Double deck or decker marriage has some identifiable resultant legal effects. The effects have bearing on both systems of law wherein the marriages were conducted. The following are the consequences of a double deck marriage:
a. Status of the marriage: Under the double deck marriage, the question arises as to whether the parties married should be monogamous, polygamous or both simultaneously. According to the conversion theory, the customary law marriage is converted by the statutory marriage, consequently the parties’ status should be monogamous. However, the co-existence theory contends that the two marriages co-exist, therefore status of the parties is monogamous, but potentially polygamous. This position is however ambiguous in the light of the provision of Section 33 and Section 47 of the Marriage Act.
b. Ownership of Matrimonial Property: Under custom, the wife requires the husband consent to deal with her own property or at the least holds him in coincidence in order to deal with her own property or her private chattel. This is in consonance with the tradition that categorizes a wife as part of husband’s property. This contradicts Sections 2 and 3 of the Married Women Property Act and is repugnant to natural justice, equity and good conscience. Couples married under the statute do not require each other’s consent to any act done on the other’s property. The conversion theorists argue that what applies statutorily would apply and be the effect, but the co-existence theories hold a contrary view that both systems would apply simultaneously. Under both systems the husband should maintain his wife during the subsistence of the marriage.
c. Jurisdiction of the court: The conversion theorists opine that since the original customary marriage has been converted into a monogamous marriage, the divorce petition must only be presented in the High Court which has exclusive jurisdiction to dissolve statutory marriage. The co-existence theorists have the view that a court must first determine the question of jurisdiction. Therefore, where the petition is presented first in the customary court, it would have jurisdiction to dissolve only the initial customary marriage, thus leaving the statutory marriage to be dissolved by the High Court.
d. Dissolution of marriage: The grounds for dissolution of marriage under the two systems differs. While adultery and incompatibility are facts evidencing the irretrievable breakdown of the marriage under the Act, it is only a ground available and exclusively so, to the customary law husband as against the wife. The coversionists posit that both spouses can get a dissolution on proof of adultery and its intolerability under the Act while the co-existence theorists insist that there is a serial dissolution of the double deck marriage. This means that inspite of the ruling of the court dissolving the marriage, the customary regime would still be applicable to the couple.
e. Bride price: The dissolution of a marriage under customary law is marked by the return of the bride price. The coversionists state that the issue of bride price does not come into play as they uphold the view that the original customary law marriage is terminated by its conversion to the later statutory marriage. The co-existence theorists however, believe that the married woman would still be regarded as a wife under customary law until the bride price is refunded.
f. Death: Under the Act, death ordinarily, terminates a marriage, but under the customary law, marriage does not ipso facto terminate the union, especially where the husband dies before the wife. The co-existence theorists argue that the marriage under the Act would be terminated but however, obligations will have to be fulfilled for the termination of the customary marriage in a situation where the husband predeceased the wife as the woman still remains and maintains her status as wife in the man’s family until she either remarries or returns the bride price to put an end to the customary marriage. For the coversionists, the status of the double deck married couples comes to an end on the death of either spouse.
