The inserction of the middle and upper class woman into the labor market, her search for professional realization and financial independency definitely transformed the traditional work division among couples. The woman`s money in the contemporary marriage is an essential mark that led to changes in the way couples live together since the half of the 20th century. And that`s why an analysis of the financial decision making process in couples is so important to give us information about the power relations, differences and individual characteristics of regular wife and husband. Specially in a just-married couple, objective of our research, where the development and negotiation of these behaviors begins, taking into account each side`s familiar values. To understand the consequence of these changes in the husband/wife relation is key to understand marriage itself. And that subject lacks of studies here in Brazil. This research aims to understand these woman`s money impact in the contemporary marriage. How the couple defines its rules, how they are accepted and questioned upon. The method used consisted of an interview of twelve women that had recently got into living together with someone (from 6 months to 3 years), not necessarily through marriage. To be eligible for the interview both husband and wife had to be on their first marriage, both working, no kids and be part of the middle class or above. Their speeches revealed that women see the remunerated work a way of acquiring autonomy in their decisions and a possibility to develop personal hobbies. Besides that, the majority of the interviewed women says that she is organized with their own money, being, most of the times, her who controls and plans the finances of the couple. In fact, their autonomy is more linked to assume its planning than to simply earn it. That was noticed, since only two of the interviewed women delegate to their husbands the management of their money, what causes them to lose priority on how to decide the way money is going to be spent.
