Translation:Shulchan Aruch/Orach Chaim/435

1. '''The law regarding one who did not check on the night of the 14th. And within it, one clause:'''

If one did not check on the night of the 14th, they should check on the 14th day at whatever time they remember. If they did not check the entire 14th day, they should check during Passover. If they did not check during Passover, they should check after Passover so as not to fail regarding leavened bread that passed over it during Passover, which is forbidden for benefit. And concerning the checking after Passover, one should not recite a blessing.
