Adverse possession of house and adjacent land.

Sir, I have a house and some free land adjacent of my house. I live there more than 12 years. It is 6 decimal plot. I bought 5 decimal from the previous owner and 1 decimal was in my possession for more than 12 years because there was no actual owner of that land at that time. I was paying land tax of 6 decimal for more than 12 years. Now my neighbour doing a court case claiming that he has also some land in my property. My question is that here adverse possession would be applicable or not. Because I am paying land tax and municipality tax for this property more than 12 years.
Now my neighbour want land from my property. If adverse possesion applicable in my case I would like to know my tax receipts i.e. land and municipality tax receipts can be used as proof of my adverse possession.
