ur question is not clear..........

U Can trasfer articles during the period of secondment without any restriction but you have secondment period of maximum one year.........

i mean - say for example, i joined firm-A in april2011 and took secondment in april 15th 2011 till august 15th 2011 for working in firm-B. Now after my secondment period is over, can i shift my principal itself to firm-B???
