Child contact

My son is battling to get contact with his children after a relationship breakup. He loves his children very much and does not want to lose contact with them. They mean the world to him and it would be detrimental to him and his family to lose contact altogether.  He is a hard working man who earns minnimum wage.  He needs £3,000 plus to help pay for a solicitor and court fees over the next several months.  Without the help of the public he will not be able to afford to get a solicitor or go to court and could lose all contact with his children and we would lose all contact with our grandchildren. As a family we would be very gratefull for any help given no matter how small.
