I'm not sure there is anything you can do legally. You could show up at the service and tell the officiant you are still married. If he is able to marry her before getting divorced you can notify the police.
I am a former federal and State prosecutor and have been doing criminal defense work for over 16 years. I was named to the Super Lawyers list as one of the top attorneys in New York for 2012 and 2013. No more than 5 percent of the lawyers in the state are selected by Super Lawyers. Martindale-Hubbell has given me its highest rating - AV Preeminent - in the areas of Criminal Law, Personal Injury, and Litigation. According to Martindale-Hubbell”AV Preeminent is a significant rating accomplishment - a testament to the fact that a lawyer's peers rank him or her at the highest level of professional excellence." Fewer than 8% of attorneys achieve an AV Preeminent rating. I also have the highest ranking – “superb” – on Avvo. The above answer, and any follow up comments or emails is for informational purposes only and not meant as legal advice.
I agree with Mr. Rothstein in that there is no way to prevent the parties from going through with the event. With that said, if you are still married to him then he cannot marry anyone else. Any subsequent "marriage" will be void until the two of you divorce.
