Best Family Lawyers Sydney

We are recognised as the top and best family lawyers in Sydney by BestInAu and ThreeBestRated. We do our best to provide you with professional legal services. The types of issues we are asked to provide our client’s family law legal advice about includes the following:

1) Post separation parenting – who a child will live with, what time they will spend with the other parent. Historically, the legal terms used were “child custody”; “visitation”; “residency and “contact”. The shared parenting reforms implemented in 2006 removed those terms. One of the intentions of the reforms was discourage a child being used as a “pawn”, fought over by parents as if they were some kind of “chattel”. We now speak in terms of “live with”; “time”; “equal shared parental responsibility”; “communications”; “week-about”; substantial and significant time” and “information sharing”.

2) Property settlement – who gets what. Just what is a just and equitable property settlement in your case having regard to who contributed what and a relative comparison of each parties future financial needs.

3) Divorce and marriage – this can been a fascinating area of practice in the modern age, for example, we have acted for clients who have been married and simultaneously in a defacto relationship, and where there was an arranged marriage in a foreign jurisdiction.

4) Child Support and adult child maintenance.

5) Spousal Maintenance.

6) De facto relationships.

7) Same-sex relationships.

8) Surrogacy and artificial conception procedures.

9) Financial Agreements, including pre-nups.

10) Relocation.

12) Domestic violence.

13) Sexual abuse.

14) Family Counselling and Mediation.

15) Going to Court.
