So I googled the term to learn more, and it varies by state but…

Sounds like you need to

• be on the property for 2-30 years
• not hide that you’re using it
• have people think you actually own it
• be hostile in the take over (permission by owner negates this and disallows adverse posession)
• be using the land (living on, working on etc)
• legal owner must not be using the property.
• must be continuously using the property for the whole statutory period (2 to 30 years) or it resets

Edit: and in Texas the period is 10y
