A single judge of MP High Court at Indore bench held as follows,

From Para 13,

13. From the record, it is evident that learned JMFC has passed the order by dismissing the application under Section 125 of Cr.P.C. on the ground that
since the respondent did not get divorce from her earlier husband and without getting divorce she entered into second marriage. Hence, she cannot be
ascertained as a legally wedded wife of the petitioner and she is not entitled for the claim of maintenance.

From Paras 15-18,

15. It is unearthed from the aforesaid provision that an illegitimate child is entitled to get maintenance but an illegitimate wife is not entitled to get maintenance. The intention of legislature is obvious that maintenance can only be granted in favour of legally wedded wife. On this issue the law laid down by the full Bench in the case of Savitaben Somabhai Bhatia vs. State of Gujarat and Ors. reported as 2005 Lawsuit (SC) 466, is also poignant to be pointed out here:
“There may be substance in the plea of learned counsel for the appellant that law operates harshly against the woman who unwittingly gets into relationship with a married man and Section 125 of the Code does not give protection to such woman. This may be an inadequacy in law, which only the legislature can undo. But as the position in law stands presently there is no escape from the conclusion that the expression ‘wife’ as per Section 125 of the Code refers to only legally married wife.“
16. In view of aforesaid settled propositions and provisions of law, it is crystal clear that the wife should be a “legally wedded wife” for claiming maintenance from her husband. A woman, having solemnized second marriage to another person is only entitled to get maintenance from that person, when the first marriage has been declared either null and void or she has obtained a divorce decree from her first husband. The aforesaid view has recently been endorsed by this Court in the cases of Sangeeta Rathore W/o Naresh Rathore Vs. Naresh Rathore, 2023 LawSuit (MP) 470 and Kewal Singh Vs. Durgabai, 2024 LawSuit (MP) 179.
17. In conspectus of the aforesaid settled proposition, in this petition filed under Section 125 Cr.P.C., the term “wife” under Section 125 Cr.P.C. envisages a situation wherein she, having a living spouse, cannot seek maintenance from her second husband without getting divorce from her earlier husband. Nevertheless, this Court finds it unfortunate that many women, specially those belonging to the poorer strata of society, are routinely exploited in this manner, and that legal loopholes allow the offending parties to slip away unscathed and unquestioned. In spite of the social justice factor embedded in Section 125 Cr.P.C., the objective of the provision is frustrated as it fails to arrest the exploitation which it seeks to curb. In the instant case, while the Court sympathizes with the position of the Respondent, it is constrained to deny her maintenance as per the law of the land which stands as of today. However, the Respondent has the liberty to avail other remedies that may be better suited to the facts and circumstances of this case, such as seeking of compensation under Section 22 of the D.V. Act.
18. In the result thereof, the order of the learned Revisional Court awarding the maintenance to the respondent is found against the law and is also suffering from infirmity and illegality. Accordingly, the impugned order of the learned Revisional Court is set aside and the order of learned trial Court dated 06.09.2021 is hereby affirmed.
