For all civil injuries committed by a married woman, damages may be recovered from her alone, and her husband shall not be responsible therefor except in cases where he would be jointly responsible with her if the marriage did not exist [§3396.] This statute abrogates the rule of the common law, making a husband responsible for civil injuries committed by his wife. The common law presumption that criminal acts done in the presence of the husband were by compulsion, is still recognized in this State but may be overcome by proof to the contrary. [Sidenote: Conveyances to each other valid.] [Sidenote: Conveyances to third parties.] A conveyance, transfer or lien executed by either husband or wife, to or in favor of the other shall be valid to the same extent as between other persons [§3397.] When the rights of creditors might be prejudiced by transfers of property between husband and wife, such transactions will be closely scrutinized, and the utmost good faith must plainly appear, but where no fraudulent intention is shown they will be upheld if based upon an adequate consideration. If a conveyance is made by the husband to the wife when the husband is largely indebted and insolvent, such conveyance is presumptively fraudulent, but a conveyance to a wife in payment of a valid claim, even though made at a time when the husband is largely indebted to others, will not be considered fraudulent the wife having the same right as other creditors to obtain payment. All contracts between husband and wife where no other consideration appears than an agreement to perform some duty already incumbent upon the parties, because of their relations as husband and wife, are against public policy, and will not be enforced in law. Such, for example, as a promise by the husband to pay money to the wife to induce her to live with him, when she has no legal ground for not living with him; or an agreement to allow the husband to obtain a divorce when he has no legal cause for divorce, or a conveyance of property in consideration of future care and support because the husband is growing old; or a contract between husband and wife by which the husband agrees to pay the wife at stated intervals, sums of money, in consideration of the faithful performance by the wife of the obligations incident to the marriage relation. But our courts have held that exempt property may be transferred by the husband to the wife without any consideration; that a deed from husband to wife in consideration of a dismissal by the latter, of a proceeding for divorce, is valid; that a contract between husband and wife by which the wife, for a consideration, after a decree of divorce, agrees to release all her dower interest in the real estate of the husband, is binding. Voluntary conveyances, in favor of third parties, by a man or woman in contemplation of marriage, and with the evident intention of defeating the marital rights of the other party, in
