Do I have a chance to get awarded something if my mother married a man who adopted me when I was 2 years old?

First of all, I'm sorry to hear of your loss. The man who adopted you at two years old is legally your father. As such, you are entitled to inherit from him. You don't say if your father left behind a will or not, but if he did, that would dictate what you're specifically entitled to from his estate. If he did not leave a will, you are still entitled to inherit from your father, although the intestate succession laws would determine what percentage of his estate you are entitled to. I strongly recommend you have a consultation with an attorney in the area where he lived to discuss your options further. Good luck.
