Transfer of property void when tax due to protect revenue, unless adequate consideration, no notice, or officer permission. Transfers or acts by a taxable person executed after a tax becomes due that create a charge on his property by sale, mortgage, exchange or any other mode of transfer are void to the extent they defeat recovery. Exceptions: transfers made for adequate consideration without notice of pendency or without notice of the tax or other sum payable, or made with the previous permission of the proper officer.
