In 1997, a father in Dayton, Ohio became one of the first men in the state to be legally "defathered." A DNA test proved he wasn't the biological father, but the court had no way to stop a child support order — not even for DNA. His case helped create Ohio's paternity fraud protections.

Then, in 2019, it happened again. A son. Years fighting to establish paternity. Years of being kept away. The same broken system.

Same father. Different county, different system — Hamilton County's bifurcated court forced him to learn an entirely new process from scratch. Same impossible choice: hire a lawyer at $5,000 — or represent yourself in a system designed for attorneys.

He chose to fight. No lawyer. Just statutes, sleepless nights, and a father who refused to lose another child to a broken system.

This model is the result. Every question he couldn't answer at 2 AM, every filing deadline he almost missed, every legal term nobody bothered to explain — it's all in here. So no parent ever has to go through that alone again.

What This Model Does

ProSe-Ohio is fine-tuned on 13,400+ Q&A pairs covering all 12 steps of an Ohio family court case:

Step	Topic	Coverage
1	Parental rights & triggers	Constitutional rights, ORC §3109
2	Getting served / responding	Deadlines, forms, jurisdiction
3	Can't afford a lawyer	Fee waivers, legal aid, law libraries
4	Filing motions	Format, drafting, service of process
5	Building evidence	Best interest factors (9 current, 26 under SB174)
6	Discovery	Subpoenas, interrogatories, depositions
7	GAL involvement	Cooperation, challenges, Sup.R. 48
8	Courtroom preparation	Procedure, objections, cross-examination
9	Adverse rulings	Magistrate objections (14-day deadline!), appeals
10	Order enforcement	Contempt motions, documentation
11	Modifications	Change of circumstances, relocation
12	Post-case	Co-parenting, record keeping

How It Responds

Defines every legal term in parentheses when first used
Cites specific Ohio law — ORC sections, Civil Rules, local rules
Gives step-by-step instructions with deadlines and forms
Assumes zero legal knowledge — plain English throughout
Warns when you need a real lawyer — honest about limitations

The Council of Agents (Coming Soon)

ProSe AI isn't just one model — it's a council simulating every person you'll face in court:

Agent	Role
Legal Guide	Your main advisor through all 12 steps
Magistrate Simulator	Asks the hard questions the judge will ask
Opposing Counsel	Cross-examines you to find weaknesses
GAL Simulator	Evaluates your focus on the child
Custody Investigator	Simulates the home study interview
Psychologist	Assesses attachment and parenting capacity
Witness Coach	Prepares your testimony for pressure

You walk into court having already faced every scenario. Most pro se litigants walk in blind.

Why Now: SB174

Ohio is passing its biggest family law reform in 25 years. Senate Bill 174 eliminates "custodial parent" labels, expands best interest factors from 9 to 26, and maximizes parenting time. ProSe AI is built to help parents understand both current law AND what's coming.
