Types of Divorce
Mutual Consent - Both the spouses are in agreement that divorce cannot be avoided and they both opt for a "no fault" divorce.
Contested Divorce - The spouse seeking divorce can file under the appropirate faith based law under which they got married or in case of civil marriage under the appropirate law under which they married or their marriage was registered.
Court Procedure

The spouse could contest or agree to the divorce. If he/she contests it then the length of the process would depend on the facts of the case.
