One of Judaism's most sacred and ancient traditions, is the Kaddish prayer. Traditionally, the Kaddish prayer is recited in the merit and memory of a loved one who has passed on from physical life.
The Kaddish prayer is a great merit and source of elevation for the soul of the loved one.
Kaddish is recited for a period of 11 months starting after the time of passing. It is also recited once a year on the Yahrtzeit (anniversary of the passing.)
Ideally the children of the deceased recite the Kaddish three times a day for the first 11 months after the passing.
In the event that children cannot recite the Kaddish, one can donate money to a charity that helps the poor and needy in the Holy land, in return a Torah scholar will be appointed to recite the Kaddish in the merit of the deceased.
