How to transfer property on my name

My Sister-in-law and I purchased a property in 2014. It is a one-story individual house. My family stays in the ground floor while my SIL's family stay in the 1st floor. I am self-employed and my SIL is salaried. Since I didn't have any income proof, we got a home loan in my SIL's name and the property was also registered in her name. The property value is 37 Lakhs. We paid a 14 Lakhs down payment and took a 23 Lakh home loan from DFHL. I have paid 7 lakhs out of the down payment and also transfer 50% of the EMI every month to my SIL's Account for the last 3 years. My name is not included in the property papers or in the home loan. My mother is a joint applicant in the loan but her name is not included in the property papers. I want my name to be included in the property papers to avoid any problems in future. I am willing to take a loan for my share of the remaining loan amount (about 10 Lakhs). My SIL is willing to sign to setle this issue amicably.How do I go about this?
