Divorce property

In love, got married in 2003, after 2yrs in-laws wanted us to buy house, so transfered INR 1o Lacs into my a/c, out of which bought a 1RK for 7.5 Lacs in both our names i being the primary, paid 1Lacs personal loan, rest spent on us. Now afted 3yrs of staying apart without any contact planning for divorce, as she dont want to stay with my dady who is 75yrs of age and alone. Will I be entitled to pay 50% back or less or more. We have a boy child 5yrs of age in her custody. havent paid expenses since we are not together
