Georgia Code Title 51. Torts § 51-11-10

(1) A land surveyor possessing a certificate of registration issued by the State Board of Registration for Professional Engineers and Land Surveyors has surveyed the property from which the timber is to be harvested and plainly established and clearly marked the metes and bounds of the property such that a reasonable person would know or should have known of the existence of such markings when harvesting the timber and has provided a copy of that survey to the third-party timber harvester;

(2) The boundaries of the property from which timber is sold have been completely and accurately indicated using physical markers that are clearly visible such that a reasonable person would know or should have known of the existence of such physical markers; or

(3) The property owner has obtained a document indicating where the boundaries are and signed by adjoining landowners indicating that they agree on the location of such boundaries and has provided a copy of such document to the third-party timber harvester; provided, however, that such document shall only create a presumption in favor of the property owner with regard to those landowners who have signed such document.
