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.
Age of Majority. In a majority of states, the age of emancipation is 18, absent other qualifying factors such as schooling. If your child graduates from secondary school before turning 18, your obligation to pay support typically stops on his 18th birthday. In Alabama and Nebraska, however, a child doesn't emancipate until age 19, even if he's completed high school. In the District of Columbia, Indiana, Mississippi and New York, you must continue supporting your child until he's 21, an age at which most students have long since completed their secondary education.
