Coop Board didn''t sign Recognition Agreement. I can''t t do refinancing for my coop apartment and sign off my exhusband''s name from certificate. Help!

I''m in a stage of divorce. As per our agreement with my ex, coop apartment belongs to me where I reside with our two kids, 12 and 25, for more than 10 years. In order to put my papers in order, began to do refinancing but couldn''t finish since Board Coop didn''t sign the Recognition Agreement. My ex wants to be out of Certificate. It could be done only during refinancing. Moreover, our daughter''s name could be put instead of his. My daughter helps me to pay mortgage and maintenance, so coop management was provided with all mine and my daughter''s financial statements, accounts, everything they need in order to make a dicision to sell my ex''s shares to her.Since coop didn''t give us any respond, it looks impossible to finish refinancing. Can someone help me and let me know what''s my next step. Should I hire a real estate lawyer or no one have power to deal with Coop Board and speed up the process?
