HRI/GEN/1/Rev.9 (Vol. I) 23. States are required to treat men and women equally in regard to marriage in accordance with article 23, which has been elaborated further by general comment No. 19 (1990). Men and women have the right to enter into marriage only with their free and full consent, and States have an obligation to protect the enjoyment of this right on an equal basis. Many factors may prevent women from being able to make the decision to marry freely. One factor relates to the minimum age for marriage. That age should be set by the State on the basis of equal criteria for men and women. These criteria should ensure women’s capacity to make an informed and uncoerced decision. A second factor in some States may be that either by statutory or customary law a guardian, who is generally male, consents to the marriage instead of the woman herself, thereby preventing women from exercising a free choice. 24. Another factor that may affect women’s right to marry only when they have given free and full consent is the existence of social attitudes which tend to marginalize women victims of rape and put pressure on them to agree to marriage. A woman’s free and full consent to marriage may also be undermined by laws which allow the rapist to have his criminal responsibility extinguished or mitigated if he marries the victim. States parties should indicate whether marrying the victim extinguishes or mitigates criminal responsibility and, in the case in which the victim is a minor, whether the rape reduces the marriageable age of the victim, particularly in societies where rape victims have to endure marginalization from society. A different aspect of the right to marry may be affected when States impose restrictions on remarriage by women that are not imposed on men. Also, the right to choose one’s spouse may be restricted by laws or practices that prevent the marriage of a woman of a particular religion to a man who professes no religion or a different religion. States should provide information on these laws and practices and on the measures taken to abolish the laws and eradicate the practices which undermine the right of women to marry only when they have given free and full consent. It should also be noted that equality of treatment with regard to the right to marry implies that polygamy is incompatible with this principle. Polygamy violates the dignity of women. It is an inadmissible discrimination against women. Consequently, it should be definitely abolished wherever it continues to exist. 25. To fulfil their obligations under article 23, paragraph 4, States parties must ensure that the matrimonial regime contains equal rights and obligations for both spouses with regard to the custody and care of children, the children’s religious and moral education, the capacity to transmit to children the parent’s nationality, and the ownership or administration of property,whether common property or property in the sole ownership of either spouse. States parties should review their legislation to ensure that married women have equal rights in regard to the ownership and administration of such property, where necessary. Also, States parties should ensure that no sex-based discrimination occurs in respect of the acquisition or loss of nationality by reason of marriage, of residence rights, and of the right of each spouse to retain the use of his or her original family name or to participate on an equal basis in the choice of a new family name. Equality during marriage implies that husband and wife should participate equally in responsibility and authority within the family. 26. States parties must also ensure equality in regard to the dissolution of marriage, which excludes the possibility of repudiation. The grounds for divorce and annulment should be the same for men and women, as well as decisions with regard to property distribution, alimony and the custody of children. Determination of the need to maintain contact between children and the non-custodial parent should be based on equal considerations. Women should also have equal inheritance rights to those of men when the dissolution of marriage is caused by the death of one of the spouses. 27. In giving effect to recognition of the family in the context of article 23, it is important to accept the concept of the various forms of family, including unmarried couples and their children and
