Is one required to both search for and nullify (bitul) chametz, or does one method suffice?
Synopsis
The Mishnah Berurah explains that min ha-Torah, either bitul (nullification) or bedikah (searching and destroying) alone would suffice. However, the Sages required both, because bitul depends on one's mental sincerity — a person with valuable chametz may not truly nullify it in his heart — and because people are accustomed to chametz year-round and may forget and eat it if it remains in the house.
