The petition filed by or mother udner section 125 (3) is for collection of arrears.
There is no legal infirmity in filing this case especially when there is no order restricting the trial court to stall the proceedings.
You should have filed a petitoon seeking to stay all the proceedings in the trial court pending disposal of the revision/appeal before the district court.
You say that you filed the appeal in the year 2021 but she filed the collection petiton in the year 2024 only.
Then who is to be blamed for not filing an applicaiton for stay of all the prioceedings in the trial court.
Why did this thought did not come to your mind when you filed the appeal before the district court in the year 2021?
You keep saying that your mopther is occupying your father's property despite the fact she is a divorceen and her marriage with your fatgher was dissolved by a decree of divorce.
In fact she has no rights in that property because she is no more a legal heir to your deceased father after divorce.
You as one of the legal heirs of your father has a right to inherrit a share in the property left behind by him, hence you file a suit for partition and seek to eject her from the property.
Even now you can inform the trial court that there is an appeal pending before the district court hence to stall the proceedings in the new case till the disposal of the appeal.
In the name of changing the lawyer you have jumped into the fire from the owen.
Now it depends on your own intelligence to handle this matter more properly on the basis of the bitter experiences you had gained so far
