A lawsuit is not one invoice from your law firm. It is a stack of external, internal, and sometimes irrecoverable spend — phased across pleadings, discovery, experts, trial, appeal, and enforcement. Non-recourse litigation funders model the full stack before Tranche 1; claimants who only budget counsel fees routinely underestimate burn by 40–60% on commercial matters. This guide explains each layer, what funders ask for, and how to stress-test assumptions.

The cost stack (overview)
| Layer | Typical components | Visibility |
|---|---|---|
| External — pre-trial | Counsel, court fees, discovery, experts | Invoices, often lumpy |
| Internal | Executive time, PM, data room, IT | Often invisible in counsel-only budgets |
| Trial & appeal | Trial counsel, transcripts, further experts | Spike spend |
| Post-judgment | Enforcement, insolvency, recognition | Frequently omitted entirely |
Phase 1 — Pleadings and case management
Before document mountains arrive, spend accumulates on: issuing proceedings, defendant service, case management conferences, interlocutory applications, and security for costs disputes. In cross-border matters add translation, local counsel coordination, and jurisdiction fights. Funders model this as fixed plus variable — fixed for known court fees, variable for motion practice appetite.
Phase 2 — Discovery and document review
Often the largest line item. External: e-discovery hosting, processing, review platforms, vendor project management. Counsel review hours scale with corpus size and privilege complexity. See the 2026 review cost curve — AI assist saves first-pass cost until correction tax hits. Funders ask for €/page or €/doc bands with QC definition, not headline vendor quotes alone.
Phase 3 — Experts and technical evidence
- Financial experts — damages models, forensic accounting
- IT forensics — data breach, fraud tracing
- Industry experts — standards of care, regulatory context
- Single joint expert vs hostile parallel reports — cost multiplier
Phase 4 — Trial and appeal
Trial preparation concentrates partner hours, witness prep, demonstratives, and courtroom technology. Appeal tranches are incremental but not cheap — many funders cap appeal exposure in covenants. Settlement before trial avoids this phase; delaying settlement past a reasonable corridor often triggers useless spend flags.
Phase 5 — After judgment (the forgotten stack)
Enforcement, asset tracing, insolvency proceedings, and cross-border recognition can exceed trial cost. A judgment in England against a defendant with assets in multiple jurisdictions may require parallel enforcement counsel, translation, and local court fees. Funders who omit post-judgment stack misprice non-recourse risk.
Internal costs funders always ask about
See internal legal costs defined for detail. Summary: in-house legal and compliance time, war-room PM, data room hosting, forensic imaging, board review on group claims. Loading ordinary opex into litigation budget inflates burn; omitting incremental internal time deflates it — both distort Tranche 2 viability.
How funders use the stack in underwriting
- Baseline band — jurisdiction + claim type + Streitwert or damages band
- Adjustments — party count, cross-border, document volume, expert battles
- Waste haircut — seven useless spends history from monthly burn reports
- Tranche gates — Tranche 1 covers defined phases; Tranche 2 requires milestone proof
Anonymous planning vignette
A claimant budgeted €400k "all in" for German commercial litigation. Funder stack model: €280k first instance external, €120k document review slice, €80k internal PM and data room, €60k appeal reserve, €90k enforcement scenario — €630k planning band with ±20% sensitivity. Gap explained before funding, not discovered at month nine of burn.

Screening before funding
$50 dossier screening via Stripe or x402 does not replace stack modelling — it prioritises merits and red flags before committee time. See automation limits.
