he needs to see laws in washington state.
laws on divorce, community property, child custody, child support, spousal support/alimony.
then go from there.
i will say most states require you be a resident for 6mo-1 yr before filing.
does he think just because he makes all the money he would automatically get kids?
because in most places that is not a factor.
i had never worked for 12 years. i got a job 2 months before filing for divorce and i made just above minimum wage(not a lot for myself and 2 kids). my ex husband made over $115,000/year. i got primary custody.
a parent being homeless, addict, mental issues...those might sway faster before money.
