An efficient and economical process to recover ligands from metallocene complexes, where the free ligand recovered may be recycled to produce additional metallocene and metallocene complexes. The process comprises contacting a metallocene complex comprising a ligand with a protic composition under reaction conditions to decompose the metallocene complex and form a reaction product comprising free ligand and inorganic decomposition products; and recovering the free ligand from the reaction product
