5 Things to Know About This Leading Melbourne Family Lawyer Handling Complex Cases in 2026

For people facing separation, divorce or a complicated property dispute, choosing a family lawyer can be one of the most consequential decisions in an already difficult period.

The issues can extend far beyond the end of a relationship. Families may need to resolve questions involving children, property, businesses, trusts, investments, financial agreements and international assets. In higher-value cases, legal disputes can also involve business valuations, taxation, restructuring and complex financial arrangements.

Mark Parker, a partner at Lander & Rogers in Melbourne, has built his practice around family and relationship law, with particular experience in complex financial and property disputes. He has been an Accredited Family Law Specialist since 1991 and is currently listed by Doyle’s Guide as the 2026 market leader for Melbourne family and divorce lawyers.

1. Parker has decades of specialist family law experience

Family law encompasses a wide range of disputes, from relatively straightforward separations to cases involving substantial assets and complicated financial structures.

Parker’s professional career has been heavily concentrated in the field. Rogers says he has been an Accredited Family Law Specialist since 1991. The firm’s current profile also identifies him as a partner in its Family & Relationship Law team.

The specialist accreditation is relevant because it is not simply another professional title. Rogers says accreditation requires lawyers to have practised predominantly in the relevant field for at least five years and to complete a rigorous assessment process involving written work, a complex mock file, client interviewing, an examination and professional references.

Parker’s professional recognition has also continued into 2026.

Rogers says Doyle’s Guide named Parker the Market Leader for Melbourne’s Leading Family & Divorce Lawyers in 2026. He was also ranked Preeminent nationally and in Victoria for high-value and complex property matters and listed as a leading prenuptial agreement lawyer in Australia.

The firm says Parker has also been recognised in Best Lawyers in Australia since 2012.

Professional rankings do not guarantee an outcome in an individual case. Family law matters depend on their facts, evidence and the applicable law. But for a prospective client, a long record of specialist practice can be one factor when assessing a lawyer’s experience.

2. His practice focuses heavily on complex property and financial disputes

For many separating couples, property settlement may involve more than deciding what happens to the family home and bank accounts.

Financial disputes can involve investment portfolios, companies, trusts, professional practices, farms and partnerships. Determining the value and ownership of those assets can become a central issue in negotiations or litigation.

Parker’s professional profile identifies complex property disputes as a major part of his practice. The International Academy of Family Lawyers says his work focuses exclusively on complex property disputes and includes cases involving commercial issues, valuations, taxation and restructuring.

Lander & Rogers similarly lists his experience with trusts, large manufacturing companies, trading entities, professional practices, farming properties and partnerships.

That background can be particularly relevant where one or both parties own a business.

A business can be one of the largest assets in a relationship, but establishing its value may not be straightforward. The company may have retained earnings, intellectual property, property, debts or other interests that need to be assessed.

There can also be disagreement about how a business should be treated following separation.

For example, one person may want to continue operating a company while the other seeks a financial settlement reflecting their interest in the business. That can raise questions about valuation, ownership, control and the practical structure of any settlement.

Rogers has also published guidance on business valuation in family law matters, noting that business valuation can become important where former partners built and operated a business together and only one will retain it after separation.

3. Trusts, valuations and taxation can make a family law case more complicated

Family wealth is not always held directly in an individual’s name.

Trust structures, companies and other arrangements can create additional questions when a relationship ends. The legal treatment of those structures depends on the particular circumstances and the evidence available.

Parker’s practice includes cases involving family trusts and other complex financial structures. His profile specifically identifies experience involving trusts, commercial entities, valuations and restructuring disputes.

Taxation can also become relevant to property settlements.

Rogers has published guidance discussing tax and stamp duty considerations in family law property settlements, noting that the structure of a settlement can have implications for the parties and that appropriate legal and tax advice may be required.

For clients, this highlights why a complex financial dispute cannot necessarily be approached as a simple calculation of assets and liabilities.

A settlement that appears straightforward on paper may have practical consequences involving taxes, transfer costs, business structures or future ownership.

That is particularly important for families with substantial wealth or business interests.

The lawyer’s role may include understanding the financial structure, identifying relevant legal issues and working with other professional advisers where specialist financial, tax or valuation input is required.

Parker’s professional profile reflects this type of multidisciplinary experience, identifying complicated commercial issues, valuations, taxation and restructuring disputes among his areas of expertise.

4. Parker also has experience in international family law

Family disputes increasingly can cross national borders.

A separated couple may have property in different countries. One parent may live overseas. Children may have connections to more than one jurisdiction. Financial agreements may have been signed outside Australia.

These circumstances can introduce additional legal questions, including jurisdiction, recognition of agreements and orders, overseas assets and international parenting disputes.

Parker’s practice includes international family law. Rogers says he has experience with international disputes involving Australian family law and matters connected with Singapore and Hong Kong.

The International Academy of Family Lawyers also lists Parker as a member and describes his practice as having an international dimension.

International cases can be especially sensitive to timing and legal procedure.

For example, someone considering moving overseas with children after separation should obtain appropriate advice before taking action. Rogers has published guidance warning that parents considering international relocation with children should obtain legal advice about the relevant requirements and proper channels for seeking consent or court orders.

The same principle applies to international property and financial disputes. The laws governing an asset or agreement in another country may differ from Australian law.

For a client with cross-border circumstances, experience in international family law can therefore be an important consideration when choosing representation.

5. His practice covers parenting, child support and financial agreements

Although Parker is particularly associated with complex financial and property matters, his practice extends across other areas of family law.

Lander & Rogers lists parenting arrangements, family violence cases, child support, spousal maintenance, financial agreements and alternative dispute resolution among his areas of expertise.

Parenting disputes can require a different approach from financial litigation.

Separated parents may need to resolve where children live, how time is shared, schooling, travel and other issues affecting day-to-day care. Some matters can be addressed through negotiation or mediation, while others may proceed to court.

Parker’s profile says his experience includes alternative dispute resolution, private mediation and litigation involving parenting arrangements.

Child support is another area of his work. The firm says he has experience with applications under child support legislation and the preparation of Binding Child Support Agreements designed around children’s educational and developmental needs.

Financial agreements can also play an important role before or during a relationship.

Parker advises on Binding Financial Agreements for couples contemplating or already in a marriage or de facto relationship. His profile says these agreements can address property settlements, succession planning and intergenerational family wealth.

For families with significant assets, these agreements can be an important part of long-term financial planning, although their suitability and enforceability depend on individual circumstances and legal requirements.

What should clients consider when choosing a Melbourne family lawyer?

Parker’s professional background illustrates why prospective clients may want to look beyond a lawyer’s general title when selecting representation.

His current professional profile identifies him as an Accredited Family Law Specialist, a member of the International Academy of Family Lawyers and a partner at Rogers. In 2026, Doyle’s Guide again listed him as Market Leader for Melbourne family and divorce lawyers and Preeminent for high-value and complex property matters in Victoria.

His experience spans property settlements, business and trust interests, valuations, taxation-related issues, international disputes, parenting arrangements, child support and financial agreements.

For a prospective client, that combination is most relevant where a family law matter involves more than a conventional separation.

At the same time, professional recognition should be considered alongside the specific needs of a case. No lawyer can guarantee a particular result, and family law disputes are determined according to their individual facts, evidence and applicable legal principles.

For people considering legal representation in Melbourne, understanding a lawyer’s specialization, experience and approach can be an important first step before deciding how to proceed.
