In the local rules of some counties there is a requirement to go to mediation prior to a final hearing. If your husband doesn't agree to attend mediation then you may be able to file a Motion to Compel Mediation. Then, hopefully, you can work out the details of the decree. If you don't reach an agreement, then you'll need to have a hearing.
A mediated settlement agreement is very difficult to revoke. However, there are special circumstances that allow a party to revoke the agreement. You'll need to discuss the issue in more detail with a competent attorney who can advise you. It may be easier to discuss an agreement to change the one day a week provision in the final order instead of going through the process of revoking the MSA.
An answer is required to be filed within 20 days or else the other party can get a default judgment. If you have missed your 20 days go ahead and file it NOW. Do not wait another day. File right now. If you're lucky, the other side hasn't gone to court to request a default.
You can then talk to a lawyer and figure out if you want to file a counter-petition requesting your own relief. I wouldn't do anything to "get back at her," that's the wrong mindset for a legal argument over your...
Child support is money that goes to help financially support the child. Supervised visitation fees are fees spent to support the facility that is having to provide a place to watch the child and the parent, plus a supervisor, etc. So you can't look at the money spent on supervision as child support. It literally does nothing to support the child.
If the supervised visitation is too expensive, then perhaps try to find a place that has a sliding scale, or see if the court may agree to a...
You really need an attorney to review this. If it's done right you won't pay taxes on it. The first question I have is how are you going to receive the $40K? Is he supposed to pay you at some later date? You don't want an unsecured money judgment. At least secure the money with a lien. If the money is for your interest in the home then you could even do an owelty lien on the house. That way if he doesn't pay you then you have a way to recover it.
You made an agreement with the creditor when you signed the loan on the car. And that loan is in your name. A divorce will not change the name on the loan. So if your husband doesn't pay the loan then it will hurt your credit. If he can't refinance the car into his name then you may want to keep the car, or sell it and divide the proceeds. Don't give debt to someone to pay if they will have no negative consequences when they don't pay.
Yes, you need to keep insurance on the car.
Some legal things are more complicated than others. I believe an adoption to be something you would want to hire competent legal counsel. If you made a mistake it could have very severe consequences.
There may be legal help for low income families in your area. I would research various resources that are available and hire an attorney.
You may be able to request a reduction in your child support if you are no longer able to pay the amount you previously could. There are situations in which the court finds that a person is intentionally unemployed or intentionally underemployed and does not reduce the child support.
You may be able to get a slight reduction due to another child.
Generally, the custodial parents income is not considered when making a determination about child support. And step-parent income is also...
You would file a petition to change a child's name. Within the petition you would allege why the name should be changed. I would suggest hiring an attorney to help you with the process. I wouldn't wait too long to do it as the court may consider how old the child is in determining whether or not a name change would be in her best interest.
