Regard adding wife as co-applicant in bank account.

Dear Ajay sir, I would like to know about property buying when I am in break up of relationship. As I got married recently but unfortunately it was not fruitful as they have hided about her psychological disorders where I got cheated and due to this I informed their parents , initially they told about her mental illness and psychologic disorders but when it it came in to elders who set the marriage they have changed their tongue and now they were forcing and torturing me which I don't like to go further. Because of this i remain to be far from them. Waiting for time period of 12 mths. In the mean time I selected a property which i am willing to purchase on loan. Property will get registered on my name but when I approached banker for loan they said that I should attach co-applicant as my wife for legal heir. Which I don't like to. I want to add my father and mother name as co-applicant as it was their result of hardwork. And 50% property in that is my mother's share. So I would like to have some ways to purchase a property. What kind of risk I can face if I purchase and how to avoid risks. Required your suggestions
