I am not familiar with the evidentiary requirements under Georgian matrimonial law and whether grounds are necessary to receive a divorce in Georgia. In New York, grounds are required and the statute delineates six specific grounds for divorce. Adultery is one of the grounds.
Generally, the courts listen to the testimony of the opposing sides and determine the truthfulness of the testimony being given; they do not require eyewitness testimony in adultery cases.
