If by spouse you mean their legally married spouse the answer is no. If you mean simply a girlfriend it's yes.
When I married my girlfriend she said I am her spouse.
Yes
No. In general, you are responsible for your debts, those that you have agreed (in writing) to pay for another, and those of certain relatives (spouse, minor child)
Equal rights and access see link
no
no... not her/his child ....that is called innocent spouse and the wages of a spouse that is not responsible for someone else's child when it is not biologically theirs.
No, unless the spouse is also a biological parent of the child.
Your question is incomplete. That being said, we'll try to anticipate where you were going with it, and give an answer based on that anticipation. Assuming you're referring to the girlfriend of a veteran, they're not entitled to anything. No educational benefits, no SGLI benefits, nothing. A spouse or child would be; a boyfriend or girlfriend is not. If the girlfriend is the veteran, she is entitled to benefits - her boyfriend (or girlfriend, if applicable) would not be.
Your spouse has no authority to over-ride a court ordered child support.
no, but he has a girlfriend i think her name is Ashley.
No the new spouse is not responsible.
