About the practice

A specialist actuary for one of family law's most contested numbers.

Most actuarial practices treat family law superannuation as a sideline. We treat it as the entire practice — and that focus is what produces tighter, more defensible valuations.

FamilyLawSuper.com.au is a specialist offering of TCW Actuarial. Reports are signed by Yiannis (John) Tellyros, Associate of the Actuaries Institute of Australia (AIAA) and Consulting Actuary, with peer review on defined-benefit and SMSF certificate work by Dr Gaurav Khemka.

The practice was established because separating couples and the family lawyers who advise them deserved more than a generic superannuation valuation form. They needed a specialist who could isolate what each party brought into the relationship, project it forward through real fund returns, and stand behind that calculation if it was tested in court.

Independence first

We take instructions from either party, jointly from both, or from family lawyers and mediators. We do not take ongoing referral fees or retainers from any law firm. Every report carries an explicit declaration of independence and complies with the FCFCOA Expert Witness Code of Conduct (FCFCOA (Family Law) Rules 2021, Chapter 7).

Self-managed superannuation funds

Member-account reconstruction in SMSF environments, treatment of in-specie contributions, segregated/unsegregated tax positions, and reconciliation against trustee-prepared financial statements and SMSF auditor reports.
