T v T (shared residence) [2010] EWCA Civ 1366, [2010] All ER (D) 04 (Dec)
There was no universal solution for cases dealing with non-traditional families. They depended on their individual features and were shaped by the personalities, strengths and weaknesses of the individual human beings involved.
The discretion entrusted to the individual trial judge was, accordingly, considerable and the task of an appellant seeking to show that he or she had gone sufficiently wrong in the exercise of it to justify an appeal court interfering was correspondingly burdensome.
