If it is a business transaction as codified in halacha, then let a contract, written or oral, be drawn up
Why do you say “if”?
And why does halacha suddenly stop when it comes to a contract? Halacha does not require it. It’s in the realm of eitzah tovah, and it’s not an eitzah tovah.
there you go again. stop whining. if you dont like what you do, stop doing it.
Is that what you want, fewer shadchanim? Who says he doesn’t like doing it? He doesn’t like being underappreciated. Nobody does.
