Getting ownership of long lived property

first of all check the old papers/documents pertaining to the said room & what is mentioned in that

it all depends on the content of the paper and check whether you are paying the house tax or your land owner is

paying the house tx from the tehsil i.e collector office.  and accordingly you can procede..

Thanks very much for your prompt reply.

The only paper we and he have is the bill which he issues on every payment. We or he dont have any other documents/'papers pertaining to this room.

We don't pay tax as he use to pay tax before on our behalf  but he stopped paying the property tax I guess though I am not sure. 

Thea bill is the only proof which he issues after every rent paid every month.

It has mention of 7 rules which has no law support.

1. The tenant is not authorised to rent out the property, if he does, both the tenant and the occupant has to vacate the room.

2. Rent should'nt kept due for more than one month which is the current month.

3. In case of any damaged to the said room, the tenant has to pay all the repair amount.

4. If a tenant want to vacate the room he/she has to give a prior notice to the land owner atleast one month in advance else the tenant has to pay the full month rent.

5. A tenant should always maintain the high level of decor in his behaviour.

6. Every month by 12 the tenant has to pay the rent in case of tenant vacating the said room he or she has to take a mention of this behind the reciept from owner.

7. The tenant shouldnt misue any property of the owner.

contact a local lawyer and proceed as per his advise, the house owner cannot evict you and his demands are high, so better remain stubborn, let him do whatever he wants, since this room is on the pagdi system, he may not be able to initiate any legal action except that he may try for demolition through municipality notice quoting the old age of the building.

Even if you stay for 100 years, a tenant will not become the owner.  The tenant cannot claim even adverse possession as he is in permissive possession (possession of tenant). As per the clause you cannot sublet (giving on rent to somebody).  If you sublet, the owner will get a ground to evict you from the premises. 

If you want to become owner you have to pay the cost of the property to the owner by executing a valid registered sale deed. Now start collecting the amount to purchase the property.
