The correct term is actually "head of family." Head of household is the IRS term.
Here is the statutory definition, it answers your question:
(c) “Head of family” includes any natural person who is providing more than one-half of the support for a child or other dependent.
FL Statute 222.11(1)(c).
Attorney Berkus is correct. Without a minor child you will not qualify for the head of household exemption.
If you cannot afford to pay the judgment you may want to consider a bankruptcy case. Filing a bankruptcy would immediately stop the garnishment process and would discharge the debt. You should consult with a bankruptcy attorney to see if you qualify for a Chapter 7 case and if it is a good option for you.
A child or other dependant would include a spouse.
