The reaction $\gamma p\to K^{+}\mathrm{\Lambda }\left(1520\right)$ using photoproduction data from the CLAS $g12$ experiment at Jefferson Lab is studied. The decay of $\mathrm{\Lambda }\left(1520\right)$ into two exclusive channels, ${\mathrm{\Sigma }}^{+}{\pi }^{-}$ and ${\mathrm{\Sigma }}^{-}{\pi }^{+}$, is studied from the detected $K^{+}$, ${\pi }^{+}$, and ${\pi }^{-}$ particles. A good agreement is established for the $\mathrm{\Lambda }\left(1520\right)$ differential cross sections with the previous CLAS measurements. The differential cross sections as a function of center-of-mass angle are extended to higher photon energies. Newly added are the differential cross sections as a function of invariant four-momentum transfer $t$, which is the natural variable to use for a theoretical model based on a Regge-exchange reaction mechanism. No new $N^{*}$ resonances decaying into the $K^{+}\mathrm{\Lambda }\left(1520\right)$ final state are found.
