Hi Chithra_Iyer,

The WCF FaultException (and FaultContract) data are all encapsulated via some certain fragment within the SOAP body (for SOAP XML format message). Therefore, it's not quite straightforward to add custom message headers for your SOAP Fault response. One method I can think is using custom message inspector. You can use message inspector to intercept the response message and check if it is a fault message. If it is a fault message, you can try adding some custom message headers into the outgoing response message. Here are some web reference about programmtically add message headers in WCF service (including using message inspector):
