By an act approved Feb. 24, 1891, cause 6, as given above, was amended so as to read as follows: "Personal indignities rendering life burdensome." _Limited Divorce._ There is no limited divorce in Washington. _Special Provisions for Defence._ Whenever a petition for divorce remains undefended, it shall be the duty of the prosecuting attorney to resist such petition, except where the attorney for the petitioner is a partner of or keeps his office with, such prosecuting attorney, in which case the court shall appoint an attorney to resist the petition. _Temporary Alimony._ During the pendency of an action for divorce, the court may make such orders relative to the expenses of the suit as will insure to the wife an efficient preparation of her case, and a fair and impartial trial thereof. _Permanent Alimony._ In granting a divorce the court shall make such disposition of the property of the parties as shall appear just and equitable, having regard to the respective merits of the parties, and to the condition in which they will be left by such division and to the party through whom the property was acquired, and to the burdens imposed upon it for the benefit of the children. _Refusal of Divorce._ No divorce shall be granted in case of adultery, if the offense has been forgiven by the petitioner, or on the ground of force or fraud, if there has been subsequent voluntary cohabitation of the parties. In case of adultery the action must be commenced within one year after petitioner shall have knowledge of the act. _Answer or Cross-complaint._ The defendant may, in addition to the answer, file a cross complaint for divorce, and the court may grant a divorce in favor of either party. _Change of Name After Divorce._ In granting a divorce, the court may, for just and reasonable cause, change the name of the wife, who shall thereafter be known and called by such name as the court shall in its order or decree appoint. _Trial by Jury._ Practice in civil actions govern all proceedings in the trial of actions for divorce, except that trial by jury is dispensed with. _No Divorce on Confession._ When the defendant does not answer or, answering, admits the allegations in the petition, the court shall require proof before granting the divorce. _Custody of Children._ On granting a decree, the court shall make provision for the guardianship, custody, support and education of the minor children of the marriage.
