it ends even prior to the burial.
