OK; let's get basic here. What is a Living Trust? It's a different way of doing one's Will and (eventually) transferring one's estate to heirs. It's partly a way of satisfying title companies.
If Nils had a Will and then died, Lars as Executor would file the Will, give certain required notices, Inventory the assets, pay the taxes and other costs, and finally transfer the assets to the heirs. The Will gives him the authority to do all this, but the world doesn't recognize his authority until he goes to Court, files the Will and the proper pleadings to start a probate, and is recognized by signature of the Judge or Commissioner there. The Will and Lars's appointment as Executor are then part of the public record. So when Lars signs and records a deed of Nils's residence to whomever has inherited it under the Will, or to someone who buys it from Nils's estate, title companies will see in the record not only the deed, but Lars's appointment as Executor, and willingly issue title insurance to the new owner.
A Living Trust is a different way of doing all this. Nils can sign a Living Trust Agreement that looks kind of like a Will. Then, if things are done right, Nils will transfer title to his assets to the Trustee of the Living Trust (now, while Nils is living). The Trustee thus has title. If Nils dies, the Trustee named in the Living Trust Agreement still has that title, and may transfer it to their heirs or sell it as part of the estate process. There is no Court filing, no probate. Avoiding the probate process can save estate costs, particularly with properties in certain states like California.
