The trust will bear their medical and education expenses, Yashwantrao Chavan Pratishthan's state organiser Nilesh Raut told a press conference here.
30-year-old Vijaymala Mahadev Patekar, a sugarcane cutting labourer, died on May 18 due to heavy blood loss after second trimester abortion conducted at a clinic run by a doctor couple in Parli tehsil.
The doctors and her husband Mahadev Patekar have been booked under charges of culpable homicide not amounting to murder.
Raut said the organisation has taken the responsibility of educating Vijaymala' four daughters Rohini (11), Tejaswini (9), Rutuja (8) and Rama (2).
District Guardian Minister and Minister for Public Works Jaydutt Kshirsagar has been given the local guardianship of the girls, he said.
