Recommendations needed for Tax Lien at courthouse steps and Fieri Facias legal advice

[Russell R Massey]

ATLANTA GEORGIA
I need a recommendation for someone to give legal advice on a specialized topic - Do you recommend anyone? 

A property was vacant for 40+ years, tax lien sale on courthouse steps happened last december and someone won that. 
I have a few old Fieri Facias on the property and need to know my rights and options. 

I was also not notified of the tax lien sale.
