My mother and father were married he left when I was 3 I am now 24 we found him last year and he claims is now remarried but my mother never signed divorce papers is this legal?

If your mother never signed divorce papers, then legally, she is still married to your father, which means his remarriage could be considered invalid in many jurisdictions. However, the specific laws can vary by state or country, so it’s essential to consult with a legal professional who can provide advice based on your specific situation. Additionally, the fact that he has remarried may complicate matters regarding any legal claims or rights.
