Example of Florida Homestead Law
George and Martha live on a one-acre lot in Tampa, Florida. The property is worth approximately $500,000.
The Constitution affords protection only to one-half acre lots in a city. The homestead protection would apply to 50% of the $500,000 value, or $250,000.
George and Martha may not survey the lot, allocate the protected portion to the physical dwelling, and then allocate the unprotected portion to the less valuable backyard. A creditor can record a judgment against the property and force its sale. The creditor would get $250,000 of the sale proceeds applied to its judgment.
