You cannot waive any mandatory forms if you want a valid legal separation (or divorce). Forms are steps, and you can’t skip steps. Think of it like wanting to fill a prescription of antibiotics for your child. There’s a process you must follow. Even if you know your child needs antibiotics, you still have to get a prescription. You can’t just call up the pharmacist and order it on your own. You can’t tell the pharmacist you know what you want and to give it to you because you want to save time and money from going to a doctor’s appointment. You can’t tell the pharmacist you and your spouse agree that your child needs antibiotics. You can’t talk to friends who have filled their own prescriptions validly and try to use their prescription to fill yours. That you and your spouse agree that your child needs medicine does not change the process of getting it.
You can spend lots and lots of time and energy trying to circumvent the process and end up not getting the medicine you need, or you can simply follow the steps everyone else takes in order to get the result you want. At the end of the day, to get the antibiotics, all you need to do is visit the doctor, get the prescription, and then fill the prescription. Period. Whether you do it the “easy way” by following the process, or the “hard way” by trying to figure out an exception and ultimately having to do what everyone else does is your choice.
