The procedure for filing divorce and legal separation is almost the same. There's not that much difference between them. The only difference between them is that divorce is the complete end of marriage whether legal separation is only physical separation. A legal separation process is less costly and not that time taking than a divorce.
Divorce proceedings are comprehensive and begin with the filing of a Petition for Dissolution of Marriage. A case file is opened and a judge is assigned to the case when the Petition is filed.
