Judy, as Deb Madey stated, in some parts (as is generally the case where I am in Ocean County) the Realtors are very involved and often like to see a copy of the commitment.
So that I cover myself, I always send an email to the borrower confirming that they don't mind because the conditions can contain some sensitive information at times. Though I don't recall any specific law regarding the commitment, common sense tell me that it falls under your general privacy rights-as Robin has stated.
Fortunately for me, I never had a client who refused to allow me to forward the commitment. Is there a specific reason that you don't want your Realtor to see the commitment?
