Is slow legal work stalling your deal?

It can take one to two months from receiving disclosure materials to getting a legal DD report, and during that time neither price negotiations nor the closing schedule can move. Under hourly billing, the total legal cost is not fixed at the start, which delays the decision to engage counsel in the first place.
- Legal DD takes so long that the whole deal stalls
- Legal costs are hard to predict, so you hesitate to engage counsel
- You are unsure how to reflect DD findings in the SPA

Acquisition finance
Acquisitions financed with LBO loans, supported together with the SPA
In an M&A deal financed with an LBO loan, the SPA's conditions precedent and the loan agreement's conditions to drawdown must both be satisfied on the same closing day.
We run the two tracks in parallel, with the same team through to the funds settlement on the day.
Share purchase agreement (SPA)Buyer ⇄ Seller
- Conditions precedent
- Reps and warranties
- Termination events
LBO loan agreementBuyer (SPC) ⇄ Lenders
- Conditions to drawdown
- Financial covenants
- Events of default
- Loan drawdown
- Payment of the purchase price
- Repayment of existing debt
- Delivery of security documents
We manage the order of remittances and the required documents with a funds flow memo and a closing-day run sheet.
- Term sheet and loan agreement
- We check the conditions to drawdown, financial covenants, restrictions on dividends, investments and additional borrowing, and mandatory prepayment clauses against the business plan, and set the approach for negotiating with lenders.
- Negotiation memo / list of requested changes
- Security, guarantees and target company procedures
- We examine share pledges and other security, the timing and corporate approvals for security and guarantees provided by the target, and restrictions on granting security in existing contracts.
- Security timetable / draft minutes
- Repaying existing debt and releasing guarantees and security
- We sort out whether prepayment is allowed, how the payoff amount is fixed and the conditions for releasing personal guarantees and security, and settle which documents to obtain from lenders.
- List of existing debt, guarantees and security / release document checklist
- Post-closing management
- We manage the merger of the SPC and the target after the acquisition, additional security, and covenant reporting deadlines.
- Procedure schedule / covenant tracker
We act for buyers, borrowers and target companies. Fees for deals with LBO loans are quoted individually after we review the structure, the volume of documents and the time to closing. For more, see LBO and Acquisition Finance.

FAQ
Frequently asked questions
At what stage can we engage you for M&A legal work?
From the initial review stage. We can start with structuring the transaction, reviewing the NDA and letter of intent (LOI), and designing the disclosure request list and the legal DD scope.
Can we engage you for legal due diligence only?
Yes. Depending on the target and the deal size, we can also conduct red-flag DD focused on priority areas such as contracts, labor and licenses.
What do M&A lawyers typically charge?
Legal DD alone ranges from several hundred thousand yen to several million yen depending on the target's size and the scope, and under hourly billing the total is not fixed at the start. At LegalAgent, summary-format DD for target companies incorporated within the last three years starts at JPY 500,000 (tax excluded), with a fixed fee quoted before engagement.
How long does DD take?
We can complete DD in as little as two weeks from the kickoff meeting, provided that disclosure materials from the target company are in place. The timeline varies with the volume of materials, the scope and the Q&A process.
Can you support acquisitions financed with an LBO loan?
Yes. Together with legal DD and the share purchase agreement, we support the LBO loan agreement, security and guarantees, repayment of the target's existing debt and release of its guarantees and security, and the funds settlement on the closing day, as one engagement.
Can you act for sellers?
Yes. We support sellers with preparing disclosure materials, setting up the data room, Q&A, negotiating the SPA's reps, warranties and indemnities, and preparing for closing.
