How can I claim share in property received by husband in partition

I am a working woman, who looked after her dau and her hub since marriage. my hubby was non working, alchoholic, cheated me many times financially. he had a brain stroke 3 years back, where in i spent 3 lakhs for his hospitalization by taking loan from friends and my company.still i pay the loan for the same.His mother sold their native property and gave shares to her 3 sons (my hubb is a middle son).But out of that too he didnt gave me a penny nor he saved the same for his dau.After my mother-inlaws death,they sold her flat.The eldest son died before the deal went off. he didnt gv to us.
