The $\beta$-decay of $^{125m,125}$Ag into levels in $^{125}$Cd was investigated at the Holifield Radioactive Ion Beam Facility (HRIBF). Uranium-238 targets were bombarded with 50-MeV protons
with an intensity of 15 $\mu$ A, and the induced fission products were mass separated and deposited on a moving tape in the center of the VANDLE array consisting of $\gamma$-detectors and plastic scintillators.

A partial decay scheme has been assigned for both $\beta$-decay of the (9/2$^+$) ground state of $^{125}$Ag (consisting of 72 $\gamma$'s from 47 levels) and its low-lying (1/2$^-$) isomer (consisting of 16 $\gamma$'s from 14 levels). The energy of the low-lying (11/2$^-$) isomeric state in $^{125}$Cd is assigned as 188.5 keV. In both the isomer and ground state, evidence for $\beta$-delayed neutron emission was observed, with the resulting branching ratios of 4.6(12)\% for the isomer, and 1.2(2)\% for the ground state.
