Except as provided in (g) and the IOLTA Rules below, funds shall be kept in one or more separate interest-bearing client trust accounts maintained in a bank, credit union or savings association:
A lawyer who either remits funds in error or later ascertains the ownership of remitted funds, or the owner thereof, may make a claim to the Louisiana Bar Foundation, which after verification of the claim will return the funds to the lawyer or owner, as appropriate.
