A person park his car on my plot

What exactly will you do if he parks his car?

No contract is created as consent is necessary for a valid contract. As Mr.X will not give you consent , a valid contract doesnt exist.

If Mr.X is infringing your right to enjoyment of peaceful property and unlawfully using your land for any purpose then it creates a civil liablilty against Mr.X.

I believe you should first sent him a cease & desist legal notice to Mr.x asking him to not use your property and to stop from interfering with your possession of the land or else civil suit will be initiated against him.

Then if Mr.X still does not cease & desist after receipt of your legal notice, you can go ahead with a civil suit praying for Permanent injunction as relief and also ask for ad interim injunction and a temporary injunction against Mr.x.

Hope this clears your doubts.

sir if mr x give his consent/acceptance to this propsal then will it become valid ???

and what is the consideration here for both parties ???

Mr.Sankliya , if you wish to give your place for parking to Mr.x then you could do so by giving him a license in return for some consideration.That consideration is generally money.

However if you do not then it is another matter.

Parking rights may or may not be transferable.
