In dealing with separating and divorced families where child support i
s not being paid, clinicians, lawyers, mediators and judges are often
at a loss as to how they may intervene successfully. Although popular
beliefs abound regarding motivation for non-payment, we still have a p
oor understanding of the ways in which fathers rationalize a position
of partial or non-payment. The justifications given, both in literatur
e and in clinical practice, often are not supported by other relevant
data. The research undertaken in this exploratory qualitative study wa
s designed to develop a phenomenological understanding of fathers' dec
isions not to pay obligatory child support following separation/divorc
e. It is hoped that such an understanding will aid practitioners in id
entifying contributing difficulties and in developing constructive int
erventions. Although a specific sub-group of noncompliant fathers are
described in this report, thematic areas are identified which may be r
elevant to a broad range of fathers. In terms of expressed content the
se are: stated reasons for noncompliance, experiences and perceptions
of the legal system, role and identity, and personal goals and politic
al solutions. In addition, clinically relevant themes which emerged fr
om the analysis are: compliance/co-operation, conflation of the legal
system and the spouse, transformations in roles and identity, and the
need to be heard/supported. Implications for professional practice are
discussed.
