Money, materialism and greed is what drives and fuels the society today. Most people want the easy way to gain most money and suing to claim inheritence is an easy way indeed. We cannot judge as we do not know the full story of this, but a lack of understanding in what the father believes in, what the father wants to do and how high her father valued the Dharma would have also fuelled the daughter to take this course of action. She wants the money because she does not see why her father would donate the money to the temple, and she sees no use in it. Yes, indeed it is sad, and the girl might not realise the karmic implications of "taking" sangha money but I am not surprised that she has resorted to this. There are many worst things that society does today.
I guess it is good for her in a way that she lost the case. Maybe her karma was good so that she failed the case and didnt increase negative karma.
