A question, answered

“What are the grounds for annulment of marriage under the Family Code?”

A marriage may be annulled on six grounds existing at the time it was celebrated: lack of parental consent for a party aged eighteen to below twenty-one, unsound mind, consent obtained by fraud, consent obtained by force or intimidation, physical incapacity to consummate that is incurable, and a serious, incurable sexually transmissible disease.1

A void marriage is different. A marriage is void from the beginning where a party was, at the time of celebration, psychologically incapacitated to comply with the essential marital obligations.2

Illustrative example, over a document you provide. In the app, each footnote opens the real provision inside your own file.

Why it matters for law

Sounding right is not the same as being right.

A confident answer built on a case that does not exist is worse than no answer. Courts have sanctioned lawyers for exactly that. Tatsulok is built so it cannot happen.

Generic AI

Confident, unverifiable

  • Invents plausible case names and G.R. numbers that do not exist.
  • Answers from a training cutoff, not the current body of law.
  • Leaves you to check everything yourself before you can rely on it.

Tatsulok

Confident, verifiable

  • Answers only from the documents you provide.
  • Every claim is footnoted to the provision or case it came from.
  • If it is not in the source, Tatsu does not say it.
