Willard v. Willard was a United States Supreme Court case that dealt with the issue of a wife's right to her husband's property. The case involved a dispute between a husband and wife, both named Willard, over the ownership of a piece of property. The husband had purchased the property prior to their marriage, and the wife argued that she had a right to the property as part of her marital rights. The Supreme Court ultimately ruled in favor of the husband, finding that the wife had no right to the property as it was purchased prior to the marriage. The Court held that the wife had no right to the property, as it was purchased prior to the marriage and was not part of the marital estate. The Court also noted that the wife had no right to the property as she had not contributed to its purchase. This case established the precedent that a wife has no right to her husband's property unless it is part of the marital estate.

In Willard v. Willard, the Supreme Court was asked to decide whether a husband had the right to revoke his wife's power of attorney over her separate property. The majority opinion held that he did not have this right and that it could only be revoked by an act of Congress or a court order. However, Justice Field dissented from this decision and argued that since marriage is considered a contract between two parties, then either party should have the ability to revoke any powers granted in such contracts without outside interference. He further stated that if one spouse has been given control over another’s property through an agreement made during marriage, then they should also be able to take away those rights at their own discretion as long as it does not violate public policy or morals. In conclusion, Justice Field believed that husbands should have the same authority when revoking their wives' power of attorney over her separate property as they would with any other contractual arrangement entered into during marriage.
