Was married for a little over 10 years. I make significantly more than my spouse. A little more than 3 times of her gross income. Is there a way to tell how many years of alimony I am liable for? She has a steady job as a teacher and I supported her to get her certifications with next to zero contribution from her during the course of the marriage.

Also can the Child Support Guideline be overridden because I am a high income earner? Could it be subjective rather than based on defined calculation rules?

State: New Jersey

Appreciate any input!!
