Yes, as part of a legal separation.
yes
In general, no. (I suppose the answer might be different if she married Donald Trump.)
NO!
Yes. Child support is for the "custodial parent". If you are not living at home with your custodial parent, then they are no longer eligible to receive child support. However, the non-custodial parent can request a modification if the child is no longer living with the custodial parent and that includes a change of custody. A 17 yr old is not emancipated in Texas, unless proper procedures through the courts have taken place. If that is the case, then the custodial parent and child are no longer eligible for child support.
Currently, nothing specific. After all, the parent paying child support is still the child's parent and obligated to support her. Only five states specifically take it into consideration.
Being married does not automatically stop child support. Child support is a legal obligation that exists to ensure the well-being of the child. It is determined based on factors such as custody arrangements, the income of both parents, and the needs of the child. Marriage alone does not release a parent from their financial responsibility towards their child.
If the arrangement is with the consent of the custodial parent and will be permanent then the custody and child support orders must be modified to reflect the change in legal custody. The parent in Texas needs to have their custody formalized by a court order so they can enroll the child in school, consent to medical treatment, etc. If the child support order is not modified the non-custodial parent may be subject to the accumulation of child support arrears.
yes. see link
Generally, the parent with the greater amount of physical custody is entitled to child support.
Technically arrears cannot be waived. However, a custodial parent can fill out a form stating that no child support is due.
GET A FAMILY ATTORNEY
That would be up to the judge.
