The plaintiff in an Alienation of Affection case should establish ample evidence that the marriage was good before the defendant came into the picture and alienated the affections of the other spouse. This can include cards and gifts given to the plaintiff by their spouse during the marriage, romantic trips and vacations the spouses took together, wedding photographs depicting a happy family and other photographs of holidays and special events, etc.
The plaintiff will also need a clear timeline of when his or her spouse began to “lose interest” in the marriage as well as evidence to prove the relationship that existed with the defendant. Both can be shown through telephone records and credit card receipts among other things, as well as cards and gifts given by the defendant to the other spouse. The best evidence, however, is usually obtained through services of a private investigator.
