In my community-property state, for example, a reasonable settlement might look like this:
Assets acquired during the marriage, including retirement funds, split 50:50. (Formulas for splitting defined benefit pensions are a little different).
Debts split 50:50
Alimony to the lower earning spouse for 1/2 the number of years married (may not apply if her income is good and she never mommy-tracked her job).
Child support based on a formula and influenced by % custody.
