Yes, FM is recognized in the Civil and Commercial Codes and related laws.

The principle in civil/commercial matters is that the will of the parties is the "supreme law" between them and that they are obliged to comply in the terms agreed upon them (pacta sunt servanda); however, if the parties did not agree any covenants or clauses in regards to FM, the statutory provisions in such regard would apply to rule the relationship among those parties.

Only if the parties agreed on such remedies on the contract, being that statutory provisions on civil/commercial laws do not contemplate them.

The party invoking the FM would bear the burden of proof in regards to the existence of the event outside of the contracting parties' control that excuse or delay the invoking party's performance, or permit the cancellation of the contract.

It is common that contracts require that a party seeking to assert FM as a basis for suspending or terminating performance must provide notice to its counterparty with certain formalities (i.e., in written, in certain domicile, etc.), and failure to timely send such notice may result in waiver or have other adverse consequences.

Not expressly provided in Mexican law. However, there is a general obligation of repairing any and all damages that are a direct and immediate consequence of a breach of an obligation or an unlawful conduct.

If the party invoking the FM supports its claim in evidence establishing that the event was beyond its control, was not able to foresee and was not able to avoid, the outcome shall be the excused delay on performance as long as the FM event stands, the adjustment of contractual obligations (as pricing) or even the early termination of the contract.

No, unless such concepts or remedies are agreed upon in the FM clause. Please note that is common for contracts to include other concepts or remedies, besides FM events, that might trigger modifications on the terms and conditions or even early termination, as for example a material adverse change. But under Mexican law, a material adverse change is not necessarily considered an FM event, being that for an event to be considered an FM event it should meet the following elements: external, insurmountable, unpredictable and unavoidable. So from the latter, the contract might include other concepts and remedies different to an FM event.
