From what I can see, you live in Bengaluru. While I don’t have any legal advice, knowing Indians, get ready for a lengthy process (if it comes down to it) because no sane person will give up on a property in such a city.
Also, there is a chance that there was a will written, however, it just took a lot of time to find the distant relative.
If the deceased left a will with a lawyer but didnโt tell anyone, and no one initiates probate or claims the estate, it might sit untouched indefinitely.
