Aparti
Aparti computes California guideline child support and temporary spousal support, New York guideline child support and maintenance, and Texas guideline child support, with the taxes under them, and Florida guideline child support from each parent's net income as entered, for family law professionals. A plan shows Aparti's figures on aparticalculator.com and, for California cases, in Claude or ChatGPT, and turns on the reports, which are printed on aparticalculator.com. Each state Aparti computes is included in every plan, with no charge per state.

Where the Service offers it, you can buy a product for one matter, with or without a plan, such as a court package or a two-way bonus table for a California case: priced once per case, on one line with your matter number, and revisions never bill again. The price is shown before you pay. A bought matter shows Aparti's figures and reports for that matter on aparticalculator.com, and, for a California case, its figures in Claude or ChatGPT. For now, some per-case products are available without a separate purchase, as early access, which is not part of any plan and may end at any time.
Every plan includes Aparti in Claude or ChatGPT for California cases: the same figures, from the same engine. A free account can connect, but sees none of Aparti's figures. How to connect, which chat plans can connect, and what to know about your client's data: Use Aparti in Claude or ChatGPT.
We have applied to the Judicial Council of California for certification under Family Code section 3830 and rule 5.275. Every figure Aparti produces is an estimate; a court decides the amount of support in every case. Not legal advice.
