Is divorce document on stamp paper made by panchayat valid to remarry

Hi, I am a divorcee NRI, and looking forward to remarry a divorcee girl. Her divorce happened in Bhusawal Bhor Panchayat leva patil samaj, she has a stamp paper document from them. i did some research and found that this is not considered as a legal document in the court of law. she need to have a court decree for us to go ahead. i want it to be legitimate as many things depend on this down the lane - her passport, visa and other stuff. Please let me know if a document from Bhor Panchayat is considered a legal document - which i believe is not. What options dose she have for going ahead?
