1. The property waws owned by your grandfather and after his demise, all his 4 children have equal mshare on it,
2. The fact that your father's family is enjoying the said property alone since last 30 years does not entitle you the entire property,
3. Your father is entitle to only 1/4th share of the property,
4. If your two buajis relinquishes their shares to your fahther then he will be entitle to 3/4th share of the entire property,
5. If they relinquish their share equally in favour of their two brothers then your father will be entitled to 1/2 share of the said property,
6. Your Tauzi can file partition suit which will take years to be disposed of,
7. He can not demolish the property,
8. So relax and wait till he files the partition suit which your father can contest to drag it for years,
9. Your weakness is that you do not have money to contest the case and the problem your Tauzi has is that he stays at Dubai and can not visit India regularly to oversee the case filed by him.
