Under the laws of all states in this country the amount of spousal support that one spouse may be required to pay the other after 30 years of marriage depnds upon the incomes of both parties, the standard of living of both, what further education or training the one spouse who wants spousal support needs for the possibility of getting a job and court guidelines in the county where you reside for such.I suggest that you see a family law attorney to ascertain potential monthly spousal support amounts. From what you have written, $1,000 to $1,250 monthly could be a possible spousal support amount assuming such is requested.
