Halocho #518 - If you forget to day Al Hanisim - עַל הַנִּסִּים on Purim

On Purim one adds עַל הַנִּסִּים to the Birkat Hamazon during the 2nd Bracha.

If you forgot to add עַל הַנִּסִּים and you've already said 'ברוך אתה ה then you don't have to make amends.

However, if possible you should say the following during the HaRachaman's after the 4th Bracha:

הָרַחֲמָן הוּא יַעֲשֶׂה לָנוּ נִסִּים וְנִפְלָאוֹת כְּמוֹ שֶׁעָשָׂה לַאֲבוֹתֵינוּ בַּיָּמִים הַהֵם בַּזְּמַן הַזֶּה בִּימֵי מרדכי

and then continue with the rest of the עַל הַנִּסִּים.

During every Amida of Purim one adds עַל הַנִּסִּים during Modim.

If you forgot to add עַל הַנִּסִּים and you've already said 'ברוך אתה ה then you don't have to make amends.
