How long does a family law case take?

The duration of the finalization of the divorce varies from case to case. Arizona divorce proceedings have a 60-day cooling-off period, which starts when serving a divorce petition to the other spouse. When a divorce petition is filed by one spouse and the parties don’t have disagreements on any issues, the court generally announces a decree after a cooling-off period.

However, if you have a conflict with your spouse on crucial issues like child custody and division of assets, the finalization time increases. The duration will depend on the complexity of those issues.

Why can’t I file for divorce on my own?

Whether you plan to file for a contested divorce or an uncontested divorce, the assistance of an experienced divorce attorney is advisable. If your marriage has conflicts, you may not be able to negotiate your fair share due to your history with your spouse.

However, in an uncontested divorce, you may have difficulty dividing marital assets fairly and handling all the legal paperwork. Since 1996, we have provided clients with thorough guidance and reliable advocacy in matters related to divorce and family law.

Most Common Questions

Common questions involve divorce, custody, support, and property issues. Every case is unique, so legal advice can help clarify your rights.

The duration of the finalization of the divorce varies from case to case. Arizona divorce proceedings have a 60-day cooling-off period, which starts when serving a divorce petition to the other spouse.

When a divorce petition is filed by one spouse and the parties don’t have disagreements on any issues, the court generally announces a decree after a cooling-off period. However, if you have a conflict with your spouse on crucial issues like child custody and division of assets, the finalization time increases. The duration will depend on the complexity of those issues.

You must have lived in Arizona for at least 90 days to file for divorce as per section 25-312(A)(1) of the Arizona Revised Statutes.

Arizona courts don't favor a parent based on gender when determining child custody. Arizona Revised Statute Section 403.02(B) states that the court shall not give preference to a proposed plan due to the gender of a parent.

The courts serve the best interests of the child. Therefore, they only consider factors that may benefit the child. Some of these factors include:

  • Level of the child's relationship with each parent
  • History of child abuse or domestic violence
  • Potential future relationship between the child and each parent

Arizona courts consider a child's wishes about their living arrangements if they are mature and of a suitable age. But, this is not the sole factor they consider when determining living arrangements. So, where your child will live depends on the facts of your case.

Arizona is a no-fault state; therefore, you don’t need specific grounds to file for divorce. You only need to state that your marriage is irretrievably broken, and there is no hope of reconciliation. You don’t need to prove the fault of your spouse to file for divorce.

However, if you have a covenant marriage, you must establish a specific ground for divorce. You must either both agree to divorce or prove in a court that the other spouse has committed one of the following acts:

  • Adultery
  • A serious crime resulting in imprisonment
  • They abandoned you for at least one year
  • Physical or sexual abuse
  • Domestic violence
  • Living separately for two years
  • Regularly use drugs or alcohol
