When to tear kriah

Hi,

One who hears of a close relative's death recites a blessing, 'Blessed are you Gd, King of the universe, who is the judge of truth,' in an initial attempt to religiously handle his grief. It is at this point that the mourner tears his clothing.

This generally occurs before burial, although one who hears of a death after burial should still recite the blessing and tear his clothing.

(Code of Jewish Law Yoreh Deah 339:3, 340:1; Shach Yoreh Deah 340:3)

Have a good day,
Mordechai
