No. A voluntary relinquishment of parental rights is permanent and cannot be rescinded.
You can relinquish rights, a court decides your obligations.
The voluntary relinquishment of parental rights can be done Pro Se, although it is advisable to obtain advice from qualified legal counsel. Contacting the clerk or administrator of the state family or circuit court in the city or county of residence can provide specific information. FYI, in the state of Illinois voluntary relinquishment of parental rights does not necessarily relieve the petitioning parent of financial obligations, unless the act is being taken to allow the child/children to be eligible for adoption.
The adoption would need to be reversed.
Not without proof of some type of neglect or abuse.
Yes since he can't do it. see link
The state of residence of the child, however the court is not likely to approve it. see links below
Other than the specific parent? Only if that parent is mentally incapable of doing so themselves.
Yes!
Not without the other parent agreeing to the relinquishment of his or her parental rights as well. Any parent can file for the voluntary termination of parental rights. It is the judge's decision whether it will be granted, and if so, to what extent. A TPR is not a legal instrument to be used as a way for a parent to be relieved of their responsibilities to their minor child or children.
In Illinois, you must be at least 18 years old to change your name without parental consent.
The age of majority in Illinois is 18.
