Unjust enrichment is mostly supposed to be if you knew they were doing work at your place when they weren't supposed to be.
Say your neighbor pays to redo their backyard. Install a big outdoor kitchen, install a fancy pool with a water slide, etc.
They mix up which yard is which. You see them come into your yard and start digging. You think "maybe I should stop them..." but don't. Instead, you let them build out a $100,000 backyard setup in your yard over the next week.
You could have stopped them. You were there. The construction workers saw you were home and saw you leave and come back several times during the week. There's no doubt you were aware of the unpaid construction work being done. Instead, you waited until all the work was completed.
In this case there's practically little way this owner, who lived over 2,000mi away from the property, would have reasonably known this construction was happening. This is why that case was thrown out.
