my spouse keeps on filing applications for seeking custody of my two daughters who had been deserted by their mother during 2008 and since then they have been reared up singly by me under love of grandparents and chahus (uncles). Since begining my daughters tie rakhis me, and both her chachus (my brothers). Now, since the mother is not having any love, affection to children despite she is meeting on her visitation days since 2008 every month. But now she wants to spoil all festivals, or such pleasant moments of my children which me and my family can enjoy with them.
Recently, she has filed application for custody of kids for observing rakhi with her brother's son.
Pls advise me how to argue to deny her application since it is purely an act of mischief on her and her parents's part. Advise urgently
