I am still waiting to hear back from my lawyer but I thought in the mean time I could ask you. What are my chances if I didn't have a lawyer before. My sister donated her eggs to me through TCART and we signed papers there. Now its been over two years and she doesn't want me to use her eggs again. We just had a baby girl using the donor egg and my husbands sperm. We have frozen embryos. We thought one more and that would be it. We are getting older and don't have time to waste. Can she stop us legally?
