How jurisdiction is decided in divorce cases?

I have filed a divorce petition on behalf of the husband on the ground of desertion. The parties were married at Place A. Thereafter, they resided at the husband’s original place of birth in City B for almost one year. Subsequently, they shifted to Place C due to the husband’s job. Within a few days of shifting to Place C, the wife left the matrimonial home and has not returned for cohabitation for the last 1.5 years. I filed the petition in City B. The wife did not appear, and the matter proceeded ex parte. However, at the stage of arguments, the Court has observed that the petition should have been filed at Place C or Place A and not at City B. I need to advance arguments on territorial jurisdiction.
