My mother father were married in Mexico i was born after father then remarried. His worth 500.00000. Do I have a claim when he dies

It depends on whether he had a Will and whether you can prove that he was your biological father.  If there was no Will and he was your biological father, you may inherit under Michigan rules of intestacy.  Please contact a probate attorney who practices in the county in which he died.  (Note that if he resided and died in Mexico, the outcome may be different.)
