The Catholic Church Annulment Process, Explained Step by Step

By The Annulment Lawyers Editorial Team · 2026-06-05

A Catholic annulment - properly called a declaration of nullity - is a finding by a Church tribunal that a marriage thought to be valid was in fact not sacramentally binding. It is distinct from a civil annulment, which is a ruling by a civil court.

Who can request a declaration of nullity

Either former spouse may petition. You typically begin through your parish priest or deacon, who connects you with the diocesan tribunal.

The tribunal steps

  1. Filing the petition with the tribunal through your parish.
  2. Gathering testimony from the petitioner, the former spouse (the respondent), and witnesses.
  3. Review by the tribunal and a defender of the bond.
  4. The decision, which may be appealed.

How it differs from a civil annulment

A civil annulment addresses the legal status of the marriage; a declaration of nullity addresses its sacramental validity. Many people pursue a civil divorce or annulment first, then seek the Church process.
