In what circumstances have the courts found that a joint owner of a homestead can transfer interest in the homestead without the consent of the wife?

It would seem that all three of these cases were decided on the ground of unconscionability rather than estoppel, but again, in the final result, a transfer of interest in a homestead was not held to be null and void where the wife had consented although the provisions of the Homesteads Act as to the formalities (required before registration of such a document could take place) were not observed. It is to be noted that Baldwin v. Rhinhart, supra, appears to be the only case where the wife was a joint owner and signed the document in question as joint owner.
