  In the context of the TraMoS project we present nine new transit observations
of the exoplanet OGLE-TR-113b observed with the Gemini South, Magellan Baade,
Danish-1.54m and SOAR telescopes. We perform a homogeneous analysis of these
new transits together with ten literature transits to probe into the potential
detection of an orbital decay for this planet reported by \citet{adams2010}.
Our new observations extend the transit monitoring baseline for this system by
6 years, to a total of more than 13 years. With our timing analysis we obtained
a $\dot{P}=-1.0 \pm 6.0$ ms~yr$^{-1}$, which rejects previous hints of a larger
orbital decay for OGLE-TR-113b. With our updated value of $\dot{P}$ we can
discard tidal quality factors of $Q_{\star} < 10^{5}$ for its host star.
Additionally, we calculate a 1$\sigma$ dispersion of the Transit Timing
Variations (TTVs) of 42 seconds over the 13 years baseline, which discards
additional planets in the system more massive than $0.5-3.0~M_{\oplus}$ in 1:2,
5:3, 2:1 and 3:1 Mean Motion Resonances with OGLE-TR-113b. Finally, with the
joint analysis of the 19 light curves we update transit parameters, such as the
relative semi-major axis $a / R_s = 6.44^{+0.04}_{-0.05}$, the planet-to-star
radius ratio $R_p / R_s =0.14436^{+0.00096}_{-0.00088}$, and constrains its
orbital inclination to $i =89.27^{+0.51}_{-0.68}$~degrees.
