Dear Nirma, Yaasmin is right - "do a search first in this forum." The question you have posted may look simple, but the applicability in this case may be complex.
For example:
The answer to your query is simple.
Q.1: "If any female employee has joined just two months back, is she applicable for maternity leave?"
The answer is NO.
Q.2: "If not, what is the minimum tenure from her date of joining?"
The answer is: she must have actually worked for a period of not less than eighty days in the last twelve months.
That's the answer to your queries.
But the matter does not end here; as you have not mentioned "the date of her expected delivery," a lot hinges on this date, including the notice to the employer for maternity benefits.
For example: if a female employee joined on 1st Nov. 2010 and as of today, i.e., 1st of Jan 2011, she has only completed 2 months; however, she will still be eligible for Maternity Benefits from 21 January onwards if her expected date of delivery is on 4th March 2011 or thereafter.
I hope you are able to comprehend what is being implied/stated. Do revert back in case you have any doubts. You asked, "Pls reply fast...."; I hope the reply is fast enough.
Wish you (and all members) a very Happy New Year!!!
Warm regards.
