That sounds like an offense called Criminal Mischief, but the penalties depend on the amount of damage. You'll probably have to wait and see what you're charged with. Plus your criminal history (or lack thereof) and other things can factor in. Ultimately you should hire a lawyer.
I'd suggest contacting local area attorneys who do both guardianships and adoptions. The cost difference may not be as significant as you may think, and the processes are similar. Additionally just because the bio-parents can't or aren't able to care for the child right now doesn't mean that this will always be the case. You will certainly get attached to the child, and the child to you. Disrupting that later if the bio-parents change their minds would be possible with a guardianship, but not...
You need to hire an attorney or request court appointed counsel. You should not speak with law enforcement without an attorney present, and should stop making any statements to anyone else besides your attorney. You may have a defense, but an attorney would be able to evaluate the specific facts of your case and make the judgment.
The previous poster stated that child support continues until the child turns 19 or graduates from high school. That is not entirely correct. In South Dakota, child support only continues until age 18, unless the child is still in high school, in which case child support would continue until the child graduates from high school or turns 19.
If the child is still in high school and is less than 19 years of age, then the child support obligation would remain. If the child is not in high...
Those text messages could be used as evidence to prove a valid and enforceable agreement between you and the potential buyer. However, evidentiary requirements, such as laying a foundation for the text messages (who sent them, who received them, how do we know that they haven't been altered, etc.) would still be required. In addition, simply because you believe an agreement exists from those text messages does not mean that a judge would necessarily see things the same way and would find that...
It depends on the specific facts, where your case is being heard, who your judge is, and who the County Attorney is. I'd suggest retaining an attorney immediately, or requesting court appointed counsel.
First, make sure you are not having contact with him if there is a no contact order in place. If he'd like to have the no contact order withdrawn, he should write to the court and request that that order be lifted. Beyond those two issues, you'll really need an attorney (either retained or court appointed), as your questions are very fact specific. No one on a forum such as this one could really give you good guidance about what could happen and what to expect.
With a second probation violation filing, you're probably looking at jail time. You should retain an attorney or request court appointed counsel so that the amount of time can potentially be minimized and any extenuating circumstances can be presented.
You need to either retain an attorney or request court appointed counsel. It is not clear from your description exactly what occurred, and therefore it would be difficult to tell you in this type of a forum whether you'd have a defense.
