No adverse possesion. And you should have taken objection when neighbour not left the space as per rules.

Since he is digging in your area, it is illegal, complain to police. 

He cannot claim adverse possession by merely laying pipes on gap between 2 houses 

file suit seek orders to direct neighbour to remove gate installed in gap 

- Since, there is no written agreement between you and the said neighbour , for leaving any space .

- Further, with the left space by you , now it become common gap for you both . wherein he already put a small gate for the purpose of using the said gap . 

- Presently due to good relation with him , you dont want to raise any issue over the same, but in future that neighbour may claim the said full space as his personal property on the ground of using the same ie. adverse possession. 

- Hence, you can enter into a soft agreement with him , that out of the gap , 1.5 ft ft space is under your ownership , and he will not claim over the same in future. 

- If, not agree , then you can file a suit for getting order from the court . 

- However , try to settle the matter amicably , as i mentioned above. 

The set back area left by you belongs to you exclusively in which your neighbor has no right title to raise any construction. 

So the digging of pope in your area amounts to encroachment of your land for which you can lodge complaint with local police station. If this doesn't put an end to this illegal act your option is to file a suit for declaration and injunction. 

1. Obtain Injunction Order from the competent court to stop illegal digging by your neighbour.

2. Anyway Police can't be summoned to stop this illegal act of your neighbour as it's a civil matter. 

3.  Complain to the jurisdictional BBMP office regarding this matter and request for BBMP's intervention.

4.  He can't claim adverse possession as 12 years has not elapsed since as per your narration the gate was installed in 2011.

5.  Send a legal notice to your neighbour claiming right over the land where your neighbour has trespassed and illegally digging the land.

Send him a legal notice and ask him to stop doing this

If he still doesn't take any action than file a specific performance suit against him 

Dear Sir,

You are suggested to stop the digging work done by the neighbour in your land and ask him to do in his own land. Also complaint against him to concerned authorities as required, He can't claim adverse possession on the said land. You may also file an injunction suit against him restraining him to use of the said property.  

Hi

Though technically you have left 1.5 feet in accordance to building construction rules, the land still belongs to you and it is a plain infringement of your ownership rights. 

Also open spaces are called set backs in building parlance and no construction (either above the ground or below the ground) can be undertaken.

Please issue notices to Municipality and also the neighbour restraining from undertaking any activity and if that fails, you can obtain injunction orders against the neighbour under Order 39 of CPC 

Your neighbour cannot claim adverse possession.

Hope this information is useful. 

No, it does not favor him Adverse Possession.

You issue legal notice to him to remove the pipe line and gate.

If he does not respond / refuse to remove the same, you can file suit against him and pray the court to direct him to remove the Gate installed in 1.5 ft space.

You can also lodge police complaint for trespassing into your property by him (optional) if he still continues with his activities.

This is a setback you have left as per law and rules. 

He cannot claim title on this passage by adverse possession. 

You can issue a legal notice to him to stop him from proceeding with his proposed laying of pipes in this passage, if he is not listening to your verbal requests. 

After that you can file an injunction suit seeking to restrain him from proceeding with his proposed construction. 

You need to file a suit for injunction and take immediate measures to stop the work under interim relief

You can seek injunction against the neighbor from a civil and can restrict to digging or construct any thing which infringe you rights. It is highly advised to take early step as if once construction is started you shall be running against time. IN courts an early bird is always in better position.. 

1. Adverse Possession comes into play only if the possession of trespasser is hostile to the possession of true owner.

2. Who is the owner of the land where the neighbour is digging?

3. You can file a complaint against your neighbour to the civic authority in your city which has jurisdiction over the area.

You can seek stay against him and also file a complaint to the authority concerned.No adverse possession can be claimed by him, as for the same, he has to prove that he is in possession for the last 12 years, openly, continuously,hostile and as owner to the knowledge of real owner. 

1. You should ask him to stop the digging work in your limits as he doesn't ask for permission before beginning the work.

2. If he doesn't stop the work send him a legal notice or make police complaint for trespassing and damaging the property.

3. If he still doesn't stop file suit for restraining him from entering in your property and stop every type of work on your property.
