Where the wife willingly leaves her husband to live with another man she will be barred of her action to demand her dower unless her husband willingly takes her back, in which case she will be restored to her right.
Dower may be barred by a wife joining in a conveyance or other instrument dealing with the land, or by a separate instrument. The mere joining of the wife in the conveyance is sufficient, and it is not necessary that the husband should be a party to a special instrument barring dower. But a bar of dower only takes effect for the purpose for which the instrument is intended. For instance, a bar of dower in a mortgage only bars the dower for the purpose of the mortgage, and the wife still has dower in the equity of redemption remaining to her husband. If the land is sold under a mortgage or under any legal process for its collection, the wife of the mortgagor will be entitled to dower in any surplus of the purchase money arising from such sale after satisfying the claim of the mortgagee,
