Generally, No, but l laws vary from State to State. Also- it is not uncommon for a divorce settlement to specify that one or the other parent must pay for college education... In which case, you are legally obligated...
Usually, a good lawyer will not allow a client to sign a contract obligating them for expenses beyond the legal age to which the State mandates support.
If it has stopped, than no. see links below
Unless specifically addressed in the child support order, it's dependent on state law. Joining Dads House in Yahoo Groups can help in learning your rights. See related link
Child support is based upon age (usually 18), not education.
It's possible - this is usually decided when the order is first entered.
If the divorce decree is from the State of Arizona, the answer is NO. He will not be required to continue to pay child support once your daughter turns 18 or until she graduates from high school, but not past the age of 19, UNLESS your divorce decree specifies that child support is to continue until she graduates from college. Arizona Termination of support at 18 or until child graduates from high school, but not past 19 No statute or case law holding parents to a duty to college support in the absence of an agreement; courts will enforce contracts to provide such support. Solomon v. Findley, 167 Ariz. 409, 808 P.2d 294 (1991).
No support
If you were order by the court to pay child support, that support will continue until the child either graduates college or stops attending. I do not believe the court can order you to pay for college. However, as a father you should be willing to help.
No. Outside of child support you cannot force him to help out with college tuition and fees. Although he must continue to pay child support until the child either graduates from college or stops attending.
In most countries 18 is the age when young people legally become adults. If this is the case in your country, then when a child turns 18, child support would terminate unless they are still at secondary school (then support continues to the end of the school year) However, if you daughter is attending college she probably requires continuing parental support from you. It is a parents responsibility to help their child through college or university to the best of their ability, but then the money can/should be paid direct to the child and not to the ex spouse.
Until age 21, which is the age of majority in the state. see links
Yes, provided that is when child support stops in your state. In many states it runs as late as age 23. see links below
Only if written into the order. See links below
Probably not, but it depends on the laws in your area and what the support agreement actually says. Contact a lawyer to find out.
