M&A Insurance FAQS

What is M&A insurance?

M&A insurance protects buyers or sellers in mergers and acquisitions from financial losses arising from breaches of representations and warranties in the sale and purchase agreement. Many businesses work with M&A insurance brokers, like Miller, to structure policies that align with their deal strategy.

Why is M&A insurance important in a transaction?

It helps facilitate smoother negotiations, reduces the need for escrow or holdbacks, and provides peace of mind by transferring risk to an insurer. This can be especially valuable in competitive bidding scenarios or cross-border deals.

Who typically purchases M&A insurance—buyers or sellers?

Both parties can benefit. Buyers often purchase W&I insurance to enhance protection and reduce reliance on seller indemnities. Sellers may use it to achieve a cleaner exit with limited post-deal liability.

What does M&A insurance typically cover?

Coverage usually includes:

  • Breaches of representations and warranties    
  • Tax liabilities
  • Title and ownership issues
  • Compliance and regulatory risks
  • Exclusions may apply for known issues, fraud, or forward-looking statements.

How long does M&A insurance coverage last?

Policies generally last between three to seven years, depending on the type of warranty covered. Tax warranties often have longer coverage periods.

Can M&A insurance speed up the deal process?

Yes. By reducing the need for extensive seller indemnities and negotiations around escrow, M&A insurance can streamline deal execution and improve certainty for all parties.

Is M&A insurance available for small and mid-sized deals?

Absolutely. While traditionally used in larger transactions, insurers now offer tailored solutions for deals as small as £1 million

Can M&A insurance help resolve disputes post-closing?

Yes. M&A insurance can play a crucial role in mitigating post-closing disputes by clearly defining the scope of coverage and shifting liability to the insurer. If a breach is discovered after the deal closes, the insured party can file a claim directly with the insurer, reducing the need for litigation between buyer and seller and preserving the relationship for future collaboration.
