What is the status of marriage if solemnized by a judge outside the court’s jurisdiction?
The marriage is valid as held by the Supreme Court in Navarro vs. Domagtoy :
Judges who are appointed to specific jurisdictions, may officiate in weddings only within said areas and not beyond. Where a judge solemnizes a marriage outside his court's jurisdiction, there is a resultant irregularity in the formal requisite laid down in Article 3 [of the Family Code], which while it may not affect the validity of the marriage, may subject the officiating official to administrative liability.
What is the status of marriage if the solemnizing officer is not legally authorized to celebrate marriage?
The marriage is void unless such marriage was contracted with either or both parties believing in good faith that the solemnizing officer has the legal authority to do so.
