Depending on your state, the income that you earn as a spouse after the date of your separation becomes separate property. But the money you earned prior to the date of separation that wasn't paid until after your separation still remains marital property. Any shared accounts have to be closed, and all other joint property or finances should be divided if you wish to completely separate yourself financially. However, the terms of your separation agreement might stipulate that things like insurance, expenses, and payments for alimony be divided in a specific way. The more you include in your separation agreement based on your personal preferences with the spouse from whom you are separating, the clearer this aspect of your separation will be.
