The court and any person, in exercising functions under or in consequence of Parts II and III, shall have regard to the following general principles—
(a)that the institution of marriage is to be supported;
(b)that the parties to a marriage which may have broken down are to be encouraged to take all practicable steps, whether by marriage counselling or otherwise, to save the marriage;
(c)that a marriage which has irretrievably broken down and is being brought to an end should be brought to an end—
(i)with minimum distress to the parties and to the children affected;
(ii)with questions dealt with in a manner designed to promote as good a continuing relationship between the parties and any children affected as is possible in the circumstances; and
(iii)without costs being unreasonably incurred in connection with the procedures to be followed in bringing the marriage to an end; and
(d)that any risk to one of the parties to a marriage, and to any children, of violence from the other party should, so far as reasonably practicable, be removed or diminished.
