In Howard v. Shaw, 10 Wash. 151, 38 P. 746 (1894), the appellant claimed he was entitled to rely on county records which demonstrated that a third party was the owner of a mortgage, and he therefore assumed that she was the owner even though she had assigned it; the respondent asserted that the law did not require or permit the assignment of the mortgage to be recorded. The Court found that assignments of mortgages are not within the recording acts unless there are express provisions to that effect. Id. at 155.

Id. 199. And this is all there is upon the subject.
