There are at least two separate issues here.
First, by "spouse support" I'm guessing you mean "alimony". The answer is yes, this CAN happen. Whether or not it DOES happen in any particular case depends a significant amount on how good each party's lawyers are.
The other issue is the "because of abuse" part. That's ammunition for your lawyer (see above) to get you a better deal in the divorce.
If you been separated from your spouse but did it because of abuse do you need legal documentation for that?
Depends if there is abuse in forms of verbal abuse, things such as yelling, threatening can be classified as abuse. If not than yes it is
99.9% of spouse abuse is caused by alcohol abuse.
Any form of spouse abuse is major, abuse is abuse and no one has any rite to abuse any one or anything.
It can affect a marriage in almost every possible way but it usually begins with negatively affecting communication such as arguments, isolating, lying about how much was consumed and generally pulling away from your spouse.
This is obviously violence. Unless done in self-defense it is abuse, but even then it is a most unsatisfactory state of affairs in a marriage. You should consider reporting the matter to the police.
* No, keeping a log or journal of an occasional disagreement on a spouse is not abuse, but it is strange behavior. Your partner may feel that you are abusive and is reading material and keeping the log or journal to prove to themselves and perhaps you that indeed you are verbally abusive (even if you are not.) It would be wise to communicate well with your spouse and get to the bottom of this problem. All the reading on verbal abuse and logs or journal entries will not fix anything that is wrong in the marriage. The only other possible reason for this behavior is if your spouse is a psychologist; psychiatrist or taking a psych course.
It could be considered abuse, if your spouse knows that his or her actions are causing you to be afraid or unhappy and they continue to act that way just to harm you.
Depends on the situation. Is there any adultry, abuse or have you moved out of the home or your spouse?
Yes.
it is entirely possible. just because nobody has seen it doesn't mean the abuse has not occurred. Doubting someone who complains of abuse is extremely dangerous. Any knowledge of abuse should be reported to the authorities
yes, because any crime is a violation of probation, so abuse is considered asault which is a crime.
