Sec 6(f) of tpa

Grant of interim maintenance/maintenance passed by principal judge of family court can be challenged in High court. ... You may challenge the order in High Court withing 30 days of the orders and it is possible that the High Court will pass suitable orders. The case must be filed before due period. 

Thank you, sir, but my main contention behind the question was, whether the salary of a government official is attached to the decree of maintainence. If you could please clear my doubt, I would be obliged

 

As the question concerning you, let me inform you that the exemption of first Rs. 1000/- of the salary also does not apply for a maintenance decree.
Thus, it means that un maintenance decree 2/3rd of the salary can be attached without deducting anything else as UN-ATTACHABLE PORTION.
