Frequently Asked Questions

Which expenses increase the most?
Housing is the biggest shock. When one person moves out, both spouses effectively need their own housing — often at a higher combined cost than before.
Which expenses go down?
Food, dining, and shared entertainment costs typically halve. Some subscriptions and utilities also reduce slightly.
How can I close the budget gap?
Consider downsizing housing, adding a roommate, renegotiating insurance rates, reviewing subscriptions, or factoring the gap into alimony negotiations.
Should I negotiate alimony based on this?
Absolutely. Knowing your monthly shortfall gives you a concrete number to discuss with your attorney and helps courts understand your financial need.
