my father's older brother does not want to take care of their mother as she is old and needs attention. They both have lived separately and my mother also passed away last year. My uncle takes full advantage of this situation and doesnt want to take care or share responsibilities of his mother with his brother. My father takes care of his mother and mother in law both, despite losing his wife, for a very long time. He also took care of his father till he passed away. My uncel has never taken any are of his parents saying his wife is overpowering and does not allow him to take care of them. Now since my father is also working he requests his brother to share and take care of their ailing mother, which he denies or takes her with him and brings her back in 3-4 days saying she is old and I am not able to take care. Now the entire responsibility and burden of her has to be done by my other grandmother who is also old by relatively healthy. All we ask him is to take atleast share some responsibilities when my father has to attend some function or travel as she cannot be accompanied everywhere.
Mu uncle also took share of the ancestral property which was sold a few years back, but when it comes to share responcibilities he shies away.
Is there anything we can do or any provision in law which can sort this situation??
