If your name is on the property, it is probably not necessary as selling it would require your signature. If your name is not on the property then you may have recorded at the time the matter stated a Lis Pendens indicating that you have a claimed property interest. You should probably consult with a divorce attorney in your area to review your paperwork and indicate what you can (or may need) to do.
