Yaaleh Viyavo When Bentching

The following laws apply if you forgot to say Yaaleh Viyavo when bentching:

• If you remembered before saying Hashem’s name at the end of the berachah, go back and say Yaaleh Viyavo.
• If you remembered after saying Hashem’s name but before beginning the berachah of Hatov Vehameitiv, say the added paragraph for Yom Tov or Chol Hamoed (as appropriate) printed in the haggadah, siddur or bentcher.
• If you only remembered after beginning the berachah of Hatov Vehameitiv, the law will depend on when this took place: If it is on Yom Tov and during one of the first two meals, go back to the beginning of bentching (even if you merely said the word “Boruch”). However, if it is Chol Hamoed or during the third Yom Tov meal, do not go back.
