Son and his wife claiming right in property

I am senior citizen living in Uttar Pradesh. I purchased one property but due to loan obligation and under influence of emotions and buttery words of my son, I made him co-applicant in property so that he can take advantage of Income tax benefit. But after few months, My son's wife start torturing and threating me to put false allegation and case on me and my family and was not vacating my property after several requests. My Son was ready to vacate but due to his wife threats he was also not able to make her agree to vacate my property. I also gave a complaint in police that my son and daughter in law are torturing me to take my property but nothing happened. One day I asked my son to go on rent and take his wife along with him on rent or buy his own property and did not allowed them to enter in my property. Now my son's wife has filed a 498A and DV case and asking claim in that property as my son is co-allottee but I have made the payment only he gave loan emi. Can my son's wife claim rights in the property. My son is not living with me now as I don't believe him as these can be their tactics to take my property from me.
