1,291. Moving the Body
199:11 We don't move the deceased from a city that has graves available to another city as it is considered disrespectful to move the deceased from place to place except to move him to Israel from outside Israel, or to move him to a place where his ancestors are buried. Similarly, if the deceased left instructions to move him from one place to another, then it is permitted.
199:12 We are not permitted to open a grave after the lid of the casket has been covered with dirt. So long as the casket has not been covered with dirt, it is permitted to open it if circumstances so require. If there is a need to exhume the deceased from his grave, a Torah authority must be consulted.
