This should be a one-time process that is needed because of the transition from Families to Households. If this is not done, it can cause many strange issues with Households and Guardians, including DELETING parent addresses if parents do not live together.
Navigate to the Households split application in the Households menu
Select a Household from the list on the left.
If the addresses are Different (the two parents/guardians live at separate addresses as in the first screen shot), click Split. This automagically creates separate Households for separate guardians.
If the addresses are The Same (the two parents/guardians live together as in the second screen shot), click Merge. This tells WVEIS that the addresses are the same and cleans up the record.
If it's Complicated and neither Split nor Merge are a good fit, click Ignore. This tells WVEIS you'll take care of it yourself. Give us a call if you want help!
