Law Firm Operations
Why NZ law firm mergers create operational blind spots
Mergers consolidate branding and letterheads long before they consolidate suppliers, contracts and operational knowledge. Here's what usually keeps running on legacy rails.
Most established NZ firms are the product of two, three or more earlier practices. The name on the door changed. A surprising amount of the plumbing didn't.
What usually does get merged
- Branding, website and letterhead
- Practice management (eventually — often the longest project of the lot)
- Email domain and identity
- The bank account and general accounting
What usually doesn't
Supplier contracts
Legacy agreements often stay in force because nobody wants to break something mid-term. Two dictation providers, two backup vendors, two phone contracts — all live, all billing.
Technology no one has retired
The old document store still holds closed matters. The old server still runs one thing nobody has identified. Neither has an owner.
Vendor relationships
A supplier knows one partner from the old firm and deals only with them. Nothing about that arrangement is written down.
Institutional knowledge
Why the firm chose that trust accounting product. What the notice period was. Which renewal was negotiated down and on what basis. That lives in the heads of people from one side of the merger.
Why it's a real risk, not just untidiness
- You pay twice for overlapping systems, often for years
- Renewals arrive from contracts nobody remembers signing
- Continuity planning is wrong, because the dependency map is wrong
- When the legacy-firm partner or practice manager retires, so does the explanation
A practical post-merger audit
- Pull the last three months of bank and card statements from every legacy entity.
- List every recurring payment, no matter how small.
- For each: which legacy firm signed it, is it still used, who owns it now?
- Mark each as consolidated, to consolidate, or genuinely dual-track for a reason.
- Record contract reference, notice period and renewal date for everything that stays.
- Give every surviving system and supplier one named internal owner in the merged firm.
You are not trying to rationalise everything in one pass. You are trying to make sure nothing is running that nobody owns.
