Relationships with in-laws play an important role in individuals' lives, but we do not know how these ties are formed. We considered two pathways through which early relationships with mothers-in-laws may affect subsequent in-law relationship qualities: a) dimensions of the early relationship and, b) beliefs and expectations of the future relationship. Sixty men and women engaged to be married and their mothers (N = 240) completed interviews prior to, and 6 to 8 months following the wedding. Measures at Time 1 assessed three dimensions of the in-law relationship: a) behavioral (contact by phone, in person), b) emotional (positive and negative relationship qualities), and c) cognitive (knowledge about the other person). Participants also described positive and negative expectations of their future tie. Multilevel models revealed that dimensions of the tie prior to the marriage were associated with post-wedding in-law relationship qualities. When the parties had individual contact with one another and positive feelings before the wedding, ties were stronger following the wedding. Data from open-ended descriptions of negative expectations obtained before the wedding predicted negative relationship qualities after the wedding. Husbands, wives, and mothers-in-law showed similar patterns with regard to relationship qualities. Discussion focuses on the role of early emotional qualities of the in-law tie for subsequent in-law relationships.
