Under Colorado law, the time limit for adverse possession is 18 years. Colo Stat., Section 38-41-101. The time that the prior owners had the properties can be added to the times that you and your neighbor have been there. That means that your starting point may be to try to figure out when the shed was built - it's entirely possible that the neighbor acquired title by adverse possession before you even bought the land.
If the shed was built on or after July 1, 1990, the statute requires that he have a reasonable good faith belief that he owned that portion of the land before he could acquire title by adverse possession. Since you now have a survey
, that's impossible to establish. Another option is to simply give him permission to have the shed there. Legally, adverse possession is without the owner's permission. If you had something in writing stating that he could keep the shed there until further notice, that would also stop him from claiming title - as long as it hasn't been 18 years yet.
That means that it's probably necessary to talk to the prior owners to find out when the shed was erected. You could also see if there is anyone in the area who has lived there long enough to remember when it was built, if you can't find the prior owners. If the neighbor got permits to build the barn, then you could also check with the city.
