Bava Batra 49: Can a Wife Be forced to Sell Land to Her Husband?
A husband cannot establish a presumption of ownership regarding his wife's property - nor a wife regarding her husband's. Which makes sense given the usual terms of rights in marriage, but even if he has foresworn those rights. Also, if there's proof of a sale, then he would take ownership of her property -- unless she then protests (possibly in contrast to Rav Huna and valid sales under duress). The ketubah itself can stipulate ownership too.
