Click on Official Records Listing on the left side. If the HOA has placed a lien on the property, it will show up there. Keep in mind that the dollar amount listed on the lien will not include any interest that may have accrued.
If you do not know the owner's name, you can find it on the Property Appraiser's website - you can do a look up with the property address. http://www.co.palm-beach.fl.us/papa/index.htm
