1) The care taker has been given 30 sq.yards of land through registered Deed, that is all he will have right over.
2) If the tenant has been paying rent and if there is a rent agreement and if you want to evict him you can ask him to vacate. As he has already a piece of land allotted to him that should be a reasonable arrangement.
3) However if the tenant has been occupying the land/house without any rent agreement in place there is a possibility of him getting the benefit of adverse possession and title to the property thereof.
Let me quote what adverse possession means:Title to land is acquired by adverse possession as a result of the lapse of the Statute of Limitations for Ejectment, which bars the commencement of a lawsuit by the true owner to recover possession of the land. Adverse possession depends upon the intent of the occupant to claim and hold real property in opposition to all the world and the demonstration of this intention by visible and hostile possession of the land so that the owner is or should be aware that adverse claims are being made.
The legal theory underlying the vesting of title by adverse possession is that title to land must be certain. Since the owner has, by his or her own fault and neglect, failed to protect the land against the hostile actions of the adverse possessor, an adverse possessor who has treated the land as his or her own for a significant period of time is recognized as its owner.
Title by adverse possession may be acquired against any person or corporation not excepted by statute. Property held by the federal government, a state, or a Municipal Corporation cannot be taken by adverse possession. As long as the property has a public use, as with a highway or school property, its ownership cannot be lost through adverse possession.
Elements In order that adverse possession ripen into legal title, nonpermissive use by the adverse claimant that is actual, open and notorious, exclusive, hostile, and continuous for the statutory period must be established. All of these elements must coexist if title is to be acquired by adverse possession. The character, location, present state of the land, and the uses to which it is put are evaluated in each case. The adverse claimant has the burden of proving each element by a preponderance of the evidence.
