Property Vacation

I am 70 years old NRI from the UK. In 2008 my mother left her house (in Chandigarh) on my name in her will and that house got transferred on my name. 10 years ago, I helped my family friend's family to stay at that house in Chandigarh as they were in financial difficulties. I never took single rupee from them and there in no rental or any other oral or written contract between us. Since two years I am asking that family to vacate my property. In the beginning they said that they are looking for rental place as soon as they will find suitable place accordingly they will move out. Then in the Covid period I didn't ask them to move out. Since January 2021, I am again asking them to vacate my property. Now they told me they don't have money to move out, they will move out when they will be able to buy their own place. They are staying at ground floor, no one is staying at first and second floor. I got access to the whole property. Kindly advice me how to vacate my property and how long it can take. I don't have children, if I leave that house to someone in my will, would that person be able to get that house.
