Results of electrical resistivity and ^{119}Sn Mössbauer effect measurements for two samples of CeAg_{2}Sn_{2} compound are presented. A sharp drop in resistance of an annealed sample at 3.5 K might have suggested a superconducting transition while for the as-melted specimen only a modest change in ρ vs. T slope is observed at this temperature. Resonance γ-absorption reveals differences and similarities on a microscopic scale between the two samples. The occurrence of certain regions of a long-range magnetic ordering within the CeAg_{2}Sn_{2} phase is unambiguously demonstrated by the presence of hyperfine splitting. Temperature variation of the hyperfine field follows a molecular field spin-½ function.
