Tower vs landowner

No, the presence of a mobile tower on your land with a rent agreement unlikely qualifies for adverse possession by the tower company. Here's why:

Adverse Possession Requirements:

Continuous and Uninterrupted Possession: The company needs to show they occupied the land exclusively for a specific period (varies by jurisdiction, but typically 10-20 years). A rent agreement acknowledges your ownership and contradicts this claim.

Hostile Possession: Occupancy must be against your wishes. Paying rent signifies they have your permission.

Open and Notorious Possession: The company's use of the land must be evident and known to you. This is likely met, but the other factors outweigh it.

Payment of Taxes (in some jurisdictions): Some areas require the adverse possessor to pay property taxes. A renter wouldn't typically do this.

The Lease Agreement Strengthens Your Case:

The 2021 lease agreement reaffirms your ownership and their status as a tenant. It resets the clock on adverse possession, meaning the 12 years before 2021 wouldn't count.

You have a valid lease agreement with the them, hence there is no question of their possession of the land will be adverse to you.
