What is the ruling when a wife claims her husband gifted her a house in his possession, or that she purchased it from him, and the husband denies this?

Primary text

The statement of the husband is accepted, provided he takes an oath. This is based on the principle that the statement of the denier is accepted with his oath. If both parties present evidence, the evidence of the wife takes precedence because her claim asserts an addition that was hidden from the evidence of the husband.
