Olswang has announced further expansion into Asia through alliances with domestic firms in Hong Kong and Singapore.

In Hong Kong the firm has entered into a non-exclusive alliance with independent firm Haldanes. The 15-partner Hong Kong outfit focuses its offering around its media, corporate and litigation practices.

The firm acts for clients across Asia from its Hong Kong base and has an association with PRC firm TransAsia Law through which it operates for clients in mainland China.

The association gives Oslwang a presence in Hong Kong and Haldeans a presence in Singapore, where Olswang has its only Asia base. Haldeans is led by senior partner and criminal defence lawyer Jonathan Midgley.

Andrew Stott, head of Olswang Asia's corporate practice, said: "The fit is perfect as neither firm has a presence in the other's home territory and we share a joint sector focus as well as a number of clients and contacts."

In Singapore Olswang has entered into an association with boutique domestic firm Holborn law.

The two-lawyer firm is headed by managing director and founder Lakshanthi Fernando who was formerly deputy managing partner at Singapore firm LegalStandard.

The association allows Olswang to offer its clients a Singapore law capability through Holborn. International firms are not permitted to practice Singapore law without a Qualifying Foreign Law Practice Licence (QFLP). Currently five international firms hold QFLPs including Allen & Overy and Clifford Chance.

Olswang Asia managing partner Rob Bratby told Legal Week that the firm was not planning to immediately apply for a more formalised alliance with Holborn in Singapore under either a joint venture for formal law alliance – which would allow the two firms to share office space and some profit. However, he said the firm would keep these options "under review" as the relationship between the two firms "progressed and deepened".

Olswang has worked closely with Holborn and Haldanes prior to entering associations and has multiple clients in common with each firm.

Last week Oslwang announced the hire of corporate partner Toby Grainger from Ashurst bringing the firm's partner headcount in Asia to five.

Oslwang's new alliances are the latest in a series of tie-ups by firms in the region. In November Herbert Smith Freehills formalised its relationship with alliance firm Prolegis, entering into a formal law alliance with the Singapore outfit.

Earlier this year Withers entered an FLA with Singapore's KhattarWong while Clifford Chance joined with Cavenagh Law under the same structure in 2012.
