Ashwell Prince will fill the role of Lancashire overseas player ahead of VVS Laxman's arrival at Old Trafford.
A nuggety left-hander from the Eastern Cape, Prince scored two centuries against England in the summer of 2008 to reclaim the Basil d'Oliveira Trophy for South Africa.
He is also the first non-white player to captain South Africa.
Prince’s presence could be vital in a Lancashire batting order shorn of former captain Stuart Law, and last year’s overseas player, Mohammad Yousuf.
Prince helped South Africa saved last year’s Lord’s Test against England, scoring 101 in the first innings. He also made 149 in a stand of 212 with AB De Villiers at Headingley, as the Proteas took an ultimately decisive 1-0 lead in the Basil d’Oliveira Trophy.
Left out of the Proteas one-day squad, Prince played eight matches for Nottinghamshire in August and September.
He made 33 against Sussex, only to see Murray Goodwin engineer an escape act and rob the Outlaws of the NatWest Pro40 title. Prince then struck 57 in the closing championship match at home to Hampshire, but could not prevent the defeat which cost Notts the Division One title.
Prince chose to join Lancs for the start of the LV County Championship
