Hi good day, I am a US citizen and want to file for my mom, however my mom has legal custody to my niece and want to put her the filing, advise pleas

Thank you for your question. It would be helpful to have a little more about your situation, but based upon what you’ve shared here, your mom would need to file her own application, you cannot file on her behalf. However, anyone can file an adoption complaint in New Jersey.  I understand that you need answers and need to protect yourself. I strongly suggest that you schedule a consultation with a family law attorney who has experience in adoptions as soon as possible, so that you can understand the implications for you.
