The process generally involves:

1. Filing a Caveat: Lodging a caveat with the Queensland Supreme Court to prevent the granting of probate or letters of administration.
2. Gathering Evidence: Collecting documentation and witness statements to support the grounds for contesting the will.
3. Mediation: Attempting to resolve the dispute through mediation or negotiation to avoid a lengthy court process.
4. Court Proceedings: If mediation fails, presenting the case in court where a judge will determine the validity of the will and the rightful distribution of the estate.
