Q. Dear Rabbi, If someone was severely sick and a name was added, he got B”H well, When his children are called to the Torah, are they called with the new name that was added to the father? Thank you

A. Shulchan Aruch (E. H. 129: 18) rules that you have to write in a bill of divorce (Get) the new name that was added to an ailing individual, but only if the name change proved to be effective. Poiskim disagree if he did not survive for thirty days after the name addition, and he never actually used that name besides for the tefilos that were said on his behalf if that name stays and is included on the matzeivo and is also used by the sons when they are called to the Torah reading. Imrei Eliahu (E.H. 79) maintains that is the new name was publicized by the prayers said on his behalf, it should be maintained. Others opine that if the convalescent died from his sickness or if he never used the new name by being called himself to the Torah reading or signing etc., the added name should be omitted (Aleinu Leshabeach 1 p.610)

Horav Shlomo Miller’s Shlit”a opinion is that for the new name to be maintained, the ailing patient has to survive thirty days after a new name was added and it also has to be publicized by his own use of it.
