From Formation to Closing: Why Billing Discipline Starts with Onshore Counsel

Custodia Advisory | Private Equity | July 2026

Every private equity fund begins with a jurisdictional decision. Delaware, more often than not, for the management company and the general partner entity; an offshore domicile for the fund vehicle itself. Two counsel relationships, two fee structures, two Outside Counsel Guidelines regimes — and, if nobody is watching the seam between them, two sources of leakage.

This is where most billing governance conversations start too late. By the time a PE or asset management firm engages a legal operations review, the fund is closed, the invoices are reconciled after the fact, and the habits that will govern the next five vehicles are already set. Custodia Advisory works further upstream than that.

The onshore counsel's role is broader than most GPs realise

Onshore counsel — typically Delaware or Cayman-facing US firms — does far more than draft the LPA and file formation documents. They are usually the first point of coordination across the entire closing process: negotiating side letters, managing the subscription process, liaising with offshore counsel on the fund vehicle structure, and often setting the tone for how the entire engagement is billed.

That last point matters more than it is given credit for. Onshore counsel frequently sets precedent — in narrative billing standards, in block-billing tolerance, in how disbursements are passed through — that offshore counsel and downstream fiduciary providers then follow by default rather than by agreement. If the onshore engagement letter and OCG are loose, that looseness propagates through every vendor touching the fund from formation to closing.

Where the process typically breaks down

A few patterns recur across the platforms Custodia has reviewed:

• Formation-stage fee creep. Structuring calls between onshore and offshore counsel are billed by both sides, often without a clear allocation of who owns which workstream, resulting in duplicated narrative for the same conversation.
• OCG misalignment at the seam. The management company's OCG governs the onshore engagement but is never formally extended to the offshore fund vehicle counsel, leaving a jurisdiction-shaped gap in billing standards precisely where two teams are coordinating most closely.
• Closing-stage compression. As closing approaches, timekeeper discipline loosens — deadline pressure produces block entries, weekend premiums, and staffing that no one has benchmarked against the deal's actual complexity.
• No single point of e-billing accountability. With onshore and offshore firms both submitting through different platforms or paper processes, nobody on the client side has full visibility until well after the fund has closed.

None of these are failures of any one firm's competence. They are structural gaps that appear whenever two legal teams in two jurisdictions are coordinated by the client rather than governed by a shared standard.

What we do differently

Custodia's work sits between the general counsel or fund controller and the panel of law firms — not replacing either counsel relationship, but auditing and structuring the billing governance around them.

For firms navigating onshore/offshore formation specifically, this means:

1. Reviewing the OCG for jurisdictional gaps before the engagement letters are signed, so onshore and offshore counsel are working to one standard, not two.
2. Mapping the closing timeline against expected fee activity, so the client has a benchmark for what formation-through-closing legal spend should look like before the invoices arrive.
3. Establishing a single e-billing intake point, typically through Serengeti or an equivalent platform, so onshore and offshore narrative billing is reconciled against one set of guidelines rather than assessed firm by firm.
4. Auditing the first closing's invoices as a calibration exercise — catching drift early, while it is still cheap to correct, rather than after it has become the house standard for every fund that follows.

The cost of waiting

Legal spend leakage on a single fund formation rarely looks dramatic. A few block-billed days here, a duplicated structuring call there, an OCG clause that was never actually enforced. But funds are not one-off events — the same onshore and offshore relationships, the same billing habits, and the same unenforced guidelines carry forward to Fund II, Fund III, and every co-investment vehicle that follows. What starts as a small formation-stage gap compounds into a pattern.

The firms that get the most value from an OCG and billing review are not the ones with the worst invoices. They are the ones structuring their next fund and want the onshore-offshore seam governed properly from day one.

If your fund formation process would benefit from a single, disinterested review of where onshore and offshore counsel billing meets — before the next closing, not after — Custodia Advisory offers a complimentary single-matter audit as a starting point.
