Frequently Asked Questions

Leave it Blank
What is family law, and why do I need a family lawyer?

Family law encompasses legal matters involving family relationships, such as divorce, child custody, and property division. You need a family lawyer to navigate the complexities of these issues, protect your rights, and ensure fair outcomes for you and your family.

How can I initiate the divorce process, and what are the grounds for divorce?

To initiate the divorce process, you typically need to file a divorce petition with the court. Grounds for divorce vary by jurisdiction but often include irreconcilable differences or specific fault-based reasons. A family lawyer can guide you through this legal process.

What factors are considered in child custody arrangements?

Child custody decisions prioritise the best interests of the child. Factors considered include the child’s age, physical and emotional well-being, the ability of each parent to provide a stable environment, and the child’s preferences (if age-appropriate).

How is property divided during a divorce?

Property disputes can be a contentious issue. It’s often divided based on factors like each spouse’s financial contributions, the length of the marriage, and the value of assets and debts. Mediation or negotiation may be used to reach a fair settlement.

What is the role of mediation in family law cases?

Mediation is a process where a neutral third party helps couples in conflict reach mutually acceptable agreements. It can be used to resolve issues related to divorce, child custody, and property division, often saving time and costs compared to litigation.

How long does it take to finalise a divorce or family law case?

The time it takes to finalise a case varies widely depending on its complexity, court backlog, and the parties involved. A straightforward divorce can take a few months, while more complex cases may take longer. We can provide an estimate based on your situation.

What are the alternatives to going to court in family law matters?

Alternative dispute resolution methods such as mediation, collaborative law, and arbitration can help resolve family law disputes without going to court. These approaches often promote more amicable solutions and can be less stressful.

What steps should I take to prepare for a child custody evaluation?

Preparing for a child custody evaluation is crucial if it’s part of your family law case. A child custody evaluator assesses various factors to determine the custody arrangement that is in the child’s best interests. To prepare effectively, consider seeking guidance from your family lawyer and be ready to provide relevant information about your parenting abilities, relationship with your child, and living situation.

What are the costs associated with hiring a family lawyer?

Family lawyer fees vary depending on the complexity of the case and the attorney’s rates. At O’Sullivan Legal, our lawyers offer initial consultations at no charge, and you can discuss fees and payment options during this meeting.

Can I modify child support or custody orders in the future?

Child custody and support orders can be modified if there is a significant change in circumstances, such as a parent’s relocation or a change in financial situation. Consult with our family lawyers to determine if your situation qualifies for modification.

What legal rights and responsibilities do couples in de facto relationships have under family law?

A de facto relationship, where couples live together in a genuine domestic partnership without being married, often carries legal implications. Family law may recognise these relationships and grant rights and responsibilities similar to those of married couples. It’s essential to understand how family law applies to de facto relationships, including issues such as property division and financial support.

What are consent orders in family law, and when should they be considered?

Consent orders are legally binding agreements reached between parties in a family law case, typically without the need for court intervention. These orders can cover various aspects, such as child custody, visitation, property division, and financial support. Understanding when and how to pursue consent orders can help streamline the legal process and provide clarity on important family law matters. A family lawyer can guide you through the process of creating and filing consent orders when they are appropriate for your situation.
