This is what the home site says:
"Divorce from bed and board is a fault-based action, usually brought by an injured spouse to get the court to order the other spouse out of the residence. If brought in conjunction with other claims (custody, child support, distribution of property), a judicially ordered separation pursuant to the prayer for divorce from bed and board establishes the separation required for those other actions. The complaint for divorce from bed and board must be verified and it must contain the required allegations of residency.
Only the injured party may apply for a divorce from bed and board. The complainant seeking a divorce from bed and board must establish at least one of the six fault grounds enumerated in the statute: abandonment, malicious turning out of doors, cruel or barbarous treatment, indignities, excessive use of alcohol or drugs rendering the condition of the other spouse intolerable, or adultery. Further, the complainant must allege that he or she did not provoke the other spouse’s misconduct. The right to jury trial in an action for divorce from bed and board is governed by the statutory provision permitting a jury to make the factual findings on issues of fault."
What this means is that if she can prove one of the six faults listed required then she can have you move from the marital residence. The bills, mortgage would be the same until arrangements can be made to change those. Even though you have no legal obligation after this to finacially provide for her, if your name is still on the bills, you are still responsible. Yes, you can have your attorney file divorce from bed and board from her if you can prove one of the 6 faults listed. This would mean that she would be the one to have to leave the home if you are awarded this.
I am not sure about the property distribution if one is found at fault since the description on the home page says: "A divorce from bed and board “suspends the effect of the marriage as to cohabitation, but does not dissolve the marriage bond.” The legislature has, however, directed that a spouse divorced from bed and board loses the rights enumerated in Section 31A-1(b) of the North Carolina General Statutes. Rights in property of the innocent spouse are likewise barred to the offending spouse, for so long as the parties remain separated, pursuant to Section 31A-1(d)(1)."
I have not read these GS so hopefully an attorney will post on this also and explain a little better.
