Kaddish Titkabel for a Mourner during Shiva

Should a mourner say Kaddish Titkabel?

A mourner recites the order of Kaddish as usual.

In the responsa of Re'a Eya Tanina Kad, the custom is brought that Kaddish Titkabel is not recited in the house of a mourner. In Shu"t Maharam Shik Yoreh De'ah, Siman Sha, although it is written that this is not a proper custom, the custom is explained, as the Rema in Siman Shpd wrote that a mourner should not be a shaliach tzibur, and the reason is either because the attribute of judgment rests upon him or because of "karivahu na lephatecha." Today, this is not practiced, and it is explained that since the congregation prays silently the prayer that the shaliach tzibur repeats, it is not considered that he fulfills the congregation's obligation, and there is no problem. However, Titkabel, which the congregation does not say, and only the shaliach tzibur says, it is customary not to say in the house of a mourner. However, in practice today, it is customary that the mourner says Kaddish Titkabel.
