You are the "spouse" until you are no longer legally married.
While the divorce is pending, the spouse is still the spouse, and the legal status does not change. On the day that the divorce is granted, the spouse is no longer the spouse, and reverts to non-related.
The spouse is not responsible and should not have this on her credit. But the estate of the deceased will still be responsible for the debt.
It means you should leave them.
If the debt is in writing and you only have a verbal clearance of it, then I would suggest that the debt is still owed. The spouse might not have the authority to write off the debt. You need to get the spouse or the person owed to sign a document to the effect that the debt is no longer outstanding.
If you own your car or house and are no longer making payments, should you still have insurance on them? Explain why or why not.
Should no longer have if you are.
Yes, if the child is still a minor or is no longer a minor but is severely handicapped.
It depends on the law in your jurisdiction. Some states still have "alienation of affection" laws but they are very difficult to prosecute. However, although its easier to blame the spouse's lover, it should be understood that it is your spouse who owes you fidelity. A third party should not take the blame.
if you mean in value? no they are no longer linked, they USE to be but no longer are, but they should still be.
Yes and no. You should do everything you can to try to locate the spouse you are trying to get a divorce from. But if you cannot find him or her then you can still get a divorce. Known as a default divorce, the court will grant the divorce once you should that service was not possible. You should not wait or assume that it is not possible without the other spouse because that is simply not the case.
Nothing. It is strange that your spouse still communicates with the person she had an affair with, but aslong as it is just words and not actions, it is still acceptable.
