<human>: I bought a house that was built in 1960's in September of last year.  We always assumed the land ended at the fence that was currently installed.  We are installing a new fence/garage and just got a new survey completed.  Apparently we own 20' past where the fence is currently placed into my neighbor's yard.

I do not know how long Neighbor has lived there, I do know the house I bought was empty for about a year or so before I bought it and I can assumed he maintained what we now know is my yard.

I am at work and have not talked to Neighbor but my wife said he has seen the new yard stakes.  How do I approach this issue?  Is it legally my property or does he have a claim to it because he has maintained it for a while?  Is there any way we can split the difference with no cash changing hands?  I honestly don't want all the land so I want to solve this smoothly since I plan on living here for a long time.

Can you condense the text into three sentences or less?
<bot>: Land surveyed, we own more then we thought, does my neighbor have any claim to the yard we just learned we owned?
