With an approved motion to modify.
Yes, if you feel the need to not support your daughter and take away from her.
No, the father must support his previous child. You knew this when you had a new child with him.
Neither of the parents have to pay because they both have a child.
The more likely outcome is that the father would use this as the basis for a request to modify support.
Yes, until you have filed and had approved an order to modify the existing support order.
Working on getting caught up on child support does not take away your rights to your child. If you are having difficulty paying your support because of job or income loss, you can petition the court to modify your agreement based on the new information.
Perhaps there are details that could provide an answer. Perhaps the father is unemployed and caring for the children while the mother works. Depending on the details, the father needs to take the issue to court if he wants to modify custody or child support. The current child support order must be followed until there is a modification. The court doesn't know about the situation until it is informed by the parties. So when you ask why the answer is probably because the father hasn't tried to do anything about the situation.
No. A motion to modify must be filed and approved by the court. A sole custody father can still be obligated to pay child support.
Wait two years and modify. An incorrect amount is interpretive, as sole custody father are still ordered to pay child support.
You can find sample letters to modify child support on legal websites, family law websites, or by consulting with a family law attorney. These letters should include information such as the reasons for the modification, any relevant changes in circumstances, and a request for a modification of the child support order.
Revenue does not modify child support obligations. You need to file a motion/petition in the venue that issued the order for support.
