D Velusamy Vs D Patchaiammal, CRIMINAL APPEAL NOS. 2028-2029 OF 2010

we may point out that the expression `domestic relationship' includes not only the relationship of marriage but also a relationship `in the nature of marriage'. The question, therefore, arises as to what is the meaning of the expression `a relationship in the nature of marriage'. Unfortunately this expression has not been defined in the Act. Since there is no direct decision of this Court on the interpretation of this expression we think it necessary to interpret it because a large number of cases will be coming up before the Courts in our country on this point, and hence an authoritative decision is required…..
In our opinion a `relationship in the nature of marriage' is akin to a common law marriage. Common law marriages require that although not being formally married :-
(a) The couple must hold themselves out to society as being akin to spouses.
(b) They must be of legal age to marry.
(c) They must be otherwise qualified to enter into a legal marriage, including being unmarried.
(d) They must have voluntarily cohabited and held themselves out to the world as being akin to spouses for a significant period of time.(see `Common Law Marriage' in Wikipedia on Google)
In our opinion a `relationship in the nature of marriage' under the 2005 Act must also fulfill the above requirements, and in addition the parties must have lived together in a `shared household' as defined in Section 2(s) of the Act. Merely spending weekends together or a one night stand would not make it a `domestic relationship'….
In our opinion not all live in relationships will amount to a relationship in the nature of marriag8e to get the benefit of the Act of 2005.To get such benefit the conditions mentioned by us above must be satisfied, No doubt the view we are taking would exclude many women who have had a live in relationship from the benefit of the 2005 Act, but then it is not for this Court to legislate or amend the law. Parliament has used the expression `relationship in the nature of marriage' and not `live in relationship'. The Court in the grab of interpretation cannot change the language of the statute.
