The choice of diluent is dependent upon the extent of neurolysis desired. The use of higher concentrations of phenol might predispose to a higher incidence of vascular injury. Shelf life exceeds one year when the solution is refrigerated and not exposed to light.
You asked whether a person can get a modification of a child support order that is nearly 20 years old to increase the time period for paying child support by requiring payment until the child reaches an age beyond the age specified in the original order.
We found laws in 10 states that permit courts to order a parent to pay some portion of a child's post-secondary educational expenses. And two others extend the age of majority to a child's 21st birthday for child support purposes, thus permitting support orders to cover any child up to that age. Outside of these states, courts have issued conflicting rulings on the authority of judges to order child support payments after the age of majority. For example, judges in New Hampshire, New Jersey, North Dakota, and South Carolina have found this authority in those states' general child support laws.
