It often is helpful to prepare a diary or narrative describing the marriage, including:
a. Each parties' monetary and non-monetary contributions,
b. Child rearing/care activities of each parent,
c. Marriage history/timeline,
d. Problems and concerns throughout the marriage
e. History of criminal, legal or medical issues during the marriage
f. Employment histories throughout the marriage.
