Thanks for posting this. I actually have concerns about squatters rights for a piece of property that I may ineherit atleast 50% of sometime in the future. A neighbor to that property has been aloud to run a drain pipe onto our property for many years without being legally properly challenged for it. So it is an issue in the back of my mind.
Talk to whomever owns the property now and see what they say. The owner of the pipe may have been given permission. Just do something now.
If you know where the property line is, terminate the drain.
Waiting will only make it more difficult to deal with.
Report it to your city code enforcement and see what they say, and you can probably do it online if your not where the property is.....if it’s a violation they live to fine people and put Leins on property......if I had an hour I’d tell you how I know that 😏
Beware of that. The claim of “adversarial possession” can be used to extinguish your property rights. Use the property for something, cut the grass, park a car build a small shed, but actively use it.
Talk to a lawyer before you do anything.
If you say anything to the neighbor, they might launch legal proceedings. It is possible if you quietly make alterations to things, without him knowing, he will not be able to claim you allowed the pipe without issues, and you can claim you were still asserting control over the property.
Don’t make a move if you do not know how it will play out legally.
Challenge that neighbor IMMEDIATELY. Be nice and see if you can get them to sign an agreement even for a nominal fee for the drainpipe. That would at least preserve your rights. If you allow that drain pipe to stay on your property unchallenged for several years they will acquire what’s called a prescriptive easement which is like adverse possession. ie they will acquire the right to keep that drain pipe on your property permanently whether you like it or not.
If you sit on your rights, you will lose them.
Why not start by asking the person that now owns the place if they gave permission to the neighbor for the drainage?
It's always better to start knowing the facts, and your own statement indicates that permission has been given; i.e. aloud = allowed, and allowed = permission, either verbal, written or consent over time by lack of any contrary action.
Thoroughly plow the drain pipe under in a tragic landscaping
accident and apologize profusely.
