What is the test for quiet title and the statute of limitations?

Following closing arguments, the trial court took the matter under submission and subsequently issued a written ruling. On the statute of limitations, the court ruled as follows: "Defendant insists that plaintiff's claim to quiet title is barred by the statute of limitations. As defendant would have it, the statute began to run in 2011, when the romantic relationship ended, and had long expired by the filing of the complaint in January of 2018. However, the statute of limitations does not run against one in possession of land. [ Salazar v.
