Claiming Property Taxes, but Not on Loan or Deed

[QuicksilverSoCal]

My question involves real estate located in the State of: California

My wife and I purchased property with 2 other people in 2003. We just found out that during refi at the end of 2004, my wife and I were not put on the loan or title. We continued to deposit or portion of the mortgage in a shared bank account for the 4 of us, used to pay house related bills and the mortgage. My wife and I were still claiming a pecentage of the property taxes in'05, '06, and '07, under the assumption we were still on Title. How should we handle this situation regarding claiming property taxes when we shouldn't have been? Thanks in advance for any advice.

A refinancing cannot take you off the title unless you signed a deed.
