Resolved: Child's consent should be required for parent's divorce

My opponent provided 4 factors to consider. The factor of age is very obvious. Of course, a baby would not have any right to veto divorce between parents. Thus, I would like to define the word "child" as child who is at least 11 years old. Second factor, maturity, is a considerable point, but is also a problematic point. Some children are so mentally mature that they could be even called as young Confucius or young Socrates. On the contrary, some are not only mentally immature, but often makes problem, and is not temperate. Well, everyone knows that, but how would you define the standard of maturity. The problem of building the standard of maturity seems to be not working. It is very hard to objectively cut a straight line between the mature and the immature. How would you legally define whether someone is mature or not, and empower with them the right to pass or veto the divorce? If it was possible, then it would make all those divorce decision would be ideal. Unfortunately, we could not clearly cut the line of maturity with an mental test, school grade, or even IQ test. Same logic should be adapted with the factor of relationship and temperament. We can not define the standard, by any means. Since, unlike age, other factors that my opponent gave me are all unable to clearly decide the standard, I would not define the children, as those who are mature, temperate, and having good relationship with parent. Well, if we are talking about all children generally, we will have to face a huge risk. Risk is often expressed as product of probability and damage. Well, this time, both are high. Obvious one first. The damage of wrong decision of allowance for divorce will make serious psychological harm to the child, parent, and the family. Due to one wrong choice of an individual, 3 or more lives have to suffer metal hardship. In the case, where the child vetoed the divorce, what if the parent retries to divorce? Those who made an unwise choice, might make another unwise choice again, even if they suffered from metal hardness. They can be so stubborn, which is not rare among those un-temperate children. Even if the family relationship is very bad, they might still want to retain the family, which is harmful for all the family member. The opposite case is even more deteriorating. A failed-to-divorce parent could divorce, in the second attempt, but those who chose to make the parent leave would probably never see their parents together. They will regret, if they made the wrong choice and they just acknowledged what he or she just have done. Now what about the probability. I strongly believe that this kind of scenarios will occur a lot. Even if the child is not so absurd, and shows good state in the school and with pupils, and have a three digit IQ, the children would lose the control in that kind of situation. The children might just cry for days that he or she faced this situation, where parents want to separate, and the choice is one's hand. With sudden impulse, the children irrationally could choose the wrong choice. A family with bad relation might not be separated due to child not wanting to be unable to see one side. On the other hand, even if it might be not a good choice to divorce, but he or her just shouts out to the parent to divorce, only with abhorrence or sudden anger, and the wrong idea from parent is concluded by wrong decision of child. It doesn't seem to be a rare situation. High probability with high damage makes high risk. In conclusion, I would firmly argue that there is no need to take this risk or only advantage when the child is rational and mature at the same time in that kind of chaotic situation.
