YES, 50/50. But if you have been served it may be too late to sell. There are court orders within the paperwork that ORDER you not to sell property. Personal or Marital. Especially if you have been served an Order to Show Cause for Temporary Hearing. There the wording is clear and has been signed by a judge or commissioner.
Yes. Any asset sold or disposed of for one year prior to the divorce action can be "recaptured" in the divorce and included in the marital estate. You both must agree in order to sell any property. If you sell an asset, you will be charged with the value of that asset (regardless of what you sell if for) in the final property division in your divorce.
