[Avodah] When Bittul Chometz precedes Mechiras Chometz

[Ben Waxman]

Last year I read the document that one signs with the Rabbinate about 
the mechira. It was quite clear - you sell everything.  Everything 
includes things that you may have forgotten about  and even things that 
you have no idea if you own, like stocks in some company that deals in 
chameitz (even if your ownership is via your pension fund). Everything  
means everything.

I asked around with several rabbanim and they told that "Truth of the 
matter is, once you sell your chameitz there is no real need to do a 
bedika. Anything in your house, whether you know about or not, is owned 
by the non-Jew."

The question that came up for me later was "OK, so we do a bedika anyway 
because that is the custom. But why say a bracha?".
