This article tackles the issue of marital homogamy in the Czech Republic using paired-data gather in 2005 on a representative sample of people aged 20-40. The aim is to find an answer to the question whether homogamy or heterogamy has any practical meaning for people who live either in marriage or in cohabitation and explore the differences in opinions with regard to marriage, childcare, gender roles and the reconciliation of family and paid work. We hypothesize that heterogamous couples will be more distant in their attitudes than homogamous couples. The results point out that the homogamy and partners closeness in answers are not related. Few explanations are offered in the end as a possible answer to why the working hypothesis was rejected.
