It depends on the state you live in! Most often, if both people have established residency and get mail delivered to that address, pay bills together or are responsible for bills, and have a financial obligation or interest to the residence - then NO, no spouse can lock the other spouse out. One can volunteer to leave, or police may ask one party to leave for a specified time (if they get involved), but the right to the residence still remains. The judge can remove a party from the residence, but that would be because of a court order/restraining order/protective order.
Then the house needs to be sold.
Depends on the will
Yes, it is possible for one spouse to itemize deductions while the other spouse takes the standard deduction when filing jointly.
Not unless the spouse signed the debt paperwork. However, will they chase one spouse to get to the other spouse, yes they will.
Yes, a married couple filing separately can choose to itemize deductions for one spouse and take the standard deduction for the other spouse.
Only if the other spouse is given keys to said locks. With two people who are legally married, one cannot lock out or evict the other without going through the court system in some fashion. They must file for legal separation or one spouse has to have broken the law in some way (resulting in, for example, a restraining order or involuntary psychiatric hold). Even if the spouse wanting to lock the other out is the owner of the house and the other is not, it doesn't matter, because they are said to have an "interest" in the property due to the marriage.

Yes, one spouse can file for divorce without the other spouse's consent.

Not directly. The spouse that receives the inheritance can determine what is done with that inheritance. There is no automatic right for the other spouse to receive any of it.
I think that the other spouse is untitled to half of what the two had together, which includes the amount of money.
