A father who spends the Seder with his son and grandchildren, who should recite the Hagada the grandfather or the son who is after all the ‘Baal Habait’ (house owner) and the father of the children?

On a similar question (3632) we wrote: “The mitzva of Sipur Yetzias Mitzraim or telling the Haggadah story applies to a grandfather also. (See Talmud Kiddushin 31a in regard to the mitzva of learning Torah that it applies to grandchildren also). Teshuvos Vehanhogos (2: 236) maintains that it is even a greater mitzva for the grandfather to tell the Haggadah to the children. Chassam Soffer’s opinion is that the grandfather should tell his son, and the son then should tell his children It would seem that the best way is to divide time. The father should explain shortly to his children the answer to their four questions. The rest of the Haggadah that as is is hard for them to understand and keep attention to, should be recited by the grandfather that as is (if it is his home) is leading the Seder. A father complies with this mitzva even if his children area grownup and also already Talimidei Hachamim. (Rambam H. Chometz Umatza 7:: 2-3).
