Enforcing OCG’s
Austerus Consultancy | Private Equity | Legal Spend | June 2026
Outside counsel guidelines are only as valuable as their enforcement. Most firms have them. Far fewer actually use them. Here is why that distinction is costing you more than you think.
The Problem
There is a particular kind of document that lives in the shared drives of legal operations teams across the private equity and asset management world. It is thorough. It is carefully worded. It was probably reviewed by senior counsel before it went out. It sets out, in reasonable detail, how the firm expects its outside counsel to bill, staff, communicate, and conduct themselves.
And in a significant number of cases, it is almost entirely ignored.
Not by the firm that wrote it. By the law firms that received it.
Outside counsel guidelines — OCGs — have become a standard fixture of sophisticated legal operations. Their existence signals something: that the client is organised, that they have expectations, that they take legal spend seriously. But existence and enforcement are not the same thing. And in the gap between the two, firms are losing money, consistency, and leverage — quietly, incrementally, and often without realising it.
"A fee pass-through without a defined scope, a rate cap, or a reasonableness standard is not a billing entry. It is an open invitation."
Why Enforcement Breaks Down
The reasons OCGs go unenforced are rarely dramatic. There is no single moment of failure. It is a gradual erosion, driven by a combination of relationship dynamics, resourcing constraints, and institutional inertia.
Law firm relationships, particularly in the private equity context, are long and layered. The partner who leads your fund formation work has probably known your GC for years. Challenging a billing entry — or worse, enforcing a guideline violation — can feel like introducing friction into a relationship that the firm values. So the challenge does not happen. The invoice gets approved. The precedent gets set.
Resourcing is the other constant. Legal operations teams at PE firms are typically lean. Reviewing invoices line by line, cross-referencing against OCG requirements, escalating non-compliant entries — this is time-consuming work, and when capacity is constrained, it is usually the first thing that slips. The invoice gets approved not because it was reviewed and found acceptable, but because it was not reviewed at all.
Over time, both dynamics compound. Firms that have never had a billing entry challenged begin to treat the client's OCGs as advisory rather than binding. Rate escalations go through without pushback. Staffing provisions are quietly disregarded. AI and technology surcharges begin appearing as standard disbursements. Each individual instance seems manageable. The aggregate is not.
What Non-Enforcement Actually Costs
The financial cost of OCG non-enforcement is real, but it is also frequently underestimated — because it is diffuse rather than concentrated. It does not appear as a single line item. It accumulates across hundreds of invoices, across multiple matters, across multiple firms, over multiple years.
Non-compliant billing entries that go unchallenged. Rate increases applied without the required notice period. Timekeepers billed at rates not approved under the relevant matter agreement. Block billing that obscures the actual work performed. Technology and AI surcharges passed through under disbursement provisions that were never intended to cover them. Staffing ratios that bear no resemblance to what the OCG requires.
None of these items, in isolation, breaks the budget. Together, they represent a meaningful and recoverable cost — one that, in our experience, firms are consistently surprised by when they first conduct a structured billing audit.
Beyond the direct financial cost, there is the cost of lost leverage. A firm that does not enforce its own guidelines has, in practical terms, negotiated away the value of having them. When it eventually does seek to push back — on rates, on staffing, on billing practices — it is doing so without the credibility that consistent enforcement would have built. The conversation is harder. The outcome is less favourable.
The Fiduciary Dimension
For fund managers, this is not purely an operational question. It is a fiduciary one.
Legal spend drawn from fund assets is subject to the same standard of care as any other cost borne by the fund. Tolerating non-compliant billing — particularly where guidelines exist that would have prevented it — is difficult to defend in the context of LP expectations around cost discipline and transparency. As fee scrutiny from limited partners intensifies and regulatory frameworks around fund expenses continue to evolve, the bar for what constitutes adequate oversight of legal spend is rising.
An OCG that exists but is not enforced does not satisfy that standard. If anything, it makes the position more difficult: the firm has documented what it expects, and has demonstrably failed to hold its providers to it.
What Meaningful Enforcement Actually Looks Like
Effective OCG enforcement is not about adversarialism. It is not about challenging every invoice or treating every law firm relationship as a commercial negotiation to be won. The best-run legal operations maintain excellent firm relationships precisely because their expectations are clear, consistent, and applied without exception.
In practice, meaningful enforcement requires four things.
1. Guidelines that are current
An OCG drafted three years ago is unlikely to address the billing landscape as it exists today — AI pass-throughs, evolved staffing models, changed rate structures. Enforcement begins with having guidelines worth enforcing. If yours have not been reviewed in the last two years, the gap between what they say and what firms are actually billing is probably wider than you realise.
2. A systematic review process
Invoice review cannot be discretionary or capacity-dependent. It needs to be structured, consistent, and applied across all matters and all firms. This does not require a large team — it requires a clear process and, in many cases, the right external support. Ad hoc review catches individual anomalies. Systematic review identifies patterns.
3. A willingness to challenge
Non-compliant entries need to be raised — not aggressively, not punitively, but clearly and consistently. Firms that know their invoices are reviewed and that non-compliance will be flagged adjust their billing behaviour accordingly. Firms that know their invoices are approved on submission have no incentive to change. The challenge itself is not the point. The deterrent effect is.
4. Escalation pathways that are actually used
OCGs typically include provisions for escalating persistent non-compliance. Those provisions are rarely invoked. Building a culture in which escalation is a normal part of the enforcement process — rather than a last resort — is what separates firms with functioning guidelines from firms with decorative ones.
The Bottom Line
If your outside counsel guidelines have not been reviewed in the last two years, the chances are high that they do not reflect the current billing environment. If your invoice review process is inconsistent or under-resourced, the chances are equally high that you are carrying non-compliant spend you have not yet identified.
Neither of these is an unusual position. They are, in fact, the norm across a significant portion of the market. The firms that pull ahead are the ones that decide to close the gap — not by overhauling everything at once, but by bringing the same discipline to legal spend that they bring to every other area of operational management.
The guidelines exist. The question is whether they are working.
Is Your Outside Counsel Framework Actually Protecting You?
We work exclusively with private equity and asset management institutions on outside counsel guideline reform, legal billing audits, and fiduciary service provider oversight. If your OCGs are overdue for review — or if you have never subjected your billing practices to a structured audit — we would welcome the conversation.
