Hello 

I have the advice but it might be right to discuss it here at open platform. 

Let me know where to suggest you.

First issue legal notice to him to evict within prescribed period if he Denys file suit for eviction.

Process of evicting a tenant in India

1. Step 1 – Send a notice to the tenant to vacate. ...
2. Step 2 – File a suit for eviction. ...
3. Step 3 – Final notice for eviction.

Hello!

An eviction notice must be filed in a court of competent jurisdiction, stating the basis for eviction as well as the time and date by which the occupier must leave the property, and it must then be issued to the concerned person. A reasonable time limit must be given to vacate the property. 

The court hears both parties and, relying on the arguments and facts presented, issues a final legal notice of eviction for the tenant. Once the court issues the final eviction order, the tenant must leave the rental property as they cannot overlook this notice. 

What is the easiet and quick way to kick him out of that house, any legal / court proceedings would it drag the matter for years?

Yes court proceedings will take years. 

Is/was your brother-in-law paying rent? Are there any common services to the whole building for which the tenants contribute other than the rent they pay?  What are the other services? Have you given written notice to your brother-in-law?  Has he given written reply?  What is his reply?

How old is your brother-in-law?  Has he got a family?  How many members are there in his family, adults, children?  Where are your parents-in-law? Has your husband got other brothers and sisters? Where are they?   If you have not yet gone to court, please wait.
