Administrators are able to set default fee providers at the fee level within Fee Manager.
The below screenshot displays where a user can set default for Paid By/To to 'Borrower' with the Fee Manager.
The default fee will reflect within the Closing Cost Details page. Additionally, whenever someone is editing a fee they should always 'lock' it into the proper column weather it be borrower/seller/other paid. This can be done by clicking on the blue lock icon.
The user trying to make the change in Closing Cost Details must have the Privilege 'Closing Costs - Read Write' (this should be a default privilege for all LOs)
