You don't want to do that. That's fraud. That will be found out. Not maybe. Will be. And then you will get charged with felony fraud. When dealing with an abusive ex, it's important that you keep your hands clean. Because of the doctrine of "clean hands," courts don't help people whose hands aren't clean. If you're committing fraud against Verizon and against him (because having him written off of an account by falsifying his death will appear on his credit report and make him dead to all his creditors and banks and cause all those accounts to be frozen and therefore is an act of fraud against him, too), then you don't have clean hands, and the court won't help you because the court will see that you are a party to the shenanigans, that you two are victimizing each other rather than he victimizing you. So if push ever comes to shove and you need the help of the courts to extricate him from your life, you will have screwed yourself by committing this fraud, because the court won't help you. The court will cite the doctrine of clean hands and say that you come to them in the matter without clean hands, and thus dismiss any claim or action you request against him.
