Affairs Don’t Matter in Divorce Proceedings in Most Cases
Your spouse is having an affair and now you are breaking up? You think that your spouse is having an affair and you want to catch them red handed with a private investigator? I am sorry to tell you that virtually no one will care about this in the legal system. It can certainly help you emotionally to know the truth but unless conditions are extreme it will not make any difference in New York, especially in Westchester County. In NY adultery is a low level crime so you must prove it at a criminal level, not the normal subjective bs of civil court. This means major expense and a whole new level of complication in your case that will not yield you much in the end except higher costs and maybe peace of mind.
So my advice is that even if you want to know about the affair for piece of mind don't tangle up your proceeding with the details. No one really cares about it and it is such an emotional issue that a predatory lawyer can easily exploit this to their benefit.
