I suggest you speak with a divorce attorney for professional advice on how to deal with this manner and what legal actions you can take about living arrangements and beginning the divorce process.
To get a divorce without moving out of your house, you will need to get your spouse to move out, or reach an agreement about continuing to live (separately) in the home.
You get a divorce and leave the house, before it is to late !
No, not unless you put your spouse on the deed.
Then go to the court house!
You need to talk to a divorce lawyer about that.
If both of you signed the deed to the house you are entitled to half. However if your spouse owned the house before you were married it belongs to him.
In what circumstances? If the spouse dies? If there is a divorce? The laws vary from state to state and based on the situation.
In a divorce, it could happen. Have her sign a prenup.
The advantage would be for the spouse if you reside in a community property state where survivorship goes to the spouse should a death occur and property is divided 50/50% in cases of divorce.
Depends on who owns the house, how the ownership of the house has been allocated (per the court) and if you have the consent of the spouse (if they are deemed to have partial ownership of the home).
You need to clarify the state.
To get a divorce, all you have to do is not spend any time with that person for a while and eventually the person with notify you that they want a divorce. Then the next time you see that person they start to leave the town they live at.
