Ben firstly communicated very effectively to understand the situation and gave me ongoing feedback and options. He untangled the mess, clearly advised alternatives and potential outcomes, kept me informed every step of the way and got an outcome very close to what I had originally sought.

Family Law Sydney FAQs
Do I need representation? I haven't done anything wrong.
If you have been served with a subpoena or legal documentation of that nature, the best course would be to solicit the legal services of a divorce law firm like ours. Even if you believe you have done nothing questionable, we can advise on the optimal path forward and represent you if processes continue.
How much will this all cost?
Our family law team endeavour to make our services accessible to anyone who requires it. We’ll always try to provide reasonable rates. In your initial consultation, we will be happy to discuss your particular situation.
How long will my case take?
What documents will I need to have to formally apply for a divorce?
Is there a way to determine how much child support I’ll be paying/receiving?
There are calculators available online. The Services Australia Calculator can give an approximate estimate – however, as it is not an exact science and is determined case-by-case, the resulting amount could differ.
Does hiring a family lawyer mean I have to go to court?
Not necessarily. Our services are not limited to representation in the courtroom. We represent clients in advisory and mediatory capacities. Hiring a family lawyer does not indicate that further action can/will be implemented. Often, family law cases can avoid courtrooms with competent mediation and discussion with legal representatives and parties present.
Can you help me with overturning a decision made in family law court?
What is the difference between divorce and separation?
Separation refers to one party in a relationship deciding to end said partnership and alerting the other party. Separations can still occur whilst both parties live together as long as the intent has been communicated. A divorce is the legal and formalised dissolving of marital status.
