We are a hindu family and my father is an adopted son of my grand parents. Grandfather left a property to my father in his will. What are the rights of my mother towards that property.
Your mother as a legal heir to your father can claim a share in his intestate property after his demise if he had not bequeathed he property through a Will.
There are maritial disputes between father and mother and he is threatening to give the property to his relatives and not to his family (mother and children). Can my father legally do that?
Your father is the absolute owner of his property, he has rights to dispose the property in any manner he may desire to do so. Your mother nor you can restrict him legally from proceeding that way.
The property is used for both residential and commercial purposes. A school is run on the property for past 25 years jointly by father and mother.
If your mother is a partner in the school business, she can claim her due shares in the income so generated through the said business, she can even drag him to court seeking her share of income form the business.
