Clifford Chance is sending lawyers to Kosovo to help the region get back on its feet.
Jeremy Carver, head of the firm's international law group, has got the go-ahead from the United Nations Mission in Kosovo for an internet project to support the rebuilding process.
Carver says: "One of the first projects was to develop a database, helping to reassemble refugee details. That is now done and has worked."
Carver returned from Kosovo on Monday for a second project to encourage foreign investment in the region.
Carver is looking at drafting laws to regulate the 150 to 200 non-governmental organisations currently operating in Kosovo. And he is putting forward plans to the authorities running Kosovo on how to spend more than $2bn in aid.
Carver was retained by the General Counsel of International Rescue, New York lawyer George Huritz.
A Clifford Chance spokeswoman says the firm's post-conflict capability will be boosted by US firm Rogers & Wells' trade and international law group. The two firms are merging on 1 January 2000.
Rae Lindsay, international law partner at Clifford Chance, says Kosovo is very different from other recent post-conflict situations.
She says: "Kosovo is in a transitional phase and a new regime has yet to be established. The infrastructure is gone. Documents and records destroyed.
"For lawyers developing contractual relationships, it's an unprecedented situation."
