If I was divorced in 2013 after 13 years of marriage can I still receive alimony and child support?

You always have a right to request child support for minor children. With respect to spousal support, you would have to look at the language of the divorce Judgement to see if the Court still has jurisdiction to award spousal support. Unless you expressly waived spousal support in the Judgment,the Court most likely would have reserved jurisdiction over spousal support in a 13 year marriage.
