how to get payoff info from a subject to loan?

[Rachel Zhang]

We bought a property in CA at a trustee sale with an existing senior lien under the previous owner's name. Now my title company and I are having difficulty in obtaining payoff amount. By standard, the serve company requires the lien holder's SS /loan # or authorization to release payoff.  Even through I faxed over the trustee's deed upon sale, the reps won't understand or do not care, always give me the standard response. Shall I try different title company? By law, the trustee's deed upon sale should serve as an authorization to release information. Right? Are there any specific language in the mortgage or the law to indicate such? This loan is delinquent, and I am offering to pay it off. where wont' they give to me?  Thanks for your response. Rachel
