After a couple separates but before their divorce is final, it is expected that the spouse who occupies the former marital residence will pay the mortgage, home equity loan or line of credit, taxes, insurance, and utilities for the home. There may be a requirement that the spouse who is not residing in the home will have to pay a portion of those expenses. The amount the spouse who is not residing in the home would have to pay is a function of the incomes of the parties and is calculated as part of a broader spousal support calculation.
