I'm not a priest, canon lawyer or tribunal official. This is a general overview based on the U.S. bishops' explanation. Every diocese has its own forms and timelines, so please talk with your parish priest or diocesan tribunal about your case.
If you've been putting off asking about an annulment because it feels like a big, confusing process, you're not alone. This post walks through the general steps so it feels less mysterious. First, if you're new to the topic, read Annulment vs. Divorce: What Divorced Catholics Often Ask.
The big picture
A tribunal (a Church court) looks at one question: whether something essential was missing at the time of the wedding. If so, it can declare that a valid marriage didn't come into being.[1]
The steps, in general
- Start with your parish. Your parish can provide the information and forms to get started, and your diocesan marriage and family life office can help.[1]
- Submit the petition. The person asking for the declaration (the petitioner) submits written testimony about the marriage and a list of people who know the couple and are willing to answer questions.[1]
- The tribunal contacts your witnesses and your former spouse. The tribunal sends both your witnesses and your former spouse a questionnaire with a request for their testimonies.The tribunal contacts your ex-spouse because they have a right to be involved. If they don't want to take part, the case can still go forward.[1]
- The tribunal chooses a process. Based on the information submitted, a tribunal official decides which process is followed (for example the ordinary judicial process, the process before the bishop, a documentary process, or a Roman court). Both you and your ex-spouse can read the testimony submitted, except what's protected by civil law, for example counseling records.[1] If for any reason you fear for your safety because of this part of the process, make sure you make it known to the tribunal so they can be aware and make concessions if necessary.
- You may have an advocate. Each diocese has their process, and some may appoint a Church advocate.
- A decision. If the tribunal decides in favor of nullity, both parties are generally free to marry in the Catholic Church, unless there's an appeal or the decision includes a prohibition until certain issues are resolved.[1]
Your diocese may describe the steps differently or use different names (e.g., "case assistant" vs. "advocate"). Ask your tribunal for its current guide.
How long does it take, and what does it cost?
Every case is different. Much of this answer depends on you, the Petitioner, and how long it takes you and your witnesses to submit your paperwork. Once the paperwork is submitted, the tribunal reviews the case and determines whether or not they will accept it. Once the case is accepted, the clock starts.
The USCCB says the length depends on the type of process, and your diocesan tribunal can give you a more exact estimate.[1]
On cost, the USCCB says Pope Francis asked dioceses, whenever possible, to provide tribunal services free of charge; depending on the diocese, a nominal fee may be requested, fees are typically payable over time, and they may be reduced or waived in cases of financial difficulty. Other expenses can arise if experts are consulted or you hire a private canon lawyer.[1]
Choosing witnesses and preparing for the questions
The tribunal asks for people who are familiar with your marriage and willing to answer questions.[1] A few practical thoughts (my suggestions, not Church rules): - Ask early, and ask kindly. Tell people what you're asking and that they can say no. - Think about who knew you both at different times: before the wedding, during the marriage, and around the separation. - Be honest and specific in your own testimony. Tribunals can only weigh what they're given. - Keep your own notes. Dates and details can fade. The USCCB points out that crucial witnesses may pass away or memories dim over time.[1] - Ask your tribunal for its witness questionnaire and any guidance on how to complete it.
What waiting feels like
The bishops note that some people find writing out their testimony helps them understand what went wrong, and some say it allowed them to tell their whole story for the first time to someone willing to listen.[1] If this process is bringing up a great deal of pain, please also consider talking with a counselor, a spiritual director or your priest.
What if the answer is "no"?
Not every case ends in a declaration of nullity. One diocesan tribunal explains that each case is judged on its own merits.[2] Ask your tribunal about its appeal procedure and what comes next.
