The deal is worth £3.25m, with completion expected at the end of May.
Legal Post provides a document exchange and postal service in Scotland, delivering legal documentation quickly and efficiently. First Post operates a Downstream Access mail service in Scotland.
Upon completion, DX will combine Legal Post and First Post with its existing DX Exchange operations in Scotland.
Petar Cvetkovic, chief executive officer of DX, commented: “We are pleased to announce that we have agreed terms to acquire Legal Post and First Post, both of which are well-established operations that will enhance our customer offering. These businesses are wholly complementary to DX’s operations in Scotland and they will be stronger together for both sets of customers, increasing the number of members in a single Scottish exchange network and providing Legal Post’s members with access to DX’s existing members in the UK and Ireland.
“The enlarged operation in Scotland will enable significant efficiencies that will enhance the economic life of a bespoke mail service that is highly valued by its professional services members for its reliable early delivery and late collection times, whilst also offering a cost effective solution.
“We look forward to delivering a smooth transfer of Legal Post and First Post’s operations to our facility in Livingston over the coming months.”
