FAQs

What can I expect from my family lawyer?

We support our clients through every step of a separation and dispute resolution. We have a trusted network of psychologists, counsellors, tax professionals, financial advisers and valuers so our clients always have the best team to support them through the process.

What options are available to resolve my matter without going to Court?

Most of our clients will have their matters resolved outside of court. The most common way of reaching a negotiated outcome with your former partner is by way of mediation. There are a number of advantages of mediation, which avoids the costs and stress of court proceedings and allows the parties to have some control over the outcome. A third-party mediator facilitates discussions between the parties and their legal representatives over the course of the day and if an agreement is reached, it can be formalised by consent orders which becoming binding following approval from the court.

How will you work with other advisers such as accountants and financial planners throughout this process?

A lot of the information held by your accountant will be relevant to your family law matter, so with your written approval, we can connect with your financial team to obtain information relevant to your personal or corporate finances. We also have a close network of financial services professionals to whom we regularly refer our clients, particularly if they require advice following a financial settlement. Our extensive network enables us to connect our clients to a financial planner who is appropriately suited to their circumstances.
