Why it exists

It started as a rough tool I built for my own desk — somewhere to look up probate costs without flipping through the fee scales every time.

Rod, you know what would be great — something I could quickly refer to when I’m with a client, or putting together a cost agreement.

— Melinda, over lunch

Turned out we weren’t the only ones. So it grew into this: a quick, calm reference for the moment a client asks what it’ll cost to administer their loved one’s estate — sparing both of you the uncomfortable fumble through scales.

Then I needed to look up an intestacy distribution. Then a colleague asked about the tax on a super death benefit. So I built those in too. Three tools, one quiet app — every section reference clickable for a plain-English summary and a link to the legislation.

What’s in it

Probate costs

Type the estate value. Solicitor’s costs, filing fee and GST appear underneath — properly rounded, properly broken down. Schedule 3 of the Legal Profession Uniform Law Application Regulation 2025 and the Supreme Court filing fees, cited.

Intestacy distribution

Who gets what under Chapter 4 of the Succession Act 2006 (NSW). Spouse, issue, parents, siblings, grandparents, aunts and uncles — per-stirpes representation, the statutory legacy with interest, the s 107(2) State carveout. Every cite is a hover.

Super death-benefit tax

Lump-sum tax under ITAA 1997 Subdivision 302-B. SIS vs tax dependant surfaced as two pills, the direct payment route and the via-estate (s 302-10) route both modelled. Medicare levy applied or not, depending on who actually receives.

A quote you can hand a client

The probate tab produces a one-page PDF with your matter reference, the full breakdown and the sources cited. Drop into a cost agreement, email to the client, or keep on file.

Citation popovers throughout

Every section reference is a click away from a plain-English summary and a deep link to legislation.nsw.gov.au (or AustLII for ITAA). No cryptic s 113 floating in a result panel without explanation.
