It sounds like she is cohabitating. If the contract states that alimony terminates based on cohabitation you can stop paying the alimony. However, she may sue you for breach of contract. If you end up in court the, court will make a determination and decide whether or not she is cohabitating. Before you take this step I would recomend that you meet with an attorney to review your Agreement, there may be specific language in your agreement that requires you to get permission before you stop paying. You may also have a problem because this issue existed before you executed the Agreement.
