Deceased took defendant, his son, to a notary and there made and acknowledged written assignments of three mortgages he owned. He handed these assignments to defendant, saying "I give you these. Put them in the safety-deposit box." Defendant went away with the assignments which reappear only after the father's death; they were found in an envelope, marked with defendant's name in deceased's hand, in a safety-deposit box owned jointly by deceased and defendant. Deceased always retained possession and enjoyment of the actual mortgage instruments. Plaintiff, another son, claims these mortgages should be part of deceased's estate. The court held that a delivery of the written assignments was a good delivery of the choses so that defendant got title during the father's life. Jackman v. Jackman, 271 Mich. 585, 260 N. W. 769 (1935).
