On an option, you would typically record a Memorandum of Option instead of the whole option with all the details for the world to see. This is sufficient to cloud the title and let the world know that you have an interest in this property so that the seller can’t just turn around, disregard your option and sell to some else IF the seller isn’t allowed that per the option.
Usually on an assignment you are getting your money right then and there or pretty close to it and normally isn’t necessary. But whatever is notarized should be able to be recorded against the property.
