What is adverse possession?

Adverse possession lets someone gain legal ownership of land by occupying it openly for a set period.

Why it matters

It rewards long, obvious, hostile use and can resolve unclear boundary situations.

Common confusion

It is not “squatting” you can do secretly — the use must be open, continuous, and notorious.

Frequently Asked Questions

How long must I occupy the land?

The period varies by state, often 5 to 20 years of continuous use.

Does paying taxes help?

In many states, paying taxes on the land strengthens an adverse possession claim.

Can I lose land I own this way?

Yes, if a neighbor openly uses part of it long enough and you never object.
