As an expert in law, the notary public can issue directives or prescriptions related to a specific legal issue with the aim of resolving conflicts or dispelling doubts within the interpretation of how to apply certain regulations.

The notary, Jesús Gómez Taboada, has issued numerous directives on private international law (by determining the law applicable to a certain succession; specifying the economic regime of a marriage), on civil law, on comparative law (accrediting the law in force in a given country) , or interpreting last wish declarations (in particular, wills).
