I ask a question on here about companies placing a equipment box on my property and was told that I could get rent for that box being there...

Usually utility boxes are placed on easements that have been granted previously by prior owners or  developers.  In that event no rent would be due as they have the right to use for their purposes.  If there is no easement, then you can demand that they remove the item.  If you want to negotiate for a payment or an easement, then an attorney would need to get involved to review and/or draft the appropriate documents.  You can contact the utility company to try to start the negotiations and and sometimes will draft the necessary documentation. However, I would suggest that an attorney review the documents to make sure that they are appropriate.  A local attorney could also determine an appropriate payment for the area. I cannot give you a referral since I don't know where you're located. This is specific to Florida law and does not constitute legal advice as the facts presented are anonymous and incomplete.
