You can file a request for dismissal which is a court form.  On the form, you can check the appropriate boxes; whether you want to dismiss the entire case or only specific causes of action (claims).  You will need to indicate whether the dismissal is with prejudice or without prejudice. If the dismissal is with prejudice, that means the case cannot be reintstated in the future.If the dismissal is without prejudice, that means the case can be reinstated in the future. Both you and your wife sign the request for dismissal and file it with the court.  Include an extra copy with a self addressed stamped envelope to receive a conformed copy (court stamped copy) for your records.
