How SOL Calculator works on a live matter
SOL Calculator is the AI.Law tool civil litigators use for time, billing, and deadline management. Calculating a straightforward SOL takes 30 seconds. But when you add tolling, discovery rules, government notice requirements, and cross-jurisdictional borrowing statutes, the research takes an hour — and the stakes for getting it wrong are catastrophic. AI.Law returns the calculated deadline instantly with every applicable rule applied and every statute cited.
On a live matter it runs in 4 steps: (1) Enter case details, (2) AI calculates with all rules applied, (3) Review results with statute citations, (4) Deadlines tracked automatically. Input the incident date, jurisdiction, claim type, and client details — age at time of incident, government entity involvement, date of discovery if applicable.
A two-year personal injury SOL sounds simple until the plaintiff was 16 at the time of the injury (minority tolling), the defendant is a government entity (ante-litem notice required 6 months before suit), the injury wasn't discovered until years later (discovery rule), or the case involves claims in a state that borrows the shorter SOL from another jurisdiction (borrowing statute). AI.Law applies every applicable rule for your jurisdiction and claim type — including the ones you might not have thought to check. Minority tolling calculated automatically — AI determines when the minor turns 18 and applies the jurisdiction-specific rule for when the SOL begins to run.
Enter incident date, jurisdiction, client age, and claim type — get the deadline with tolling applied instantly. Simple input: date, state, claim type, client details — AI applies every applicable rule.

How It Works
Get started in minutes. No training required.
1. Enter case details
Input the incident date, jurisdiction, claim type, and client details — age at time of incident, government entity involvement, date of discovery if applicable.
2. AI calculates with all rules applied
AI.Law applies the base SOL, tolling doctrines (minority, incapacity, absence, discovery rule), government notice requirements, and borrowing statutes to calculate the actual deadline.
3. Review results with statute citations
See each calculated deadline with the applicable statutes cited, tolling rules applied, notice requirements flagged, and any exceptions noted.
4. Deadlines tracked automatically
Every deadline syncs to your matter calendar with escalating 90/60/30/7-day warnings. SOL alerts appear on your dashboard daily briefing.

Real input → real deadline
You enter: Ohio · bodily injury · incident 3/15/2023 · minor plaintiff DOB 8/1/2010 · no government defendant
AI.Law returns: Last day to file: 8/1/2030 (R.C. 2305.10 — two years from age 18). Minority tolling applied. Calendar sync with 90/60/30/7-day warnings.
Also flags ante-litem notice, discovery-rule triggers, and borrowing statutes when your facts require them.
Ohio & multi-state SOL questions attorneys ask
Does Ohio apply the discovery rule to medical malpractice claims?
Ohio recognizes a discovery rule for medical malpractice — the limitations period can run from when the injury was discovered or should have been discovered with reasonable diligence, subject to the statute of repose. AI.Law applies Ohio-specific malpractice discovery and repose rules when you select medical malpractice and enter a date-of-discovery if it differs from the incident date.
When does minority tolling start running in Ohio personal injury cases?
For most Ohio tort claims, the statute of limitations is tolled during minority and begins when the plaintiff turns 18. AI.Law calculates from the date of majority for bodily injury, wrongful death, and other claim types where R.C. 2305.16 applies — and shows the cited statute in the result.
What if my client was injured by a city-owned vehicle?
Ohio political-subdivision claims often require written notice of claim within a short window before suit. AI.Law flags government-entity involvement separately from the filing deadline so you see both the notice deadline and the suit deadline on the matter calendar.

AI.Law applies every applicable rule for your jurisdiction and claim type — including the ones you might not have thought to check.

Faster
Instant results — including the tolling doctrines you would have had to research
Calculating a straightforward SOL takes 30 seconds.

Easier
Enter the basics — AI.Law flags the complexity you might not have considered
You know the incident date and the claim type. AI.Law tells you not only the filing deadline, but also whether a government notice is required first, whether tolling applies, whether the discovery rule changes the calculation, and whether a borrowing statute might shorten your window. Every result includes citations to the applicable statutes so you can verify independently.
- Simple input: date, state, claim type, client details — AI applies every applicable rule
- Flags tolling doctrines and exceptions you might not have known applied to this claim type in this jurisdiction
- Results include citations to the specific statutes governing the SOL, tolling, and notice requirements
