Commercial Penalties in Mexico: Late Fees and Agreements

Even though mercantile businesses operate in strong financial leagues (Business to Business), under the Civil Code regarding punishment for default, the laws protect even corporate institutions in courts under the mantle of general precedent. The real estate owner of a commercial or corporate zone has the right to seek lucidity and demanding lucrative interest to the penal sanction if the delayed owed quotas fall from very high rents in order for it to be forceful to finances and avoid a prolonged game—without crossing the boundary of illegally proscribed and usurious charges that the Power of the judges could lower and mutilate under amparos (constitutional protections).

1. Usury Also Exists at the Corporate Level

Historically errant or falsely there was a generally propagated legal commercial and civil myth in popular culture when thinking about commercial laws or private rents. They thought: "You can fine an S.A. de C.V. mercantile entity in interest with infinite percentages per month without a ceiling because a business does possess infinite cash flows and a Civil Code allows no-quarter agreements".

The Mexican Supreme Court in 2014 and subsequent theses invalidated any similar principle for any physical or legal person. It is unanimous, the entire national spectrum rejects and considers Unconstitutional a debt where "Penalties or Fines Rates result openly Exploitative and excessive or abusive affecting the productive operative society without a fair equitable limitation". A civil court will forcefully lower de facto very high mercantile penalties such as the exaggerated punishments of "1% Daily Accumulative (Equivalent to the astounding and fatalistic 365% return in your favor in a single year) on debt."

2. Prudent and Justifiable Rate Types for Businesses

To maintain total rigor and imperative upon the corporate that delays quotas and for the sake of mutual judicial respect of the owner's financial coffers, a prudent and approved or advised scheme is traditional moderate indexing:

• Real Civil Percentage Fixed Rate: Express fixedly a "monthly" natural profitability interest, fractioned (Agreeing to a very firm "5% to 8% monthly exclusive for delay debts").
• Institutional Indexed Rates: Other corporations define it to the TIIE (Interbank Equilibrium Interest Rate) plus "X" additional differential points of the country's banking system. This assumes rigor like a natural mortgage or bank credit, fully shielding it as a non-usurious measure and unappealably healthy and exigible at the financial foot in lawsuits or formal claims against the social reason of the defaulter or solidary guarantors.

3. Operative Administrative Limits ("Cancellation of Supplies")

As a preventative measure, which usually turns out thousands of times to be the most crushing swift B2B deterrent weapon against slow charge quotas, bulletproof contracts in commercial offices will dictate the following or similar when facing lack of payments with base tolerances in the stipulated delay days:

The Legitimate Right over annexed infrastructure: "The Administrator shall have the explicit and irrevocable or validated faculty to suspend the enjoyment of direct connections of passage for prorated quotas in Common Areas and base Installations upon not collecting total payment (including its corresponding extra quotas for delay/default) preventing if necessary or cutting passive legal interruption or shutting down switchboard lines (plaza telephony), base internet or general administered conditioned central air as a general measure until regulating the total invoiced under term."

These types of pre-approved acts (if they do not violate rights to privative occupation) avoid having to litigate over passive money when they can establish strong penalties by temporarily and operatively cutting the tranquility and profit of the premises by stopping them and efficiently demanding they regularize their payment to the plaza owner's leasing matrix.
