Read for yourself. This is the judgment of Hon’ble Apex Court which held that interim maintenance can be given in a Sec 125 CrPC case.

From Para 6,

6. In view of the foregoing it is the duty of the court to interpret the provisions in Chapter IX of the Code in such a way that the construction placed on them would not defeat the very object of the legislation. In the absence of any express prohibition, it is appropriate to construe the provisions in Chapter IX as conferring an implied power on the Magistrate to direct the person against whom an application is made under section 125 of the code to pay some reasonable sum by way of maintenance to the applicant pending final disposal of the application. It is quite common that applications made under section 125 of the code also take several months for being disposed of finally. In order to enjoy the fruits of the proceedings under Section 125, the applicant should be alive till the date of the final order and that the applicant can do in a large number of cases only if an order for payment of interim maintenance is passed by the court. Every court must be deemed to possess by necessary intendment all such powers as are necessary to make its orders effective. This principle is embodied in the maxim “ubi aliquid conceditur, conceditur et id sine quo res ipsa esse non potest” (Where anything is conceded, there is conceded also anything without which the thing itself cannot exist). [Vide Earl Jowitt’s Dictionary of English Law, 1959 Edn., p. 1797.] Whenever anything is required to be done by law and it is found impossible to do that thing unless something not authorised in express terms be also done then that something else will be supplied by necessary intendment. Such a construction though it may not always be admissible in the present case however would advance the object of the legislation under consideration. A contrary view is likely to result in grave hardship to the applicant, who may have no means to subsist until the final order is passed. There is no room for the apprehension that the recognition of such implied power would lead to the passing of interim orders in a large number of cases where the liability to pay maintenance may not exist. It is quite possible that such contingency may arise in a few cases but the prejudice caused thereby to the person against whom it is made is minimal as it can be set right quickly after hearing both the parties. The Magistrate may, however, insist upon an affidavit being filed by or on behalf of the applicant concerned stating the grounds in support of the claim for interim maintenance to satisfy himself that there is a prima facie case for making such an order. Such an order may also be made in an appropriate case ex parte pending service of notice of the application subject to any modification or even an order of cancellation that may be passed after the respondent is heard. If a civil court can pass such interim orders on affidavits, there is no reason why a Magistrate should not rely on them for the purpose of issuing directions regarding payment of interim maintenance. The affidavit may be treated as supplying prima facie proof of the case of the applicant. If the allegations in the application or the affidavit are not true, it is always open to the person against whom such an order is made to show that the order is unsustainable. Having regard to the nature of the jurisdiction exercised by a Magistrate under section 125 of the code, we feel that the said provision should be interpreted as conferring power by necessary implication on the Magistrate to pass an order directing a person against whom an application is made under it to pay a reasonable sum by way of interim maintenance subject to the other conditions referred to therein pending final disposal of the application. In taking this view we have also taken note of the provisions of Section 7(2)(a) of the Family Courts Act, 1984 (Act 66 of 1984) passed recently by Parliament proposing to transfer the jurisdiction exercisable by Magistrates under section 125 of the code to the Family Courts constituted under the said Act.

Note: By way on an amendment to Cr.P.C. 1973 in 2001, the Parliament brought the following two Provisos.

Provided further that the Magistrate may, during the pendency of the proceeding regarding monthly allowance for the maintenance under this sub-section, order such person to make a monthly allowance for the interim maintenance of his wife or such child, father or mother, and the expenses of such proceeding which the Magistrate considers reasonable, and to pay the same to such person as the Magistrate may from time to time direct:
Provided also that an application for the monthly allowance for the interim maintenance and expenses of proceeding under the second proviso shall, as far as possible, be disposed of within sixty days from the date of the service of notice of the application to such person.
