My neighbor is a squatter in his uncle's condo and is claiming "adverse possession" of the condo unit. I was not familiar with this so I have been reading up on the statutes. Is this legal and does he have a claim on the unit?? The condo association has threatened him with eviction/tow of vehicle like they do other units that have been late or behind in maintenance fees. This just fueled his fire to claim some type of "squatter's rights." I find that I'm really not grasping what the statutes are all about (not a lawyer at all) but very confused about what this "adverse possession" means regarding a condo unit.The "squatter" has lived in the condo unit for 6 years without any signed agreement with the condo association or his uncle. And has paid maintenance once within the last 18 months.
