I am only licensed to practice in Colorado so I cannot provide you with legal advice on divorce, but I can provide you with some general divorce help for men regarding your child support laws question.
Where I practice, the courts will not consider a second job as part of gross income when the job results in the employment of the obligor for more than 40 hours per week or more than what would be considered full time employment.
Unemployed and Broke:
However, if the second job results in employment of up to 40 hours per week, it can be considered income for purposes of calculating child support.
Again, I am unable to provide you with legal advice on divorce and this should not be construed as an attorney-client relationship. Consult with a mens divorce lawyer for divorce advice for men.
