Apartments are cheaper than houses, but paying for both an apartment and a house is the most expensive choice of all!
1. You still owe the mortgage payments (you may be paying for your spouse to live in the house).
2. In addition to paying for the costs at the marital home, you may have your own costs after moving out (rent, utilities, etc.)
3. You may impair your claim for spousal support by decreasing your expenses.
4. You may harm your defenses against paying spousal support – you reduce your needs/expenses which is a determining factor for support or reducing support.
5. Leaving the home removes a potential bargaining chip in negotiations.
6. Getting evidence which may be in the house and you now are not may be difficult.
7. Sets date of separation for valuation purposes.
8. Typically you cannot return to the residence after separation. Although this may be an emotionally difficult time, it is best to consult a lawyer specializing in family law before moving out of the marital home.
