Magnetic susceptibility data obtained above the magnetic critical temperatures of the intercalated transition metal dichalcogenides ${\mathrm{Cr}}_x{\mathrm{NbSe}}_2$ and ${\mathrm{Fe}}_x{\mathrm{TiS}}_2$ are indicative of the presence of short-range magnetic correlations (clusters) in a wide temperature range in the nominally paramagnetic state. Bearing in mind that the Cr and Fe atoms located between Se-Nb-Se and S-Ti-S tri-layers, respectively, are diluted with vacancies, these compounds can be considered as appropriate systems for the appearance of the so-called Griffiths phase. To identify the Griffiths behavior among the intercalated materials, the consistency of the magnetization behavior of these compounds, with that expected for the Griffiths phase, was tested using the scaling law proposed by Chan et al. [Phys. Rev. Lett. 97, 137201 (2006)]. As a result, the compounds ${\mathrm{Cr}}_x{\mathrm{NbSe}}_2$ with $x=0.33$ and $x=0.45$ and ${\mathrm{Fe}}_{0.25}{\mathrm{TiS}}_2$ are found to exhibit the Griffiths phase above magnetic ordering temperatures while other compounds demonstrate non-Griffiths behavior.
