Dissolution of marriage is filed when two people who have been legally married, and one or both of them goes through the court process to have the marriage ended.Dissolution is the formal, legal ending of a marriage by a court, commonly called a divorce. A dissolution of marriage completely ends your legal relationship as spouses and ends your marriage. Unlike an annulment, a dissolution does not “undo" the marriage as if it never existed.A Petition for Dissolution of Marriage is a type of court document that is used for initiating a divorce proceeding.  The petition lets one spouse inform the other that they seek a divorce or dissolution of the marriage. It also informs the courts of potential issues that might be a factor in the divorce proceedings, such as spousal support, child custody, and other factors. 

The process of dissolution is started by filling a petition for divorce by mutual consent.For claiming dissolution of marriage the parties to the marriage have to agree on various issues such as custody of child, alimony to wife, property issues etc. whereas in case of divorce such issues are settled by the court itself.If the parties can negotiate and come to an agreement on all terms of their separation agreement, then the parties can petition for a dissolution. A dissolution of marriage can alleviate a lot of the divorce process and expense by eliminating the need for court involvement during negotiations. In a dissolution, once the parties reach agreement as to the details to their separation agreement, the agreement can be filed with the court and a final merits hearing can be scheduled. Dissolution can be more streamlined than a divorce.
