Whether your husband had the right to sell his interest at all might be an interesting question, and I'm not a New York lawyer;  this is a point on which some states might differ, although usually a person can do this.However, once he did it, if it's valid, he destroyed the tenancy by entireties, and you are now a tenant in common with whoever, or whatever business entity, bought your husband's half.  This difference is important, because now, entirely apart from a divorce, you can file a lawsuit for what is called, in most states, partition, which will force a sale of the property.I'd strongy urge you to have a New York attorney consider all the facts of your case;  if possible, you should do this in a way that avoids letting your husband get half of what you get for your half of that house, in a divorce.  One place to find a qualified lawyer is our website, http://attorneypages.com
