The top seeded Indo-Japanese pair recorded a hard-fought 6-4 7-5 win over their unseeded rivals in one hour and 23 minutes in the opening round of the USD 551,000 hard court tournament.
They next face Serbian Janko Tipsarevic and Alexander Waske of Germany.
Saving a breakpoint and converting one on the rivals' serve put the top-seeded pair ahead.
The second set was also a close affair as Paes and Tecau dropped their serve once but negated that by breaking the opponents twice.
