London Stock Exchange Group (LSE) and Deutsche Boerse are expected to pay out at least £102m between them in legal fees for advice on their proposed merger.

Documents filed on the LSE earlier today show the exchange expects to spend a minimum of £55m on legal advice relating to this deal, with this figure potentially rising as high as £62.4m.

Its German counterpart meanwhile anticipates spending between £47.01m and £49.2m.

Freshfields is advising its longstanding client the LSE with a team consisting of corporate partner Andrew Hutchings and and London M&A co-head Piers Prichard Jones. Former partner Mark Rawlinson initially advised on the matter.

Linklaters is advising Deutsche Boerse, with London corporate partners Roger Barron and Simon Branigan and Germany corporate partners Ralph Wollburg and Staffan Illert advising.

Looking at total advisory fees for the merger, including those paid out to financial advisers, accountants and public relations companies as well as law firms, the LSE anticipates spending up to £175.2m, with Deutsche Boerse expecting to spend up to £122.9m.

In October 2015, Freshfields also won a mandate to advise LSE on a deal to sell asset management company Russell Investments for $1.15bn (£752m) to US private equity group TA Associates.

On that deal the team included Peter Lyons, co-head of Freshfields’ M&A group, New York corporate partner Doug Bacon and Hutchings.

Linklaters has acted for Deutsche Boerse in the past, including on its talks with NYSE Euronext in 2011. That deal came to nothing after the European Commission blocked the proposed $9bn (£6.4bn) tie-up in 2012.
