Hi - my name is XXXXX XXXXX I'm a Bankruptcy litigation attorney here to assist you.
In a Chapter 7, your bankruptcy estate (property, money, etc.) is established on the day that the bankruptcy petition is filed and consists of everything the debtor owns as of that day.
However, bankruptcy courts have held that a tax refund, or a portion of it, can be an asset, even though you may not receive it until well after the bankruptcy petition has been filed. Most courts divide the tax refund in proportion to the point in the tax year when the case is filed. For example, if you filed a bankruptcy petition on July 1, 2011, halfway through the year, 50% of your tax refund can become property of your bankruptcy estate. Obviously, if you file later in the year, that proportion will be greater.
The bankruptcy is completed after the discharge when the case is dismissed and closed. This usually takes a few months after the proof of claim deadline expires.
You can get married wherever you want as that has nothing to do with your Chapter 7 - the spouse's income has nothing to do with your bankruptcy. Also, you can sell your house whenever you want. You'll just have to get the court's permission to sell the asset if you do so during bankruptcy. If you wait until the bankruptcy is closed, you can sell it any time without permission from anyone.
